Embodiment Construction

[0074] Please refer to figure 1 , which shows a flow chart of steps for making photosensitive spacers according to an embodiment of the present invention, and referring to figure 2 , is a schematic diagram of the steps of manufacturing a black matrix substrate according to an embodiment of the present invention.

[0075] First, as in step 110 and figure 2 As shown, a photosensitive black light-shielding material is coated on a transparent substrate 210 to obtain a black photoresist layer 220 with uniform thickness. According to an embodiment of the present invention, the photosensitive black light-shielding material can be evenly coated on the transparent substrate 210 by a suitable method, such as a spin coating method. The transparent substrate 210 can be a glass substrate, and the photosensitive black light-shielding material can be an alkali-soluble black photoresist material, which is a negative photoresist material, and the light-shielding material in the photoresist...

Abstract

The invention discloses a method for preparing sensitizing interstice. The method comprises black matrix'' cardinal plate with a plurality of interstices and colourful layer open pores is formed on the transparent carrier, colorful filter layer is formed on the black matrix'' cardinal plate, and then transparent conducting layer is formed on the black matrix'' cardinal plate and the colorful filter layer in photolithograpic technology. Then sensitizing spacing material is coated on the transparent conducting layer, back exposal cross linkage working procedure using black matrix'' as mask directly is processed, ultraviolet ray is irradiated from lower of the transparent carrier, graph is defined permeation black matrix'' interstice open to cross link sensitizing spacing material, at last the interstice layer is formed through the steps of developing and roasting.

Description

technical field [0001] The invention relates to a method for making a photosensitive spacer of a flat panel display, and in particular to a method for making an ultra-high resolution photosensitive spacer. Background technique [0002] A color filter is a key component of colorization of a liquid crystal display. Through the processing of the color filter, the strong light emitted by the LCD backlight module can be displayed in a colorful picture. The production of the color filter is to make a black matrix on the glass substrate to form intervals, and then arrange the three primary colors of red, green and blue in each pixel of the colorization layer in sequence. The black matrix and the colored layer are made by using photosensitive material with yellow light lithography process. [0003] The main function of the spacer is to maintain the distance between the upper and lower glass substrates of the liquid crystal display, forming a space to fill the liquid crystal. The c...
