example 1
[0052] like Figure 7 As shown, it is a schematic structural diagram of manufacturing a color filter substrate in the AD-SDS display mode, and the steps of manufacturing the color filter substrate include:
[0053] S51, providing a glass substrate 1;
[0054] S52, depositing a layer of indium tin oxide metal thin film on the lower surface of the glass substrate by magnetron sputtering to form an indium tin oxide metal common electrode layer 7;
[0055] S53, coating a layer of black matrix resin material film on the upper surface of the glass substrate 1 on which the indium tin oxide metal common electrode layer 7 is formed, and using a mask to perform exposure and development processing to obtain fully exposed areas and unexposed areas, said The unexposed area corresponds to the black matrix pattern, the fully exposed area corresponds to other areas that do not need the black matrix pattern, and the fully exposed area is etched to form a black matrix layer 2 on the glass subs...
example 2
[0063] This example is also the manufacturing method of the color filter substrate in the AD-SDS display mode, the manufacturing method of the color filter substrate is the same as the method in Example 1, and the specific steps are also as follows Figure 7 shown.
[0064] The difference between this example and Example 1 is that the alignment film of the color filter substrate in this example is made of a photosensitive resin that has both protection and alignment functions, such as acrylic resin. Since the alignment film has protection and orientation functions at the same time, the alignment film itself can form a relatively flat film. When the alignment liquid is applied, the alignment liquid will not be locally too thick or too thin, so that the liquid crystal can be aligned unanimous.
example 3
[0066] like Figure 8 As shown, it is a schematic structural diagram of manufacturing a color filter substrate in the TN display mode, and the steps of manufacturing the color filter substrate include:
[0067] S61, providing a glass substrate 1;
[0068] S62, coating a black matrix resin material film on the surface of the glass substrate 1, using a mask to perform exposure and development processing to obtain a fully exposed area and an unexposed area, the unexposed area corresponds to the black matrix pattern, and the fully exposed area corresponds to the non-exposed area. In other areas where black matrix patterns are required, black matrix layer 2 is formed by etching the fully exposed area;
[0069] S63, coating a red sub-pixel resin material film on the surface of the glass substrate 1 on which the black matrix layer 2 is formed, and performing exposure and development using a mask to obtain a fully exposed area and an unexposed area, and the unexposed area corresponds...
