Abstract

The invention discloses a mask for a display panel manufacturing process. The mask comprises a filter layer, a first light shield layer and a carrier, the filter layer comprises at least three filter portions in one-to-one correspondence to color photo-resists, so that light with different wavelengths can pass the filter portions, only the light with the wavelength in color as same as that of the corresponding color photo-resist can pass each filter portion, the first light shield layer comprises a plurality of light shield blocks arranged at intervals, two ends of each filter portion are respectively provided with one light shield block, the carrier can transmit light, and the filter layer and the first light shield layer are arranged on the carrier. The mask can be shared in the display panel manufacturing process, mask materials and individuals are saved, replacement of different masks is omitted, and manufacturing process switching time is greatly shortened.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, relates to a photomask applied in the manufacturing process of a display panel. Background technique [0002] Liquid crystal displays have many advantages such as thin body, power saving, and no radiation, and have been widely used. Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal panel and a backlight module. The working principle of the liquid crystal panel is to place liquid crystal molecules between two parallel glass substrates, and apply a driving voltage on the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light from the backlight module to produce a picture. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occupied a dominant position in the display field due to its low power...
