Patent ID: 10048553

Abstract:
The present invention provides a BOA liquid crystal display panel and a manufacturing method thereof. The BOA liquid crystal display panel is structured to have a TFT (T) entirely located on a first black matrix (12) and further, a second black matrix (17) is arranged between the TFT (T) and the passivation protection layer (18) such that the second black matrix (17) and the first black matrix (12) completely enclose the TFT (T) to block light emitting from a backlight module located under an array substrate (1) in a direction toward an active layer (14) and also to block reflecting light irradiating the active layer (14) from lateral sides and a top side to better prevent light irradiating the active layer of the TFT for preventing photo leakage current, ensuring stable performance of the TFT device, and improving image displaying quality. The manufacturing method of the BOA liquid crystal display panel of the present invention can overcome the issue of photo leakage current induced by backlighting irradiating the active layer of the TFT  the active layer and also helps reduce the number of masks used, shorten the manufacturing time, and increase the manufacturing efficiency.
