Abstract
A method for manufacturing a BOA liquid crystal display panel is provided. The BOA liquid crystal display panel is structured to have a TFT entirely located on a first black matrix and further, a second black matrix is arranged between the TFT and the passivation protection layer such that the second black matrix and the first black matrix completely enclose the TFT to block light emitting from a backlight module located under an array substrate in a direction toward an active layer and also to block reflecting light irradiating the active layer 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 method helps overcome the issue of photo leakage current induced by backlighting irradiating the active layer of the TFT.
