Abstract

The invention provides an array substrate, which comprises a plurality of sub-pixels and a first metal layer, wherein the plurality of sub-pixels are in array arrangement, and each sub-pixel is divided into a main area and a secondary area; in the main area, the first metal layer is provided with first longitudinal lines and a first lateral line; each longitudinal-row sub-pixel corresponds to at least one first longitudinal line; the first lateral line is arranged on one side, which faces the secondary area, of the main area, and all first longitudinal lines are vertically connected to the first lateral line; in the secondary area, the first metal layer is provided with second longitudinal lines and a second lateral line, wherein each longitudinal-row sub-pixel corresponds to one second longitudinal line; the second lateral line is arranged on one side, which faces the main area, of the secondary area; and all second longitudinal lines are vertically connected to the second lateral line. The array substrate aims to reduce intersections and corners in a pixel area through the reduction of the lateral line of a first common electrode, and the problems of light leakage, poor contrastratio and the like of the pixel under a dark state can be effectively eliminated.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to an array substrate. Background technique

[0002] Generally, in the pixel design and LCD manufacturing process, graphics are made on the first layer. In addition to the TFT gate, the common electrode (first common electrode) component of the array substrate will also be added, because its metal is opaque and shields the electric field. Therefore, it is also called "shading metal".

[0003] In the pixel design of common array substrates, the first common electrode is set on the first metal layer, and its main structure can shield the lateral electric field of the scanning line, which can be used to protect the pixel electrodes; while the main area is set as a grid-like first common electrode. The common electrode can also shield the coupling effect of the high-voltage and high-frequency hopping electric field of the data line on the pixel electrode, making the pixel volt...
