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 10):
A vertical alignment (VA) liquid crystal display panel based on black matrix (BM)-less technology, comprising: a lower substrate, a thin-film transistor (TFT) layer formed on the lower substrate, a protective layer formed on the TFT layer, a color resist layer formed on the protective layer, a passivation layer formed on the color resist layer, a pixel electrode layer formed on the passivation layer, an upper substrate arranged opposite to the lower substrate, a common electrode layer formed on one side of the upper substrate that is adjacent to the lower substrate, a main photo spacer and a sub photo spacer formed on the common electrode layer, an enclosure sealant formed on an edge portion of the lower substrate, an edge frame formed on an edge portion of the common electrode layer and corresponding to the enclosure sealant, and a liquid crystal layer arranged between the lower substrate and the upper substrate;\n the color resist layer comprising red color resist, green color resist, and blue color resist that are arranged in the form of an array, a color mixture prevention zone being arranged between every two adjacent ones of the color resists and formed of a stacked arrangement of red color resist and blue color resist; the main photo spacer and the sub photo spacer being arranged to correspond to the color mixture prevention zone, the color mixture prevention zone having a portion that is opposite to the main photo spacer and the sub photo spacer and is provided with a recess formed therein in such a way that a distal end of the main photo spacer that is distant from the upper substrate in a predetermined direction away from the upper substrate is in engagement with a bottom of the recess, and a distal end of the sub photo spacer 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; the main photo spacer, the sub photo spacer, and the edge frame each formed of a material that comprises a black material; wherein in the color mixture prevention zone, the blue color resist is stacked on the red color resist and the recess is formed in the blue color resist, the red color resist having a flat upper surface; wherein the TFT layer comprises: a gate electrode formed on the lower substrate, a gate insulation layer formed on the lower substrate and the gate electrode, a semiconductor layer formed on the gate insulation layer, and a source electrode and a drain electrode formed on the gate insulation layer and respectively connected to two opposite ends of the semiconductor layer; the pixel electrode layer being connected through a via extending through the passivation layer, the color mixture prevention zone, and the protective layer to connect to the drain electrode; wherein the color resist layer further comprises at least one of white color resist and yellow color resist.
