Abstract
In an active matrix liquid crystal display device of a latitudinal electric field type, i.e., of an In-Plane-Switching type, a protruded spacer is formed on one of a color filter substrate and a TFT substrate, and the spacer is positioned only at a location over a common electrode wire or over a portion of a pixel electrode extended over a gate electrode wire, to thereby reduce the occurrence of a long-term afterimage phenomenon.
