Abstract:
A liquid crystal display includes an array of pixels. Each pixel is divided into a first sub-pixel and a second sub-pixel, and different data voltages are separately applied to (or evolved at) the two sub-pixels, thereby enhancing the lateral side visibility. Each sub-pixel includes a sub-pixel electrode (connected to the drain electrode of a sub-pixel's switching element) overlapped with the sub-pixel's storage electrode. A first predetermined voltage is applied to the first sub-pixel and second predetermined voltage is applied the second sub-pixel, and thus the first sub-pixel electrode may receive a voltage lower than the voltage of the second sub-pixel electrode. The first sub-pixel electrode may be larger in area than the second sub-pixel electrode. The overlapping area between the first drain electrode and the storage electrode of a first sub-pixel may be larger than the overlapping area between the drain electrode and the storage electrode of a second sub-pixel. Thus the kickback voltage of the first sub-pixel may be substantially the same as the kickback voltage of the second sub-pixel.
