Manufacturing method of color filter substrate

Abstract

The invention provides a manufacturing method of a color filter substrate. The manufacturing method of the color filter substrate comprises the following steps of first, depositing a protective film of a metal material on a surface of an incoming substrate, and then enabling the surface, on which the protective film is formed, on the substrate to be in contact with a bearing platform in a subsequent manufacturing process, forming a black matrix, a color resistive layer, an outer coating layer and the like on another surface of the substrate, afterwards, removing the protective film on the surface of the substrate by using an acid solution of hydrochloric acid and the like before the substrate is thinned, finally, thinning the substrate, and completing the manufacturing of the color filter substrate, so as to obtain the color filter substrate. The protective film can effectively protect the surfaces of the substrate, and prevents devices from causing damage to the surfaces of the substrate to result in the generation of concave and convex points on the surface in a manufacturing process, thereby avoiding the further aggravation of the poorness of the concave and convex points when the substrate is thinned; the yield of display panels is promoted.

Description

technical field [0001] The invention relates to the field of manufacturing display panels, in particular to a method for manufacturing a color filter substrate. Background technique [0002] A liquid crystal display device (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Usually, the liquid crystal display panel consists of a color filter substrate (CFSubstrate, ColorFilterSubstrate), a thin film transistor array substrate (TFTArray Substrate, ThinFilmTransistorArraySubstrate), a liquid crystal (LC, LiquidCrystal) sandwiched between the color filter substrate and the thin film transistor array substrate, and a sealant (Sealant) Composition; its molding process generally includes: front-end array (Array) process (thin...

Problems solved by technology

[0005] Generally speaking, grinding can be used for poor Dimple, but the disadvantage of using grinding is that it increases the risk of grinding bright spots and insufficient stress (Fail), especially for large-size screens with relatively high stress requirements (such as 8.6 inches) , 10.1 inches, etc.)
