Abstract

The invention relates to an array substrate of a liquid crystal display device, comprising a substrate, a grid line arranged on the substrate, a data wire intersected with the grid line, a thin film transistor which is electrically connected with the grid line and the data wire, and a pixel electrode which is electrically connected with the thin film transistor and positioned in an area defined by a crossed array of the grid line and the data wire; a section difference supplementation layer is arranged between the substrate and the grid line; and the section difference supplementation layer which corresponds to the data wire is provided with a first groove. By the first groove arranged on the section difference supplementation layer, the array substrate reduces the height of the data wire area and ensures that the height of the data wire area is equal to the height of the pixel area, thereby overcoming the defect of unfavorable friction of an oriented film on the surface of the prior array substrate.

Description

technical field [0001] The invention relates to an array substrate of a liquid crystal display device, in particular to an array substrate of a liquid crystal display device with high rubbing resistance. Background technique [0002] A liquid crystal display device is a main flat display device. With the technical progress of the liquid crystal display device, the performance of the liquid crystal display device is gradually improved, such as viewing angle performance, contrast ratio, response performance and the like. Now, in order to meet higher display requirements, the driving mode of the liquid crystal display device has been increased from 60Hz to 120Hz. The 60Hz driving method is a display method of refreshing 60 pictures per second, and the 120Hz driving method is a display method of refreshing 120 pictures per second. This method can improve the display effect of the liquid crystal display device. However, with the resistance of the current gate lines and data lin...
