Abstract
An OCB (optically compensated bend)-type liquid crystal display device is provided, which possesses high serviceability by suppressing disturbances of the liquid crystal molecules due to nearby electric fields or irregularities of the orientation surface. The OCB-type liquid crystal display device, formed by assembling an active matrix substrate, which comprises a plurality of rectangular pixel regions, each of which is surrounded by one of a plurality of a scanning lines arranged in parallel and one of a plurality of signal lines crossing said plurality of scanning lines through an insulating layer and each of which comprises a pixel electrode and a thin film transistor, and a transparent substrate provided with a common electrode, inserting a liquid crystal therebetween, and the opposing surface of the active matrix substrate and the opposing surface of the transparent substrate are treated so as to have the same orientation directions, wherein said pixel electrode is formed in a closer layer than that of the signal lines.
