Patent ID: 8384703

Claim:
A liquid crystal display device comprising: a substrate; pixels which are formed on the substrate; a first counter electrode signal drive circuit which is arranged on one side of a region where the pixels are formed; a second counter electrode signal drive circuit which is arranged on the other side of the region where the pixels are formed; a plurality of counter electrode portions which are provided corresponding to the pixels; and a plurality of counter electrode signal lines which are made conductive with the counter electrode portions, extend in the X direction, are arranged parallel to each other in the Y direction which intersects with the X direction, and are connected to the first counter electrode signal drive circuit or the second counter electrode signal drive circuit wherein the plurality of counter electrode signal lines include first and second counter electrode signal lines which are electrically connected with the first counter electrode signal drive circuit and which are not electrically connected with the second counter electrode signal drive circuit and third and fourth counter electrode signal lines which are electrically connected with the second counter electrode signal drive circuit and which are not electrically connected with the first counter electrode signal drive circuit; and wherein during an arbitrary 1 frame period, the first counter electrode signal drive circuit applies a first voltage to the first counter electrode signal lines and a second voltage to the second counter electrode signal lines, and the second counter electrode signal drive circuit applies a first voltage to the third counter electrode signal lines and a second voltage to the fourth counter electrode signal lines.
