Abstract

The invention discloses a color film substrate for a display, a method for manufacturing the color film substrate and a light mask thereof. The color film substrate comprises a substrate body and a plurality of color resistance patterns. The color resistance patterns are arranged on the substrate body, the adjacent color resistance patterns are partially overlapped on one another, and the thicknesses of the lower color resistance patterns in overlapped regions are gradually reduced in the directions of the edges of the lower color resistance patterns. Owing to the mode, the color film substrate, the method and the light mask have the advantages that horn segment difference of the overlapped regions of the adjacent RGB (red, green and blue) color resistance patterns of the color film substrate can be reduced, and accordingly the liquid crystal efficiency can be improved; extra OC (over-coat) flat layers on RGB color resistance layers of the color film substrate can be omitted, accordingly, the production cost of liquid crystal display panels can be reduced, and the production efficiency can be improved.

Description

technical field

[0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate for a display, a manufacturing method thereof, and a photomask of the color filter substrate. Background technique

[0002] The TFT-LCD liquid crystal panel includes an array substrate, a color filter substrate, and a liquid crystal layer sandwiched between the array substrate and the color filter substrate. It uses a circuit to generate an electric field to drive the liquid crystal molecules, and produces different optical effects through the physical characteristics of the liquid crystal. The change of the three primary colors of RGB on the film substrate realizes full-color display images.

[0003] The color filter substrate is a necessary material for the colorization of TFT-LCD panels. It usually includes a pixel filter film and a black matrix layer. The pixel filter film includes red, green and blue pixel filters arranged in a predete...
