Abstract

The embodiment of the invention provides a filter film, a preparation method of the filter film, a display panel and a display device. The filter film comprises a substrate; a pretreatment layer arranged on the substrate, wherein the material of the pretreatment layer comprises a target material; a black matrix layer arranged on the side, away from the substrate, of the pretreatment layer, wherein the black matrix layer comprises a plurality of limiting openings distributed in an array mode, at least parts of the pretreatment layer being exposed out of the limiting openings; and a color resistance layer which comprises more than two color resistances with different colors, wherein the color resistances are respectively positioned in the limiting openings, and the material of at least one color resistance comprises a reaction material capable of generating chemical bonding reaction with the target material. The problem that a large amount of color resistance materials are wasted can be solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a filter film, a preparation method of the filter film, a display panel and a display device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as light and thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, computer screen and notebook screen, etc. [0003] Generally, an LCD display device needs to use a filter film to realize color display. The filter film includes a black matrix (BlackMatrix, BM) and a color resist arranged on the BM layer. In the traditional method of preparing a filter film, the color resist is usually patterned after the entire layer of the color resist is placed on the BM. This method causes a large amount of color resist material to be developed and wasted. Contents of the invention [0004] Embodiments of the present application pr...
