Abstract: According to one embodiment, a liquid crystal display device includes a first area, second area, liquid crystal layer, and a plurality of pixels. Each subpixel includes an opening area including a first opening area and a second opening area. The pixels include a first pixel positioned in the first area and a second pixel positioned over a boundary of the first area and the second area. The opening area of the second pixel is smaller than the opening area of the first pixel when opening areas of subpixels of same color are compared. An each imaginary line showing the boundary of the first opening area and the second opening area is a same straight line.

Abstract: A liquid crystal display device includes: a TFT substrate including a TFT, an organic passivation film formed to cover the TFT, and an alignment film; and a counter substrate including a spacer and an alignment film. The TFT substrate and the counter substrate are bonded with a sealing material in a seal portion, with a liquid crystal interposed between the two substrates. A wall-like structure is formed in the seal portion of the counter substrate, in a direction parallel to a side of the counter substrate. A concave portion of the organic passivation film is formed at a position corresponding to the wall-like structure of the TFT substrate, in a direction parallel to the side of the TFT substrate. With this structure, a gap between the wall-like structure and the TFT substrate is increased to facilitate the movement of the sealing material before curing, to form the sealing material uniformly.

Abstract: A liquid crystal display device is provided in which color unevenness can be reduced and inhibited in the peripheral display area even when the display device has a narrow frame. In the liquid crystal display device, liquid crystal sandwiched between a TFT substrate and a CF substrate and sealed by a seal is disposed in a frame portion. The CF substrate has a BM, a color resist film, an OC, an alignment film, and a wall that inhibits the alignment film from expanding outward. In the area where the wall is disposed, the BM and color resist film on the CF substrate are removed.

Abstract: A liquid crystal display device includes a thin film transistor substrate, a counter substrate that faces the thin film transistor substrate, a liquid crystal composition that is arranged between the thin film transistor substrate and the counter substrate, an oriented film that arranges orientation of the liquid crystal composition contacting with the thin film transistor substrate, a seal material that seals the liquid crystal composition between the two substrates, and a driver circuit. The driver circuit has a light transmission area that is formed inside of the driver circuit, and is higher in light transmittance than an area in which a non-transparent conductive film forming the driver circuit is formed, and a high sealing property area in which the seal material and an insulating film come into direct contact with each other between the light transmission area and an outer edge of the thin film transistor substrate.
