An array substrate of a display panel and a manufacture method thereof

Abstract

A method for manufacturing an array substrate of a display panel comprises the steps of providing a substrate, on which a thin film transistor and a connection electrode are formed; forming a first protection layer and a flat layer on the substrate, the flat layer comprising a first opening and second opening corresponding to the drain electrode of the thin film transistor and the connection electrode respectively; forming a common electrode, a second protection layer and a light resistance pattern layer which exposes the second protection layer disposed in the first opening and the second opening and corresponding to the common electrode; etching the second protection layer exposed by the light resistance pattern layer for forming a third opening, a fourth opening and a fifth opening; etching the first protection layer exposed by the third opening and the fourth opening for forming a sixth opening and a seventh opening and exposing the drain electrode and the connection electrode; and removing the light resistance pattern layer and forming a bridging electrode and a pixel electrode on the second protection layer.

Description

technical field [0001] The present invention relates to an array substrate of a display panel and a manufacturing method thereof, in particular to an array substrate of a display panel capable of reducing a photolithography and etching process (hereinafter referred to as PEP). Background technique [0002] Flat panel displays, such as liquid crystal displays, have replaced traditional cathode ray tube (CRT) displays and become the mainstream of displays due to their thinness, lightness, low radiation, and low power consumption. In the development of the display, it is constantly developing towards the direction of high resolution requirements. However, as the resolution increases, the number of thin film transistors (thin film transistor, TFT) on the panel also increases, so that the available space on the panel continues to shrink. At the same time, in order to improve the aperture ratio and the performance of the thin film transistor, the number of PEP is increased in the...

AI Technical Summary

Problems solved by technology

However, as the resolution increases, the number of thin film transistors (TFT) on the panel also increases, making the available space on the panel continuously shrinking

At the same time, in order to improve the aperture ratio and the performance of thin film transistors, the number of PEPs has been increased in the process design

However, the shrinking of the available space and the increase of the number of PEP lead to continuous increase in the difficulty and cost of process control, which is not conducive to the production and development of display panels. Therefore, the current manufacturing methods of displays all focus on reducing the number of PEP. development Goals
