Abstract

The invention discloses a color film substrate and a display device. The color film substrate comprises a base layer, a black matrix layer and a plurality of pixel units. Each pixel unit comprises a plurality of sub-pixels, and each sub-pixel is correspondingly provided with a color resistance layer. A plurality of even pixel units form an arrangement period and are provided with at least one pairof two adjacent pixel units, in the two adjacent pixel units, the arrangement sequence of the color resistance layers of one pixel unit is opposite to the arrangement sequence of the color resistancelayers of the other pixel unit, and in the adjacent pixel units, at least one pair of color resistance layers are the same in color. The color film substrate has the technical effects that the line width of the color film substrate is increased, and the production cost is saved.

Description

technical field [0001] The invention relates to the display field, in particular to a color filter substrate and a display device. Background technique [0002] With the improvement of display resolution requirements, for example, VR products require a resolution of 800-100ppi, which puts forward extremely high demands on the display, and the RGB line width of the color filter substrate needs to be reduced from 20-30um to 8-12um. Extremely challenging and requires the use of expensive projection exposure machines. [0003] Such as figure 1 As shown, a general color filter substrate includes a black matrix layer 100, a first color-resist layer 210, a second color-resist layer 220, and a third color-resist layer 230 are arranged sequentially on the black matrix layer 100. If this design is maintained, the RGB lines The width is 8-12um, and the process is difficult. [0004] In view of the above problems, the general countermeasures in the prior art are: to adjust the line w...
