Abstract: In order to increase the transmittance around a pixel and to increase the brightness of the screen in an IPS mode liquid crystal display device, a pixel electrode with a slit is formed on a common electrode through an interlayer insulating film. An opening is formed in the common electrode on the outside of the end portion of the pixel electrode as seen in a plane view. Because of the presence of the opening, the electric field lines from the end portion of the pixel electrode reach the layer above the liquid crystal layer and reach further away from the end portion of the pixel electrode, so that it is possible to increase the control ability to the liquid crystal around the pixel. As a result, the pixel transmittance can be increased as a whole and the brightness of the screen can be increased.

Abstract: Each of branch portions of a pixel electrode and inclined portions of data lines extends in a direction different from an x direction and a y direction in a pixel region and inclined with respect to the y direction. Further, a liquid crystal layer is orientated in a direction different from the x direction and the y direction in the pixel region and inclined with respect to the y direction.
