Abstract

The invention relates to an array substrate of a capacitance type liquid crystal display device on a grid line, comprising a display area, a non-display area and a lead wire. Pixels with the number of M*N are arranged in the display area which is provided with grid lines from No.0 to No.N, and the M and the N are integers; the non-display area is arranged at the periphery of the display area, and the first side of the non-display area is provided with grid input ends which correspond to the grid lines from No.0 to No.N one by one and are respectively connected with the grid lines; the lead wire extends in the non-display area and is used for connecting with the last grid input end and the No.0 grid line. In the first embodiment of the invention, pulse voltage which is the same as the pulse voltage of the No.N grid line is provided for the No.0 grid line to ensure that the first row of pixels input high level only when the No.N grid line is charged, and the capacitance of the first row of pixels is same with that of other rows of pixels, thereby the defect caused by different capacitances between the first row of pixels and other rows of pixels in the prior art is overcome, the liquid crystal display device with high picture quality is realized and the quality of the liquid crystal display device is effectively improved.

Description

technical field [0001] The invention relates to a liquid crystal display device with high picture quality, in particular to a liquid crystal display device which improves the picture quality of the first row of pixel electrodes. Background technique [0002] The liquid crystal display device is a main flat display device, which is mainly composed of an array substrate and a color filter substrate. The liquid crystal located between the array substrate and the color filter substrate is arranged with the property of an electric field to realize the screen display. In order to keep the liquid crystal in a certain arrangement state in the pixel, the pixel capacitance is used to keep the pixel in a short constant electric field. The pixel capacitor is mainly composed of a liquid crystal capacitor and a storage capacitor, that is, pixel capacitor = liquid crystal capacitor + storage capacitor. [0003] Now there are two ways to realize the storage capacitor, one is to form a stor...
