Abstract

The invention relates to a thin film transistor liquid crystal display (TFT-LCD) array substrate and a manufacturing method thereof. The array substrate comprises a grid line and data lines which are formed on a substrate and define a pixel region, wherein a pixel electrode, a TFT and common electrodes are formed in the pixel region. The array substrate also comprises a black matrix which is prepared from conductive film materials and is connected with the common electrodes. The manufacturing method comprises the following steps: forming a graph comprising the grid line, the data lines, the pixel electrode and the TFT; and forming a graph comprising the common electrodes and the black matrix. The array substrate and the manufacturing method have the following beneficial effects: the black matrix can not only effectively shelter the light leakage region but also serve as the connection bus of the common electrodes by arranging the graph comprising the black matrix on the array substrate and connecting the black matrix with the common electrodes, thus effectively overcoming the technical defects of high production cost of the existing structure and common electrode delay.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display and a manufacturing method thereof, in particular to a thin film transistor liquid crystal display array substrate and a manufacturing method thereof. Background technique [0002] In Thin Film Transistor Liquid Crystal Display (TFT-LCD) products, Advanced-SuperDimensional Switching (Advanced-SuperDimensional Switching; AD-SDS) is a new technology that can improve LCD image quality in recent years. One of the technologies, it can realize the requirements of high penetration and large viewing angle at the same time. AD-SDS forms a multi-dimensional spatial composite electric field through the parallel electric field generated by the edge of the pixel electrode in the same plane and the vertical electric field generated between the pixel electrode layer and the common electrode layer, so that all the pixels between the pixel electrodes in the liquid crystal cell, directly above the el...
