Abstract: A reliability of seal portion of a liquid crystal display device can be improved by the following structure. A liquid crystal display device includes: a TFT substrate which includes a display region and a terminal part, and has an inorganic insulating film formed on an organic passivation film and an alignment film formed over the inorganic insulating film; a counter substrate, the TFT substrate and the counter substrate bonded together by a sealing material formed at a seal part surrounding the display region; and a liquid crystal sealed inside. At the seal part, a transparent conductive oxide film is formed between the inorganic insulating film and the alignment film. The transparent conductive oxide film exists inside an edge of the TFT substrate and hence, the edge of the TFT substrate is free of the transparent conductive oxide film.

Abstract: To prevent dark unevenness at the corner portion of a screen, a provided is a liquid crystal display including a first pixel formed with a pixel electrode at a first angle in a Y-direction, wherein the pixel electrodes of top, bottom, left, and right adjacent pixels to the first pixel are at a second angle in a Y-direction. The absolute value of the first angle is equal to the absolute value of the second angle, and a sign of the first angle is opposite to a sign of the second angle The rotation direction of a liquid crystal when a voltage is applied to the pixel electrode is in the opposite directions between the adjacent pixels. Thus, it is possible to prevent ions included in the liquid crystal from flowing on the peripheral portion of a display region to prevent dark unevenness at the corner portion of the screen.
