Abstract

The invention provides an LTPS (low temperature poly silicon) display panel and a manufacturing method thereof. According to the LTPS display panel, bulge parts (104) are arranged on the edge of a black matrix (12), light rays emitted from pixel units (22) of an array substrate (20) can penetrate out only from color stop blocks (131,132 and 133) corresponding to the pixel units (22) in a color film substrate (10), light leakage of the adjacent pixel units can be prevented, so that large-viewing-angle color offset is reduced, and the display quality of the LTPS display panel is improved. According to the manufacturing method of the LTPS display panel, the black matrix (12) is formed through a halftone photomask manufacture procedure, the bulge parts (104) are arranged on the edge of the black matrix (12), light leakage of the adjacent pixel units can be better blocked during large-angle viewing, so that the large-viewing-angle color offset is reduced, and the display quality of the LTPS display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an LTPS display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, TVs, personal digital assistants due to their advantages of high image quality, power saving, thin body and wide application range. , digital cameras, notebook computers, desktop computers and other consumer electronics products have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include an LTPS display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires bet...
