Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a negative coloring photosensitive resin composition, an optical filter, and a liquid crystal display device. Background technique [0002] In the display field, in order to form various photocurable patterns such as optical filters, it is necessary to use a negative coloring photosensitive resin composition. In the past, a negative-colored photosensitive resin composition including red, green, and blue was uniformly coated on a black matrix patterned substrate, then heated and dried, and the uniformly coated film was exposed and developed to prepare a filter , and further high-temperature heating and post-baking are required to form pixels of each color, and the above process is repeated for each color. [0003] In order to make the optical filter have better adhesion and chemical resistance, in the past, it was necessary to carry out a post-baking pr...
