20130222718 | DISPLAY DEVICE - A display device includes a display panel, a liquid crystal panel superimposed on the display panel for enabling naked-eye stereoscopic view by separating a left-eye image and a right-eye image displayed on the display panel, and a flexible wiring substrate attached to the liquid crystal panel. The liquid crystal panel has a substrate and a substrate opposed to each other. The substrate has a projection part that projects from the substrate. The flexible wiring substrate is attached to a surface of the projection part of the substrate at the substrate side. The substrate is formed to be thinner than the substrate and provided at a side of the display panel. | 08-29-2013 |
20130222719 | THREE-DIMENSIONAL DISPLAY DEVICE - A three-dimensional display device includes an image display panel that has an alignment mark and a parallax formation panel that has an alignment mark and separates a left-eye image and a right-eye image displayed on the image display panel to enable autostereoscopic vision. At least one of the image display panel and the parallax formation panel has a pair of substrates placed on top of each other, and the alignment mark is formed between the pair of substrates. | 08-29-2013 |
20130343021 | Display Device - A display device includes a display panel, a first film-like printed circuit board including a first terminal portion, the first film-like printed circuit board extending from one side of the display panel in a direction away from the display panel, a touch panel provided so as to be opposed to the display panel, and a second film-like printed circuit board including a second terminal portion, the second film-like printed circuit board extending from one side of the touch panel in the direction away from the display panel, the one side of the touch panel corresponding to a side parallel with and adjacent to the one side of the display panel. The first terminal portion and the second terminal portion are provided so that a connecting direction of the first or second terminal portions is different from a connecting direction of the second or first terminal portions. | 12-26-2013 |
20140036537 | Liquid Crystal Display Device - A backlight device includes a frame with a first opening having a first side, a second side, a third side, and a fourth side, a planar light source which is disposed in the first opening of the frame, a plurality of optical sheet groups which are disposed on the planar light source and include a first optical sheet group and a second optical sheet group, and an adhesive layer which has a second opening formed along the first, second, third, and fourth sides of the frame. The first optical sheet group is fixed to the frame via the adhesive layer at the second, third, and fourth sides of the frame, and the second optical sheet group is fixed to the frame at the first side of the frame and is not fixed to the frame at the second, the third, and fourth sides of the frame. | 02-06-2014 |
20140055691 | LIQUID CRYSTAL DISPLAY DEVICE - A mobile phone is provided which includes a liquid crystal display device in which a front window and a touch panel are bonded together with an adhesive sheet, wherein a logo having plural layers is formed on a back side of the front window. A touch-panel flexible wiring substrate is mounted to the touch panel. A plane distance between an end portion of the plural layers of the logo and an end portion of the touch panel is set to greater than zero. With this configuration, it is possible to prevent a peeling stress on the adhesive sheet, even if a thickness of the adhesive sheet is smaller than the sum of a thickness of the touch-panel flexible wiring substrate and a thickness of the logo. | 02-27-2014 |
20140063415 | LIQUID CRYSTAL DISPLAY DEVICE - In a liquid crystal display device, adjacent light-emitting elements of adjacent different groups are not connected in series but are arranged with an interval. Adjacent light-emitting elements of the same group are arranged with an interval shorter than the interval between the adjacent light-emitting elements of the adjacent different groups. The frame includes plural recesses recessed from an inner peripheral surface facing the light guide plate and recessed also from a surface opposite to the liquid crystal display panel. A protrusion is relatively formed between the adjacent recesses. The light-emitting elements of any one of the groups are housed in one of the recesses and the light-emitting elements of the plural groups are respectively housed in the plural recesses. A protrusion is positioned between the adjacent light-emitting elements of the adjacent different groups. | 03-06-2014 |
20140368468 | Liquid Crystal Display Device - A display device includes a display panel including a first surface, a second surface opposed to the first surface, and a side surface extending between the first surface and second surface, a frame fixed to the first surface of the display panel by a double-sided tape, and a capacitive touch panel adhered to the second surface of the display panel. The frame includes a first portion opposed to the first surface of the display panel, and a second portion surrounding the side surface of the display panel and opposed to a rear surface of the capacitive touch panel. The capacitive touch panel has a protruding end portion which protrudes beyond one end of the display panel. The protruding end portion overlaps the second portion of the frame, and a gap is delimited between the protruding end portion and the second portion of the frame. | 12-18-2014 |
