manufacture example 1

[0092] Production example 1. Synthesis of photoluminescent green quantum dot particle A with CdSe (core) / ZnS (shell) structure

[0093]CdO (0.4mmol), zinc acetate (4mmol), oleic acid (Oleic acid) (5.5mL) and 1-octadecene (1-Octadecene) (20mL) were added into the reactor together, heated It was made to react at 150 degreeC. Then, in order to remove acetic acid generated by substituting zinc for oleic acid, the reactant was left to stand under a vacuum of 100 mTorr for 20 minutes. Then, after applying heat at 310° C. to obtain a transparent mixture, which was maintained at 310° C. for 20 minutes, 0.4 mmol of Se powder and 2.3 mmol of S powder were dissolved in 3 mL of trioctylphosphine. The resulting Se and S solutions were quickly injected into the Cd(OA) 2 and Zn(OA) 2 solution in the reactor. After the mixture thus obtained was grown at 310° C. for 5 minutes, the growth was interrupted using an ice bath. Then, the quantum dots were precipitated with ethanol and separate...

Abstract

The invention relates to a self emission type photosensitive resin composition, a color filter manufactured using thereof and an image display device having the same. Particularly, the invention relates to the self emission type photosensitive resin composition which comprises an alkali-soluble resin, photoluminescence quantum point particles, a photo-polymerizable compound, a photo-polymerization initiator and a solvent. The alkali-soluble resin comprises polymerizable unsaturated bonds in the structure, and the equivalent of acryloyl is 300-2000g / eq. According to the self emission type photosensitive resin composition, problems of light efficiency reduction and photosensing characteristic reduction in hard baking process are prevented; and the high-quality color filter with excellent brightness characteristic can be realized.

Description

technical field [0001] The present invention relates to a self-luminous photosensitive resin composition, a color filter manufactured using the same, and an image display device. Background technique [0002] A color filter is a thin-film optical component that can extract three colors of red, green, and blue from white light to form a fine pixel unit, and the size of one pixel is about tens to hundreds of microns. Such a color filter includes: a black matrix layer formed in a predetermined pattern on a transparent substrate in order to shield the boundary between individual pixels; and a plurality of colors (usually red (R), green ( G) and blue (B) 3 primary colors) The structure in which the pixel parts arranged in a predetermined order are sequentially stacked. In general, color filters can be manufactured by coating three or more hues on a transparent substrate by dyeing, electrodeposition, printing, pigment dispersion, etc. Recently, pigment dispersion using a pigment-...
