Abstract
The present invention provides a VA liquid crystal display panel based on BM-less technology and a manufacturing method thereof. The VA liquid crystal display panel based on BM-less technology includes a color mixture prevention zone (30) that is formed of a stacked arrangement of red color resist (41) and blue color resist (42) 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 (71) and the sub photo spacer (72) and includes a recess (31) formed therein. The main photo spacer (71) is in engagement with a bottom of the recess (31) to increase a height difference between the main photo spacer (71) and the sub photo spacer (72) and thus expanding LC margin and ensuring product yield rate.
