Problems solved by technology

But also because the dye is a small molecule, some problems are prone to occur in the color filter manufacturing process. The most common is the "floating color" caused by the dye precipitation, that is, the thermal movement of molecules due to the thermal process in the color filter manufacturing process Diffuse contamination of adjacent layers or pixels

[0072] see Figure 5 , corresponding to the first embodiment of the present invention, the present invention is also a color filter, including a substrate 1, a color resist layer 2 and an inorganic barrier layer 3;

[0073] The color-resist layer 2 includes a first color-resist 20 , a second color-resist 30 , and a third color-resist 40 arranged repeatedly along the surface of the substrate 1 ;

[0074] The inorganic barrier layer 3 includes a first inorganic barrier layer 50 covering the first color resistance 20, and the first inorganic barrier layer 50 connects the first color resistance 20 with the second color resistance 30 and the third color resistance. 40 apart.

[0075] Wherein, the material of the color-resisting layer 2 is a mixed color-resisting material including dyes and pigments, and the colors of the first color-resisting 20, the second color-resisting 30, and the third color-resisting 40 are different. Due to the small molecule properties of dyes, the first ...

Abstract

The invention provides a making method of a color filter and the color filter. The method comprises a step of making a color barrier layer on a substrate and a step of making an inorganic blocking layer. In the step of making the color barrier layer, first color barriers, second color barriers and third color barriers are formed in turn, wherein the first color barriers, the second color barriersand the third color barriers are sequentially and repeatedly arranged along the surface of the substrate. In the step of making the inorganic blocking layer, a first inorganic blocking layer coveringthe first color barriers is formed after the formation of the first color barriers and before the formation of the second color barriers. By setting the inorganic blocking layer to separate differentcolor barriers, the diffusion pollution between different color barriers can be avoided, and the display effect can be guaranteed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a color filter and the color filter. Background technique [0002] With the development of display technology, liquid crystal display (Liquid Crystal Display, LCD) and organic light emitting diode display (Organic Light Emitting Display, OLED) and other flat display devices have high image quality, power saving, thin body and wide application range, etc. Advantages, and are widely used in various consumer electronics products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, desktop computers, etc., and become the mainstream of display devices. . [0003] A color filter (Color Filter, CF) is an important component for providing color in liquid crystal displays and white OLED display devices. The color layer of a common color filter mainly includes red, green, and blue parts, and the target color dis...
