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
The present invention relates to the manufacture field of display floater, particularly relate to the manufacture method of a kind of color membrane substrates.
Background technology
Liquid crystal indicator (LCD, LiquidCrystalDisplay) has that fuselage is thin, power saving, the many merits such as radiationless, be widely used. Liquid crystal indicator major part on existing market is backlight liquid crystal indicator, and it includes display panels and backlight module (backlightmodule). Usual display panels is by color membrane substrates (CFSubstrate, ColorFilterSubstrate), thin-film transistor array base-plate (TFTArraySubstrate, ThinFilmTransistorArraySubstrate) liquid crystal (LC, LiquidCrystal) between color membrane substrates and thin-film transistor array base-plate and sealing frame glue (Sealant) composition, it are sandwiched in; Its moulding process generally comprises: leading portion array (Array) processing procedure (thin film, gold-tinted, etching and stripping), stage casing become box (Cell) processing procedure (TFT substrate and CF baseplate-laminating) and back segment module group assembling processing procedure (driving IC and printed circuit board (PCB) pressing); Wherein, leading portion Array processing procedure mainly forms TFT substrate, in order to control the motion of liquid crystal molecule; Stage casing Cell processing procedure mainly adds liquid crystal between TFT substrate and CF substrate; Back segment module group assembling processing procedure mainly drives the integration of IC pressing and printed circuit board (PCB), and then drives liquid crystal molecule to rotate, and shows image.
CF substrate is LCD for realizing the main devices of colored display, and its basic comprising generally includes: glass substrate, black matrix" (BlackMatrix, BM), colored color blocking layer etc. The light that backlight sends incides CF substrate through the modulation of liquid crystal molecule, the filtration of the red color resistance of color blocking layer, green color blocking and the blue color blocking of being enameled by CF substrate, show red respectively, green, blue three kinds of light, the light of the respectively transmitted corresponding color wave band of color blocking of different colours, thus realizing the colored display of display.
The development trend increasingly thinner for complying with liquid crystal display, the also progressively thinning of the thickness of the glass in current TFTLCD display floater. Generally after completing the processing procedures such as Array/CF/Cell, glass to be carried out thinning process. The sags and crests of glass surface, is called Dimple. The Dimple of CF substrate-side is due to the naked eyes directly facing beholder, so namely diameter (��) 1.5 ��m is considered bad, need to carry out demoting or reprocessing. And the main cause that Dimple produces is, in Array/CF/Cell processing procedure, plummer (Stage) surface irregularity or roller (Roller) are unsmooth, glass surface is caused to there is less sags and crests, in thinning process, due to the erosion of thinning liquid, make little sags and crests, become be relatively large in diameter, sags and crests that the degree of depth is bigger.
Generally speaking, milled processed can be used for Dimple is bad, but adopting the shortcoming of milled processed is the risk of risk and the understrressing (Fail) that improve and grinds broken bright spot, especially for the higher large scale screen of stress requirement (such as 8.6 cun, 10.1 cun etc.).
