Liquid crystal display (LCD) panel and manufacturing method of color filter substrate thereof

Abstract

The invention provides a liquid crystal display (LCD) panel. The LCD panel comprises an active component array substrate, a color filter substrate, an LC layer and a plurality of optical spacers, wherein the active component array substrate comprises a first substrate and a plurality of film layers formed on the first substrate, and the film layers are stacked on the first substrate so as to form a plurality of convex supporting parts; the color filter substrate is opposite to the active component array substrate and comprises a second substrate as well as a black matrix layer, a color photoresistive layer and a transparent electrode layer which are formed on the second substrate, and the black matrix layer is provided with a plurality of sunken parts corresponding to the supporting parts; the plurality of the optical spacers are separately configured between each corresponding supporting part and sunken part; and the LC layer is configured between the active component array substrate and the color filter substrate. The invention further provides a manufacturing method of a color filter substrate.

Description

Technical field [0001] The invention relates to a display panel, and in particular to a manufacturing method of a liquid crystal display panel and a color filter substrate thereof. Background technique [0002] Liquid crystal displays are widely used in modern information equipment, and generally include a liquid crystal display panel, a backlight module that provides flat light for the liquid crystal display panel, and a driving circuit that controls the display of the liquid crystal display panel. A liquid crystal display panel usually includes two substrates facing up and down, and an optical spacer can be arranged between the two substrates to maintain the distance between the two substrates, so that the thickness of the liquid crystal display panel is uniform. [0003] figure 1 It is a partial cross-sectional schematic diagram of a liquid crystal display panel in the prior art. Please refer to figure 1 , the liquid crystal display panel comprises a color filter subst...

AI Technical Summary

Problems solved by technology

Since the material of the optical spacer 20 can transmit light, and the end of the optical spacer 20 close to the color filter substrate 18B is not covered by the black matrix layer 15, the connection between the substrate 11 and the optical spacer 20 and its surroundings are prone to light leakage. The display performance of the LCD panel is adversely affected
