Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a composition, a color filter substrate, a display panel, a display device and a preparation method of the color filter substrate. Background technique [0002] In an existing method for preparing a color filter substrate, a black matrix is ​​first formed on a base substrate, and then a red filter area, a green filter area and a blue filter area are respectively formed on the black matrix. When forming the red filter area, the green filter area and the blue filter area, it needs to be formed through the processes of coating, exposure and development respectively. That is, when the red filter area is formed, the red photoresist is first coated on the black matrix, then the black matrix coated with the red photoresist is exposed, and finally the unexposed area is washed under the action of the developing solution. The red filter area is formed; when the green filter area and ...
