Abstract: The present invention provides a LTPS display panel and a manufacture method thereof. In the LTPS display panel, the edge of the back matrix (12) comprises a convex part (104) capable of ensuring that the light emitted from the pixel unit (22) of the array substrate (20) only penetrates through the color resist block (131/132/133) corresponding to the pixel unit (22) in the color film substrate (10), and no light leakage happens between adjacent pixel units and thus, can reduce the large view angle color washout to improve the display quality of the LTPS display panel. In the manufacture method of the LTPS display panel, one halftone mask process is employed to form the black matrix (12), and the edge of the back matrix (12) comprises a convex part (104) which can better shade the light leakage between adjacent pixel units as watching in the large view angle.
