Abstract

An array substrate, a manufacturing method, and a liquid crystal display panel, wherein the array substrate includes: a substrate; a TFT array formed on the substrate, the TFT array includes a plurality of TFTs arranged in an array; a first insulating layer covering the TFT array; a flat layer covering the first insulating layer; a common electrode formed on the flat layer; a second insulating layer covering the common electrode; a third insulating layer covering the second insulating layer; a plurality of pixel electrodes formed on the third insulating layer , each pixel electrode is connected to a conductive electrode of the corresponding TFT through a contact hole, each pixel electrode has a comb-like structure with electrode strips and slits, and the third insulating layer is on the electrode strip corresponding to each pixel electrode The remaining area outside the position is etched away to expose the second insulating layer below, wherein the third insulating layer and the second insulating layer are made of different materials, and the etching selectivity ratio between the third insulating layer and the second insulating layer is greater than 1. The film thickness of the second insulating layer is smaller than the film thickness of the third insulating layer.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate, a manufacturing method and a liquid crystal display panel. Background technique [0002] With the development of display technology, liquid crystal display panels (Liquid Crystal Display, LCD) are more and more popular due to their advantages of lightness and low radiation. The liquid crystal display panel includes a color filter substrate (color filter, CF) and an array substrate (TFT array substrate) opposite to each other, and a liquid crystal layer (LC layer) sandwiched between them. [0003] When the liquid crystal display panel is working, by applying the driving voltage and the common voltage to the pixel electrode and the common electrode respectively to generate an electric field between the liquid crystal layer, the deflection direction of the liquid crystal molecules will change with the difference between the applied driving voltage ...
