Array substrate and liquid crystal display device

Abstract

The invention relates to an array substrate and a corresponding liquid crystal display device. The array substrate comprises a grid line, a data line, a shading transparent electrode and shading metaland is characterized in that the grid line and the data line are arranged in a crossed manner to define multiple pixel areas, and pixel electrodes are arranged in the pixel areas; the shading transparent electrode is vertically opposite to the data line, and projection of the data line on the shading transparent electrode falls into the shading transparent electrode; each shading metal is arranged along the edge of the corresponding pixel electrode; at least part of the data line and the shading metal vertically oppositely overlaps in an area, close a black matrix, of the shading transparentelectrode. By the array substrate and the liquid crystal display device, the pixel light leakage problem of the DBS technology is solved.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to an array substrate and a liquid crystal display device. Background technique [0002] The HVA (High Vertical Alignment) mode is a relatively advanced one among the VA (Vertical Alignment) modes, and is used by many manufacturers in the LCD industry to produce large-size LCD screens. The traditional HVA mode uses BM (black matrix) to shade the gate (gate) and data (data) lines of the pixel. BM) expression, referred to as DBS. [0003] Existing liquid crystal display panels generally include a TFT (thin film transistor) array substrate, a CF (color filter) substrate disposed opposite to the TFT array substrate, and a liquid crystal layer disposed between the TFT array substrate and the CF substrate. figure 1 It is a schematic top view of the existing DBS-designed array substrate structure, viewed from the substrate side of the TFT array substrate, for the convenience of dis...

but for figure 1 The area indicated by the middle box 10—the area where the light-shielding transparent electrode 13 is adjacent to the black matrix 16 instead of overlapping up and down, because this area is close to the gate electrode of the TFT, at the end of the pixel electrode 15 and the light-shielding metal 14, the electric field is relatively disordered, and the liquid crystal Easy to rotate disorderly, resulting in phase change of polarized light, and no BM shielding, resulting in light leakage
