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.

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.
