Abstract

A liquid crystal display device includes a plurality of pixels arranged in a matrix mode. Each pixel contains at least a first sub-pixel and a second sub-pixel, each of the first or the second sub-pixel includes a liquid crystal capacitor and a storage capacitor, and the liquid crystal capacitance and the storage capacitance ratio of the first sub-pixel is less than that of the second sub-pixel, wherein, in a first pixel and a second pixel of all the pixels, the first sub-pixel of the first pixel is in dislocation setting with the first sub-pixel of the second pixel, and the second sub-pixelspixel of the first pixel is in dislocation setting with the second sub-pixel of the second pixel.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a pixel distinguishing method of the liquid crystal display device and a driving method of the liquid crystal display device. Background technique [0002] Liquid crystal display device is one of the common flat-panel displays at present. It has the advantages of high resolution, light weight, thin thickness, and low power consumption. Therefore, the use of liquid crystal display devices is becoming more and more common at present. In addition to being used as a computer display device, it can also be used as a touch screen for man-machine interface, and can also be used as a TV in combination with a video system. [0003] However, although liquid crystal display devices are becoming more and more popular, there are still some technical problems that need to be further solved, such as the problem of wide viewing angle. As mentioned above, the viewing angle of a liquid c...
