Array substrate of LCD

Abstract

The invention relates to an array substrate of an LCD. The array substrate comprises a substrate which is provided with a plurality of grid lines and data lines which cross each other to define pixel areas; each pixel area is provided with a pixel electrode, wherein, shielding strips are arranged in parallel just below the data lines, and the width of the shielding strips is greater than that of the data lines. The shielding strips are connected with the data lines through holes. By arranging shielding strips which are wider than the data lines in parallel just below the data lines, the array substrate effectively avoids the light leakage that possibly occurs while flapping a panel.

Description

technical field [0001] The invention relates to an array substrate, which belongs to the field of manufacturing liquid crystal display devices. Background technique [0002] The core component used in the manufacturing process of a liquid crystal display (Liquid Crystal Display, hereinafter referred to as LCD) is a liquid crystal display panel composed of an array substrate and a color filter substrate. Such as figure 1 As shown in FIG. 1 , is a schematic diagram of a cross-sectional structure of a liquid crystal display panel in the prior art in the direction of data lines. The array substrate includes a first substrate 1, on which shielding strips 2, gate lines (not shown in the figure), data lines 3 and pixel electrodes Indium Tin Oxide (Indium Tin Oxide, hereinafter referred to as ITO) 4 are arranged; The film substrate includes a second substrate 5 on which a black matrix (Black matrix, BM for short) 6 and a color resin (Color Resin) are arranged. When the liquid cry...

AI Technical Summary

Problems solved by technology

When the liquid crystal display panel is tapped, the alignment of the color filter substrate and the array substrate is distorted, that is, the black matrix 6 and the data line 3 are dislocated and moved, causing the light between the shielding strip 2 and the data line 3 to leak out, resulting in light leakage. , resulting in the appearance of water ripples (TouchMura), leading to the result of reducing the performance of the left and right viewing angles, such as figure 2 shown

[0003] In order to solve the above-mentioned problems, methods such as increasing the width of the black matrix and increasing the width of the shielding strips are usually adopted in the prior art, but the above-mentioned technical solutions not only cannot completely prevent the occurrence of light leakage caused by the offset of the black matrix when the liquid crystal display panel is tapped, And it will also have the negative impact of reducing the opening ratio
