Patent ID: 8358385

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate which is arranged to face the first substrate; a liquid crystal layer which is provided between the first substrate and the second substrate; a thin film transistor which is formed on a surface side of the second substrate facing the first substrate; a pixel electrode which is formed on the surface side of the second substrate facing the first substrate, and which is connected to the thin film transistor; a scanning line which supplies a gate signal to the thin film transistor; a signal line which supplies a data signal to the thin film transistor; an insulating film which covers the thin film transistor, the pixel electrode, the scanning line, and the signal line; and a common electrode which is arranged on the insulating film, wherein the pixel electrode has a pair of first short side edges extending in a first direction, and a pair of first long side edges extending a second direction perpendicular to the first direction, and wherein the common electrode has a plurality of first slits in a portion overlapping with the pixel electrode, the first slits having a pair of second short side edges which extend in the first direction and which are shorter than the pair of the first short side edges, and a pair of second long side edges which extend in the second direction and which are longer than the pair of the first long side edges such that the pair of the second short side edges are arranged so as to be not overlapped with the pixel electrode.
