Problems solved by technology

[0006] However, in the case of a color filter including quantum dots, the efficiency of the quantum dots, especially blue quantum dots, is poor, and the performance of the color filter is somewhat reduced accordingly. In the case of blue quantum dots, due to the price High, so there is a problem of rising overall manufacturing costs

Synthetic example 1

[0193] Synthesis Example 1: Acrylic resin

[0194] A flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen gas introduction tube was prepared. On the other hand, as a monomer dropping funnel, 74.8 g (0.20 moles) of benzylmaleimide and 43.2 g of acrylic acid were charged (0.30 mol), 118.0 g (0.50 mol) of vinyltoluene, 4 g of tert-butyl peroxy-2-ethylhexanoate, and 40 g of propylene glycol monomethyl ether acetate (PGMEA), and stir and mix them to prepare as chain The transfer agent dripping tank was prepared to add 6 g of n-dodecanethiol and 24 g of PGMEA and then stir and mix them. Thereafter, 395 g of PGMEA was introduced into the flask, and the atmosphere in the flask was replaced with nitrogen from air, and then the temperature of the flask was raised to 90° C. while stirring. Next, the monomer and the chain transfer agent were added dropwise from the dropping funnel. During the dropwise addition, each was carried out for 2 ...

Abstract

The invention provides a blue colored photosensitive resin composition, a color filter, and an image display device. The blue colored photosensitive resin composition of the invention is characterizedby comprising an alkali-soluble resin, a blue colorant, and scattering particles containing a metal oxide having an average particle diameter of 30 to 500 nm, wherein the alkali-soluble resin comprises a Cardo-based binder resin containing at least one repeating unit of a chemical formula 1 and a chemical formula 2. The blue colored photosensitive resin composition of the invention has advantagesof being able to suppress residue generated on a substrate, and excellent in sensitivity, pattern stability, diffusibility, and the like.

Description

technical field [0001] The present invention relates to a blue photosensitive resin composition comprising scattering particles, an alkali-soluble resin and a blue colorant, a color filter and an image display device manufactured using the composition. Background technique [0002] A color filter is a thin-film optical component capable of extracting three colors of red, green, and blue from white light to realize a tiny pixel unit, and the size of one pixel is on the order of tens to hundreds of microns. Such a color filter has a structure in which a black matrix layer is formed in a predetermined pattern on a transparent substrate to shield light at the boundary between pixels, and a pixel portion is sequentially laminated. Each pixel is formed by arranging three primary colors of a plurality of colors (generally, red (R), green (G) and blue (B)) in a predetermined order. [0003] In recent years, a pigment dispersion method using a pigment-dispersed photosensitive resin ...
