Structure and manufacturing method of array colored film integrated type liquid crystal display panel

Abstract

The invention provides a structure and manufacturing method of an array colored film integrated type liquid crystal display panel. The method includes the steps that a color-shielding layer (30) is manufactured on a first protection layer (25), the portions, located above a grid (21) and a source / drain electrode (24), of the color-shielding layer (30) are removed through a wet etching process, and then a second protection layer (40) covering the color-shielding layer (30) and the first protection layer (25) is deposited; a pixel electrode (50) is formed on the second protection layer (40) and penetrates through a via hole (45) of the second protection layer (40) and the first protection layer (25) to be in contact with the source / drain electrode (24); then the region where the color-shielding layer (30) is removed through the wet etching process is filled with black matrix materials, a black matrix (60) and a spacer (70) located on the black matrix (60) and integrated with the black matrix (60) are manufactured at the same time through a slit mask, the aperture opening ratio can be increased, bubbles are avoided, meanwhile the mask is saved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for manufacturing an array color filter integrated liquid crystal display panel and its structure. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. Generally, a liquid crystal display panel is composed of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and...

Problems solved by technology

[0004] However, in the production process of the existing array color filter integrated liquid crystal display panel, holes need to be opened on the color resistance layer for electrically connecting the pixel electrodes to the source / drain electrodes of the TFT. On the one hand, opening holes on the layer will reduce the aperture ratio. On the other hand, opening holes on the color resist layer can easily hide gas. When the liquid crystal display panel encounters high temperature, vibration, or impact, the hidden gas will overflow and form air bubbles. (Bubble), occupying the position of the liquid crystal, causing abnormal display
