| 20080296583 | Display Device And Manufacturing Method of The Same - A display device includes a capacitive element configured so that a portion of a semiconductor layer which is made conductive constitutes one electrode, an insulation film which covers the semiconductor layer constitutes a dielectric film, and a conductive layer which includes a portion which is formed over the insulation film and is overlapped to the one electrode constitutes another electrode. The conductive layer has an extension portion which extends outside of a region where the semiconductor layer is formed from the inside of the region where the semiconductor layer is formed, and is formed over the insulation film. The insulation film has, in a region where the insulation film is overlapped to both the semiconductor layer and the extension portion of the conductive layer, a film thickness which is larger than a film thickness at a portion thereof which is overlapped to the one electrode. | 12-04-2008 |
| 20090073149 | Display device - The gate electrode is formed above the polycrystalline semiconductor layer through the gate insulating film. The polycrystalline semiconductor layer includes a first region overlapping with the gate electrode in plan view. The first region is sandwiched between the second region and the third region. The second region of the polycrystalline semiconductor layer includes a first impurity diffusion region and two second impurity diffusion regions opposite in conductivity type to the first impurity diffusion region. The first region and the first impurity diffusion region are in contact with each other at a first boundary. The first region and the two second impurity diffusion regions are in contact with each other at second boundaries. The two second impurity diffusion regions sandwiching the first impurity diffusion region are provided along the gate electrode. Thus, a leak current is suppressed. | 03-19-2009 |

| 20100321283 | LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD FOR SAME - A liquid crystal display device with a higher aperture ratio is provided. According to one embodiment of the present invention, second color filters are formed so as to overlap with first color filters when adjacent color filters having different colors are formed on the TFT substrate side, so that the angle of the first tapers where said first color filters overlap and the angle of the second tapers where said second color filters overlap are set to 45° or more and 90° or less. | 12-23-2010 |
| 20110001910 | LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device according to the invention includes a first substrate, on a surface of which are formed: a first color film which has a color other than black, and one portion of which configures a first pixel; a second color film, one portion of which configures a second pixel adjacent to the first pixel; a third color film, at least one portion of which configures a third pixel; and a fourth color film, a second substrate, and a liquid crystal layer sandwiched between the first substrate and second substrate, wherein the first color film and second color film have a first overlapping portion in which they overlap each other in the boundary between the first pixel and second pixel, and the fourth color film, being formed on the first overlapping portion, configures a post spacer which defines the space between the first substrate and second substrate. | 01-06-2011 |
| 20120087003 | ELECTROPHORETIC DISPLAY DEVICE - A pixel is formed by sealing an insulating liquid and floating particles in an area defined by a first substrate, a second substrate and partitions. The width of the partition has to be reduced in order to improve the pixel brightness by enlarging a flat electrode. In this case, the height of the partition has to be reduced for retaining the mechanical strength. If the height of the partition is reduced, an area of the partition electrode becomes small, thus failing to retain the memory effect. The planar surface of the partition is then formed into a zigzag shape so as to increase the area of the partition electrode. | 04-12-2012 |
| 20120088325 | MANUFACTURING METHOD OF DISPLAY DEVICE - Disclosed is a manufacturing method of a liquid crystal display device where first color filters, second color filters and third color filters which are formed adjacent to each other are provided, the first color filter and the second color filter are patterned in such a manner that one edge portion of the second color filter overlaps an edge portion of the first color filter, and the second color filter and the third color filter are patterned in such a manner that an edge portion of the third color filter overlaps the other edge portion of the second color filter wherein in an exposure step for patterning the second color filter, an exposure quantity in a region corresponding to one edge portion and an exposure quantity in a region corresponding to the other edge portion differ from each other. | 04-12-2012 |
