Array substrate of liquid crystal display device

Abstract

The invention relates to an array substrate of a liquid crystal display device, comprising grid lines, data wires and pixel electrodes which are formed on the substrate, wherein the pixel electrodes are arranged in a pixel area limited by the grid lines and the data wires, and concave and convex shapes capable of generating liquid crystal disclinations are arranged on the edges of the pixel electrodes near to the data wires, i.e. concave and convex shapes such as rectangular gaps, triangular gaps, trapezoidal gaps or arch-shaped gaps are arranged on one side of the pixel electrodes near the data wires at interval. As for the array substrate of the liquid crystal display device, the liquid crystal disclinations are formed on the edge regions of the pixel electrodes near to the data wires, thus the edge regions between the pixel electrodes and the data wires become light proof areas by the light proof property of the liquid crystal disclinations, and the problem of light leakage existing in the prior liquid crystal display device is solved; and further, a black matrix on a color film substrate can be designed to be narrower than the black matrix of the prior art, thus the aperture opening ratio of a liquid crystal display is effectively increased and the product quality is improved.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to an array substrate of the liquid crystal display device. Background technique [0002] The main structure of a liquid crystal display (Liquid Crystal Display, LCD) includes a cell-aligned array substrate and a color filter substrate. Figure 5 is a plan view of a prior art liquid crystal display, Figure 6 for Figure 5 Middle A-A sectional view. like Figure 5 , Figure 6 As shown, the array substrate includes a gate line (not shown), a data line 10 and a pixel electrode (indium tin oxide, ITO for short) 20 formed on the substrate, and the data line 10 is arranged between the two pixel electrodes 20; the color filter The substrate includes a colored resin (not shown) formed on the substrate and a black matrix 30 for shielding gate lines, data lines and gaps between them and pixel electrodes. [0003] However, in actual production and use, when the periphery of the color filt...

Problems solved by technology

However, increasing the width of the black matrix will reduce the aperture ratio and reduce product quality, while increasing the lamination margin will be limited by the process and will lead to an increase in product cost
