ABSTRACT:
An in-plane switching mode LCD device includes a shield common electrode having a protrusion protruding from side edges of a drain line, and a pair of light shield films sandwiching therebetween the drain line and having an overlapping portion overlapping the protrusion. The shield common electrode shields the electric field from the drain line, and the light shield films improve the contrast ratio of the LCD device.
