ABSTRACT:
An active matrix liquid crystal display improves its contrast by suppressing irregularity of an alignment film caused by video lines thereby reducing reverse regions on a display electrode. The active matrix liquid crystal display has first and second opposite substrates, a video line, an active element and a display electrode which are directly or indirectly formed on the first substrate, and an alignment film which is formed on or above the video line, the active element and the display electrode. The alignment film is so formed that its surface is at an angle of inclination of not more than 10.5.degree. with respect to the display electrode surface between the video line and the display electrode.
