Problems solved by technology

[0005] The present application relates to a color filter substrate and a manufacturing method thereof, which are used to solve the problem in the prior art that the heights of the spacers in the display area and the non-display area of ​​the liquid crystal display panel are different, which causes the film thickness of the liquid crystal panel to be different. Causes the problem of uneven display in the display area of ​​the LCD panel

Abstract

The invention relates to a color film substrate and a manufacturing method thereof. A first spacer is disposed in a display area; and a second spacer is disposed in a non-display area. A virtual colorresistance layer is arranged in the non-display area and has the same color as a third color resistance layer; and the height of the first spacer is larger than or equal to that of the second spacer.The color film substrate has the following beneficial effects: because the virtual color resistance layer is arranged in the non-display area and the space of one part of non-display area is occupied, the height of the second spacer in the non-display area is equal to the height of the first spacer in the display area while the total amounts of the spacer solutions are same, so that the film thickness consistence of the display area and the non-display area is ensured and the occurrence of display unevenness is reduced; the virtual color resistance layer and the last color resistance layer inthe display area are made together and the virtual color resistance layer is slightly lower than the color resistance layer in the display area in a reasonable range, so that the operability of the non-display area is enhanced; and the process is simple.

Description

technical field [0001] The present application relates to the display field, in particular to a color filter substrate, a manufacturing method thereof, and a liquid crystal display device. Background technique [0002] With the rapid development of liquid crystal display technology (LCD, Liquid Crystal Display), major manufacturers have higher and higher requirements for panel image quality. The production of high-quality, Mura-free panels has become the ultimate pursuit of every panel factory. Due to differences in panel peripheral design, etc., display unevenness occurs around the display panel, that is, peripheral mura occurs. Among them, one of the most common reasons for peripheral Mura is that the film thickness of the non-display area around the display panel is inconsistent with the film thickness of the display area, resulting in the difference in box thickness. [0003] see attached figure 1 , is a schematic structural diagram 100 of a common display panel in th...
