Embodiment Construction

[0027] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] see figure 1 , figure 2 and image 3 , an embodiment of the present invention provides a method of manufacturing a color filter, the method comprising:

[0029] 101. Forming a black matrix 22 on a transparent substrate 21;

[0030] The black matrix 22 can be formed on the transparent substrate 22 by coating, specifically, there is a certain interval between the black matrix 22;

[0031] 102. Form a photosensitive photoresist layer 33 on the transparent substrate 21 with the black matrix 22;

[0032] Specifically, taking the color-resist layer of a color filter including the three primary colors of red, green and blue as an example, the color-resist materials of the three primary colors of red, green, and blue can be arranged in sequence in each pixel; The transparent substrate 21 of the adhesive layer 33 is pre-baked, and then the cooling ...

Abstract

The invention discloses a method for making a color filter, a color filter and a display device, and relates to the field of display technology, in order to solve the problem of edge brightness and color unevenness and contrast of a liquid crystal display module caused by the color filter in the prior art Invented for poorer problems. The method for making a color filter includes: forming a black matrix on a transparent substrate; forming a photosensitive photoresist layer on the transparent substrate with the black matrix; arranging a reflector capable of reflecting light on the to-be-exposed The transparent substrate is formed on one side of the black matrix; the mask plate is arranged on the side of the transparent substrate to be exposed without the black matrix; and the exposure is performed from the side of the transparent substrate without the black matrix.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a color filter, the color filter and a display device. Background technique [0002] Color filters are important components in LCD displays. In a liquid crystal display, the strong light emitted by the backlight module is processed by a color filter to present a colorful picture. The structure of the color filter usually includes a transparent substrate, a black matrix fabricated on the transparent substrate, a color layer composed of three primary colors of red, green and blue, and a transparent conductive layer. [0003] The method of making a color filter in the prior art is usually as follows: firstly, a black matrix is ​​made on a transparent substrate to form intervals; and then the three primary colors of red, green and blue are arranged in sequence in each pixel of the color layer. Among them, the back exposure technology is used in the produ...
