| 20090244451 | LIQUID CRYSTAL DISPLAY DEVICE AND ELECTRONIC APPARATUS - A liquid crystal display device includes: a liquid crystal layer interposed between first and second substrates; a first electrode provided on a side of the first substrate facing the liquid crystal layer; and a second electrode having a plurality of linear portions, an electric field being generated between the first and second electrodes. A reflective display portion and a transmissive display portion provided with the first and second electrodes are included in one pixel. The thickness of the liquid crystal layer in the reflective display portion is set smaller than that of the liquid crystal layer in the transmissive display portion. First and second polarizers having transmission axes approximately perpendicular to each other are provided on outer sides of the first and second substrates, respectively. The transmission axis of one of the first and second polarizers is set approximately in parallel to a liquid crystal orientation direction of the liquid crystal layer. The plurality of linear portions of the second electrode are arrayed to have predetermined electrode widths and a predetermined electrode distance therebetween. An electrode distance Wrs of the plurality of linear portions in the reflective display portion is set smaller than an electrode distance Wts of the plurality of linear portions in the transmissive display portion. An electrode width Wre of each of the plurality of linear portions in the reflective display portion is set smaller than an electrode width Wte of each of the plurality of linear portions in the transmissive display portion. The relationship of (Wrs−1.5 μm)≦Wre≦(Wrs−0.5 μm) is satisfied in the reflective display portion and the relationship of (Wts−1.5 μm)≦Wte≦(Wts−0.5 μm) is satisfied in the transmissive display portion. | 10-01-2009 |
| 20090262288 | LIQUID CRYSTAL DISPLAY AND ELECTRONIC APPARATUS - A liquid crystal display includes a first substrate and a second substrate opposite to each other with a liquid crystal layer interposed therebetween, first and second electrodes provided on a side of the first substrate facing the liquid crystal layer to drive the liquid crystal layer, and a reflecting layer provided on a part of the side of the first substrate facing the liquid crystal layer. Each pixel region includes a reflective display region where light incoming from the second substrate is reflected by the reflecting layer toward the second substrate to perform display and a transmissive display region where light incoming from the first substrate is transmitted toward the second substrate to perform display. The liquid crystal layer has horizontal alignment in an initial alignment state. A first polarizing plate is provided on a side of the first substrate opposite the liquid crystal layer, the first polarizing plate having a transmission axis parallel or perpendicular to an alignment direction of the liquid crystal layer in the initial alignment state. A second polarizing plate is provided on a side of the second substrate opposite the liquid crystal layer, the second polarizing plate having a transmission axis perpendicular to the transmission axis of the first polarizing plate. A resin layer is provided on a side of the second substrate facing the liquid crystal layer, the resin layer having a first resin layer provided in the transmissive display region and a second resin layer provided in the reflective display region. The first resin layer is a λ/2 phase layer giving a phase difference of approximately ½ wavelength (wavelength: λ) with respect to visible light, and a slow axis of the first resin layer and the transmission axis of the first polarizing plate are disposed so as to be parallel or perpendicular to each other. The second resin layer is a λ/2 phase layer giving a phase difference of approximately ½ wavelength with respect to visible light, and a slow axis of the second resin layer is set in a direction intersecting the alignment direction of the liquid crystal layer. A step portion is provided between the first substrate and the resin layer in order to make the thickness of the liquid crystal layer in the reflective display region smaller than the thickness of the liquid crystal layer in the transmissive display region. A slope portion having a continuously changing thickness is provided in an end portion of the step portion. The slope portion is disposed in the transmissive display region. | 10-22-2009 |
| 20100066952 | LIQUID CRYSTAL DEVICE AND ELECTRONIC APPARATUS - A liquid crystal device includes: a liquid crystal layer which is sandwiched between a pair of substrates; a color filter layer has a first coloration layer for transmitting a first light and a second coloration layer for transmitting a second light; first electrodes has a first pixel electrode disposed on a first sub-pixel region corresponding to a planar region of the first coloration layer and a second pixel electrode disposed on a second sub-pixel region corresponding to a planar region of the second coloration layer; and second electrodes each of which faces each first electrode.

| 20090102960 | IMAGE PICKUP APPARATUS - An image pickup apparatus includes an optical system which forms an image of a shooting subject. A driving section drives the optical system. A focus operation section transmits a driving direction and a driving amount of the optical system on the basis of a manual operation. An image pickup element converts the image of the shooting subject formed by the optical system into a video signal. An evaluation section evaluates a focus condition of at least one area within a photographing field on the basis of the video signal from the image pickup element. An autofocus adjustment section selects an area which is determined to be focused as a result of the evaluation of the focus condition and drives the optical system to a position corresponding to the area determined to be focused. | 04-23-2009 |
| 20090237550 | FOCUS ADJUSTMENT APPARATUS AND IMAGE CAPTURING APPARATUS - A focus adjustment apparatus or an image capturing apparatus is provided with a system controller. The system controller calculates a correlation value between an image in a focus detection area when a focusing lens is located at a lens position apart by a predetermined distance from a lens position where a focus evaluation value reaches a peak value, to a close end side, and an image in a focus detection area when a focusing lens is located at a lens position apart by a predetermined distance from a lens position where a focus evaluation value reaches a peak value, to an infinity side, and determines a lens position corresponding to a peak value to be a focused lens position, when a correlation value calculated by the correlation value calculation unit is over a predetermined value. | 09-24-2009 |
| 20100060748 | IMAGE PICKUP APPARATUS AND IMAGE PICKUP CONTROL METHOD - When an image of a subject formed by an optical system is picked up using an image pickup device, charges obtained upon receiving light for the subject image are accumulated with a time difference for each scan line in the image pickup device. Concurrently, a characteristic of the optical system is modified to change a distance to the subject at which the image pickup device is in focus, for each horizontal scan line. | 03-11-2010 |
