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.
Claims9
A liquid crystal display device of a latitudinal electric field type, comprising:
- a first substrate provided with a scan line for controlling a switching element connected to a pixel electrode and a data line, a common electrode arranged parallel to said pixel electrode via insulating film, and a common electrode wire connected to said common electrode and extended in a direction intersecting said data line;
- a second substrate disposed opposite said first substrate via liquid crystal layer;
- and
- a protruded spacer formed on at least one of said first substrate and said second substrate so as to fix a gap between said first substrate and said second substrate, said protruded spacer being located over at least one of said common electrode wire and said extended portion of said pixel electrode.
