Abstract

The invention relates to a blue photoresistance composition and a colorful optical filter. The blue photoresistance composition comprises the following components in parts by weight: 100 parts of alkali soluble resin, 100 parts of optical active compound, 10 parts of photoinitiator, 200 parts of organic solvent and 50 parts of blue pigment dispersion, wherein the optical active compound contains aliphatic acrylate oligomers with the number of functional groups being more than 4, and/or aliphatic acrylate monomers and compounds containing olefin double bond. The blue pattern photoresistance layer of the colorful optical filter contains the blue photoresistance composition. By the invention, the xanthochromia of the optical active compound can be reduced, color difference of the blue photoresistance layer is reduced, flatness and no residue of the surface of a membrane layer are ensured, and the production requirement is finally met.

Description

technical field [0001] The invention relates to a preparation technology of a color filter for a flat panel display, in particular to a blue photoresist composition and a color filter. Background technique [0002] With the rapid popularization of flat panel display products such as Liquid Crystal Display (LCD for short) and Organic Light Emitting Diode display (OLED for short), the requirements for color display of the display are constantly increasing. Color filters are the key raw materials for flat panel display products such as LCD panels and OLEDs to achieve color display. [0003] The color filter is a color filter film composed of three colors of red, green and blue. The photoresist composition of the three colors is regularly made on a glass substrate. Using the principle of light filtering, red, green and blue are produced. Three colors, three colors mixed according to different intensities to produce a variety of colors. [0004] There are many methods for prepa...
