    Abstract: A pigment dispersing agent, a pigment dispersion solution, a color photoresist, and a process for manufacturing the same, and use in the color film substrate and display device. The pigment dispersing agent is an amino-β-cyclodextrin modified polymethacrylate, the amino-β-cyclodextrin modified polymethacrylate being used to disperse a powdered pigment having an aromatic group, wherein the degree of modification by amino-β-cyclodextrin is 5.36%-35.40%. Because β-cyclodextrin moiety is a group having affinity for pigments, it can bind to the aromatic group in the pigment molecular structure, thereby capable of dispersing the powdered pigment having an aromatic group. The pigment dispersion solution prepared from the pigment dispersing agent has small particle size, narrow particle size distribution range, and high storage stability, thereby improving the yield of the display product.

    Abstract translation: 颜料分散剂，颜料分散液，彩色光致抗蚀剂及其制造方法，用于彩色胶片基板和显示装置。 颜料分散剂是氨基-β-环糊精改性的聚甲基丙烯酸酯，用于分散具有芳基的粉末颜料的氨基-β-环糊精改性聚甲基丙烯酸酯，其中氨基-β-环糊精的改性程度为5.36％-35.40 ％。 由于β-环糊精部分是对颜料具有亲和性的基团，因此可以与颜料分子结构中的芳香族基团结合，能够分散具有芳香族基团的粉末状颜料。 由颜料分散剂制备的颜料分散溶液具有粒径小，粒度分布范围窄，储存稳定性高，从而提高显示产品的产率。

    Abstract: Embodiments of the present invention provide a preparation method of a patterned film, a display substrate and a display device, avoiding falling off of a film layer occurring in the process of peeling off a photoresist layer. The preparation method of the patterned film comprises: forming a preset film layer on a surface of a preset substrate; covering the preset film layer with an isolation layer; forming a photoresist layer on a surface of the isolation layer and forming a pattern of the isolation layer with a patterning process; then removing the preset film layer which is not covered by the pattern of the isolation layer, peeling off the photoresist layer and removing the remaining, isolation layer to form a pattern of the preset film layer.
