Embodiment 1

[0019] In order to solve the above-mentioned technical problems, an embodiment of the present invention provides an array substrate, which has a protective layer above the array substrate, a spacer support area on the protective layer, and a charge transfer layer on the protective layer. layer, at least a part of the charge transfer layer is located in the spacer supporting area, and an electrostatic discharge unit is further arranged on the array substrate, and the charge transfer layer is electrically connected to the electrostatic discharge unit. Therefore, the static electricity generated by the friction between the spacer and the spacer support area can be transferred to the electrostatic discharge unit through the charge transfer layer to be released, and will not affect the orientation of the liquid crystal molecules around the spacer, thereby ensuring the display quality of the display panel.

[0020] Preferably, the charge transfer layer completely covers the spacer su...

Embodiment 2

[0032] Such as figure 2As shown, a display panel is provided in this embodiment, which includes an array substrate 100 and a color filter substrate 200 disposed opposite to each other, wherein the array substrate 100 adopts the array substrate in the first embodiment. A spacer 5 is formed on the color filter substrate 200, and the spacer 5 is arranged in contact with the charge transfer layer 1 on the array substrate 100, so that the static electricity generated by the friction between the spacer and the spacer support area on the array substrate can pass through The charge transfer layer 1 is transferred to the electrostatic discharge unit 10 to be released without affecting the orientation of the liquid crystal molecules 8 around the spacers 5, thereby ensuring the display quality of the display panel.

Embodiment 3

[0034] Based on the same inventive concept, this embodiment provides a method for manufacturing an array substrate, including:

[0035] A charge transfer layer electrically connected to the electrostatic discharge unit is formed on the protective layer, at least a part of the charge transfer layer is located in the spacer supporting area on the protective layer.

[0036] The electrostatic discharge unit and the charge transfer layer formed through the above steps enable the static electricity generated by the friction between the spacer and the support area of ​​the spacer to be released through the charge transfer layer to the electrostatic release unit, without affecting the liquid crystal molecules around the spacer The orientation of the display panel has an influence, ensuring the display quality of the display panel.

[0037] Preferably, the charge transfer layer completely covers the spacer supporting region.

[0038] Further, in order to increase the surface roughness...

Abstract

The invention relates to the technical field of liquid crystal display and provides an array substrate, a manufacturing method of the array substrate and a display panel. A charge transfer layer is arranged at a shock insulator object support area on the array substrate and a static electricity releasing unit electrically connected with the charge transfer layer is arranged, so static electricity generated at the shock insulator object support area and a shock insulator object can be released; the influence of the static electricity to the orientation of liquid crystal molecules around the shock insulator object can be overcome and the problems such as light leaking are solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate, a preparation method thereof, and a display panel. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in recent years and occupies a dominant position in the current flat panel display market. [0003] The main structure of TFT-LCD includes the array substrate and the color filter substrate of the cell, and the liquid crystal molecules filled between the array substrate and the color filter substrate. Data lines, gate lines, and common signal lines are formed on the array substrate, as well as pixel units defined by the data lines and gate lines. Each pixel unit includes a thin film transistor (Thin Film Transistor, TFT for short) and a transparent pixel electrode. Wherein, the common signal line and the gate...
