Abstract

This invention relates to a manufacturing method for the pixel structure of an edge field switch LCD including: forming a patternized first conduction layer containing data lines and grid on a base board, forming a first insulation layer covering said first conduction layer on the board, forming a patternized semiconductor layer on the first insualtion layer of the grid, forming a patternized second conduction layer containing a source, a drain and grid lines, forming a pixel electrode connected with the drain and covering the display region, forming a second insulation layer, patternizing said second insulation layer and said first insulation layer and a third conduction layer containing data line connecting electrode, grid line connecting electrode and a common electrode.

Description

technical field [0001] The present invention relates to a pixel structure of a liquid crystal display and a manufacturing method thereof, in particular to a pixel structure of a fringe field switching (Fringe Field Switching, FFS) liquid crystal display and a manufacturing method thereof. Background technique [0002] Among the current display products, liquid crystal displays are widely used and have gradually become the mainstream in the market. However, in terms of image performance of liquid crystal displays, there are still problems such as slow response speed and low aperture ratio. In order to increase the response rate and aperture ratio of the liquid crystal display, there is known a fringe field switching liquid crystal display (FFS-LCD), which is different from the general plane switching liquid crystal display (In-Plane Switching Liquid Crystal Display, IPS). Compared with the fringe field switching liquid crystal display, it has a higher aperture ratio, better o...
