Abstract
A liquid crystal display comprises an array substrate in which a common electrode, a pixel electrode, a scanning signal line, a video signal line and a semiconductor switching element are provided, an opposed substrate, and a liquid crystal layer interposed between the array substrate and opposed substrate. The line width of at least either the common electrode or the pixel electrode is larger than the distance between the common electrode and the pixel electrode. The film thickness of at least one of the common electrode and the pixel electrode is larger than the thickness of at least either the scanning signal line or the video signal line. As a result, an inplane electric field liquid crystal display having a wide viewing angle, high-speed response, and high image quality such as high luminance is provided.
