Patent ID: 8537083

Claim:
A liquid crystal display device, comprising: pixels that are formed by a liquid crystal layer; display electrodes disposed across the liquid crystal layer; a counter electrode made of a transparent material, and which displays an image by applying a drive voltage to the liquid crystal layer, the drive voltage corresponding to a potential difference between each of the display electrodes and the counter electrode; a source voltage supplying part that supplies source voltages based on image signals to the display electrodes; a feedback voltage supplying part that outputs a feedback voltage corresponding to a potential in a virtually center area of the counter electrode; and a first common voltage supplying part that supplies the common voltage to at least one edge of the counter electrode, a second common voltage supplying part that compares the feedback voltage with a reference voltage, feedback controls the common voltage based on the result of the comparison, and supplies the thus controlled common voltage to the virtually center area of the counter electrode; wherein the feedback voltage supplying part comprises a first conductive wire, and one end of the first conductive wire is directly connected to the virtually center area of the counter electrode, the virtually center area is a horizontally center of the counter electrode located at the same distance from both horizontal edges of the counter electrode, and a vertically center of the counter electrode located at the same distance from both vertical edges of the counter electrode, the virtually center of the counter electrode is an area where a large pulsation of the common voltage occurs.
