Abstract:
A VA liquid crystal display panel based on BM-less technology and a manufacturing method thereof are provided. The VA liquid crystal display panel based on BM-less technology includes a color mixture prevention zone that is formed of a stacked arrangement of red color resist and blue color resist and is used in combination with a main photo spacer and a sub photo spacer that are formed of a black material as a substitute of a black matrix. Further, the color mixture prevention zone has a portion that corresponds to the main photo spacer and the sub photo spacer and includes a recess formed therein. The main photo spacer is in engagement with a bottom of the recess to increase a height difference between the main photo spacer and the sub photo spacer and thus expanding LC margin and ensuring product yield rate.

Claim (Index 6):
A manufacturing method of a vertical alignment (VA) liquid crystal display panel based on black matrix (BM)-less technology, comprising the following steps:\n (1) providing a lower substrate and forming a thin-film transistor (TFT) layer on the lower substrate; (2) depositing a protective layer on the TFT layer and the lower substrate; (3) forming a color resist layer on the protective layer, wherein the color resist layer comprises red color resist, green color resist, and blue color resist that are arranged in the form of an array and a color mixture prevention zone is arranged between every two adjacent ones of the color resists and is formed of a stacked arrangement of red color resist and blue color resist; the color mixture prevention zone comprises a recess formed therein; (4) depositing and patterning a passivation layer on the color resist layer, forming a pixel electrode layer on the passivation layer, coating enclosure sealant on an edge portion of the lower substrate; (5) providing an upper substrate and forming a common electrode layer on one side of the upper substrate that is adjacent to the lower substrate; (6) using a black material to form a main photo spacer, a sub photo spacer, and an edge frame on a surface of the common electrode layer; and (7) laminating the lower substrate and the upper substrate to each other and filling a liquid crystal layer such that the main photo spacer and the sub photo spacer correspond to the recess with the main photo spacer in engagement with a bottom of the recess and the edge frame and the enclosure sealant engage each other; wherein the main photo spacer has a distal end that is distant from the upper substrate in a predetermined direction away from the upper substrate and in engagement with a bottom of the recess, and the sub photo spacer has a distal end that is distant from the upper substrate in the predetermined direction is spaced from the bottom of the recess, wherein the distal ends of the main photo spacer and the sub photo spacers are spaced from each other in the predetermined direction and a spacing distance between the distal ends of the main photo spacer and the sub photo spacer includes a fraction of a depth of the recess between the bottom of the recess and the surface of the common electrode layer of the upper substrate in the predetermined direction.
