Color filter substrate, manufacturing method thereof, and liquid crystal display panel

Abstract

The invention discloses a color filter substrate, its manufacturing method and a liquid crystal display panel, relates to the field of liquid crystal displays, and is invented for improving the display uniformity of the liquid crystal display panel. The liquid crystal display panel includes a color filter substrate and an array substrate arranged in a box opposite to the color filter substrate, liquid crystals are drip-filled between the color filter substrate and the array substrate, and the color filter substrate is spaced apart from There are a main column spacer and an auxiliary column spacer, the height of the main column spacer is greater than the auxiliary column spacer, and the main column spacer and the auxiliary column spacer The bottom of the spacer is connected. The manufacturing method of the color filter substrate includes: providing a glass substrate; forming a main columnar spacer and an auxiliary columnar spacer connected at the bottom while forming a black matrix on the glass substrate. The invention can be used to make liquid crystal displays.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a color filter substrate in a liquid crystal display, a manufacturing method thereof, and a liquid crystal display panel. Background technique [0002] With the rapid development of science and technology, liquid crystal display (TFT LCD) is gradually replacing the traditional cathode ray tube (CRT) due to its low power consumption and no radiation, and has become the mainstream of flat-panel displays. [0003] Such as figure 1 As shown, the color filter substrate 1 in the prior art is provided with a black matrix 11 on the color filter substrate 1, and a color pixel unit 12 is arranged in the black matrix 11, and each color pixel unit 12 is composed of red (Red, R ), blue (Blue, B), and green (Green, G) three sub-pixels. At the position corresponding to the black matrix 11, there are generally columnar spacers evenly and regularly distributed at a density of 1 / 24-1 / 6 (ev...

Problems solved by technology

[0005] The inventors have found that when the liquid crystal display panel is subjected to external pressure, on the one hand, the panel sags due to insufficient restoring force of the columnar spacer, which changes the propagation path of the light from the backlight source and affects the gray scale of the display. On the other hand, when an external force is applied to the liquid crystal display panel, a parallel dislocation will occur between the color filter substrate and the array substrate, thus making the columnar spacers on the color filter substrate displacement between the array substrate and the

When the external force is removed, due to the friction between the columnar spacer and the array substrate, the above-mentioned parallel dislocation is difficult to recover naturally, which will cause horizontal dislocation light leakage, which further makes the display unevenness of the liquid crystal display panel.
