Abstract:
A fabricating method of photo spacers in liquid crystal display (LCD) panel and a LCD panel are provided, including the following steps: forming a first pad and a second pad on an array substrate; forming a black spacer layer on the array substrate, and covering the first and the second pads by the black spacer layer; and patterning the black spacer layer to obtain a main photo spacer, an sub photo spacer, and a black matrix having a height difference, the main photo spacer being located above the first pad, and the sub photo spacer being located above the second pad, and the main photo spacer being higher than the sub photo spacer. The disclosure can reduce the material sensitivity requirement for fabricating the black spacer layer, reduce the alignment difficulty of the multilayer color resist pad, thereby reducing the fabrication cost of the photo spacers and the LCD panel.

Claim (Index 2):
The fabricating method of a photo spacer in a liquid crystal display panel according to  claim 1 , wherein the step of forming a first pad and a second pad on the array substrate comprises the following steps:\n forming a color resist layer on the array substrate; exposing and developing the color resist layer by using a conventional mask to obtain the first pad and the second pad when the color resist layer comprises color resist regions with different heights, and the height difference between the color resist regions with different heights meets a setting value of height difference; exposing and developing the color resist layer by using one of a grayscale mask, a semi-transparent mask, and a slit mask, and a conventional mask to obtain the first pad and the second pad when the heights of different color resist regions on the color resist layer are the same or the color resist layer comprises color resist regions with different heights, and the heights difference between the color resist regions with different heights do not meet the setting value of the color resist regions with different heights.
