Problems solved by technology
like figure 1 as shown, figure 1 It is a schematic diagram of the structure of the mask plate in the prior art. The existing mask plate is usually made of metal light-shielding material, and the mask plate generally includes the exposure area 01 corresponding to the non-display area of the display panel and used for alignment or observation. The test area 02 of the distance between the mask plate and the substrate. The exposure area 01 is generally provided with an exposure pattern 011 that allows ultraviolet light to pass through to form a columnar spacer. Since the test area 02 needs to transmit light, the prior art The part of the mask plate corresponding to the test area is generally a gap. The setting of the gap will cause the exposure pattern to be unable to be set in the test area, that is, the part of the substrate corresponding to the test area will not form a spacer, which will lead to The thickness of the box around the display panel is abnormal, and the display screen is defective

The invention relates to the technical field of displays, and discloses a mask. The mask comprises an exposure area corresponding to a non-display area of a display device and a test area, the test area is used for mask alignment or observation of the distance between the mask and a substrate, exposure patterns are arranged in the exposure area, the test area is covered with an ultraviolet cutoff filter coating allowing visible light to transmit, and exposure patterns are arranged on the ultraviolet cutoff filter coating. Through the mask, box thickness abnormities of the peripheral positions of a display panel can be decreased, and display effect of the display device is improved.
Description
technical field [0001] The invention relates to the technical field of display preparation, in particular to a mask plate. Background technique [0002] The thin film transistor liquid crystal display device is the mainstream of the flat panel display at present. The panel of the thin film transistor liquid crystal display device includes a thin film transistor array substrate and a color filter substrate arranged in parallel, and a liquid crystal layer is arranged between them. In order to control the stable uniformity of the thickness of the liquid crystal layer, a spacer is arranged between the two substrates things. At present, columnar spacers are mostly used in high-performance thin film transistor liquid crystal display devices. When the thin film transistor liquid crystal display device works at high temperature, the liquid crystal molecules will move with the gravitational field, so the phenomenon of gravitational water ripples will appear, which affects the displ...
