Abstract

The present invention relates to a FFS type TFT-LCD array substrate and a manufacturing method thereof, the array substrate comprises grid wires and data lines arranged on the substrate and defining a pixel area in which a pixel electrode, a thin film transistor, and a common electrode forming an edge electric field together with the pixel electrode are formed. The array substrate further comprises a black matrix prepared by metal thin film materials, and the black matrix is connected with the common electrode. The manufacturing method comprises forming the figures of the grid wires, the data wires, the pixel electrode and the thin film transistor; forming the figures of the common electrode and the black matrix which is prepared by metal thin film materials and connected with the common electrode. According to the invention, the figure of the black matrix is arranged on the array substrate and the black matrix is connected with the common electrode, which makes the black matrix block a light leak area effectively, and serve as a connection bus of the common electrode. The invention can effectively solve the problems of high production cost of present structure and the technical defect of the delay of the common electrode.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display and a manufacturing method thereof, in particular to an FFS type TFT-LCD array substrate and a manufacturing method thereof. Background technique [0002] In Thin Film Transistor Liquid Crystal Display (TFT-LCD) products, Fringe Field Switching (FFS) is one of the technologies that can improve LCD image quality in recent years. At the same time, the requirements of high penetration and large viewing angle are achieved. At present, the main structure of the FFS type TFT-LCD in the prior art includes an array substrate and a color filter substrate that are boxed together and the liquid crystal is sandwiched between them. The array substrate is formed with gate lines, data lines, pixel electrodes, thin film transistors and bar The common electrode of the shape structure, the color resin pattern and the black matrix pattern are formed on the color filter substrate, and the black matrix...
