Problems solved by technology

[0004] However, the color reproduction is presented by the light irradiated by the light source passing through the color filter. Since a part of the light is absorbed by the color filter in the process, the light efficiency is reduced. Moreover, due to the characteristics of the pigment used as the color filter, there is a perfect The color reproduction is impossible to the fundamental limit of
[0005] Korean Laid-Open Patent No. 2012-112188 discloses a red coloring composition for color filters and a color filter, but does not propose a solution to the above problems

manufacture example 1

[0155] Production example 1. Synthesis of photoluminescent green quantum dot particle A-1 with CdSe (core) / ZnS (shell) structure

[0156] CdO (0.4mmol) and zinc acetate (Zincacetate) (4mmol), oleic acid (Oleicacid) (5.5mL) and 1-octadecene (1-Octadecene) (20mL) were put into the reactor together, heated to 150 ℃ to make it react. Then, in order to remove acetic acid produced by substituting oleic acid with zinc, the reactant was left to stand under a vacuum of 100 mTorr for 20 minutes. Then, heat at 310° C. was applied to obtain a transparent mixture, which was maintained at 310° C. for 20 minutes, and then 0.4 mmol of Se powder and 2.3 mmol of S powder were dissolved in 3 mL of trioctylphosphine. The Se and S solutions were rapidly injected into the reactor containing the Cd(OA)2 and Zn(OA)2 solutions. The resulting mixture was grown at 310° C. for 5 minutes, and then the growth was stopped in an ice bath. Then, it was precipitated with ethanol, and the quantum dots were...

manufacture example 2

[0157] Production Example 2. Synthesis of Alkali-Soluble Resin

[0158] Prepare a flask equipped with a stirrer, a thermometer, a reflux cooling tube, a dropping funnel, and a nitrogen introduction tube, and put in 45 parts by weight of N-benzylmaleimide, 45 parts by weight of methacrylic acid, and tricyclodecanyl methacrylate. After 10 parts by weight, 4 parts by weight of tert-butyl peroxy-2-ethylhexanoate, and 40 parts by weight of propylene glycol monomethyl ether acetate (hereinafter referred to as PGMEA), stir and mix, prepare a monomer dropping funnel, 6 parts by weight of n-dodecanemercaptan and 24 parts by weight of PGMEA were charged, stirred and mixed, and a chain transfer agent dropping funnel was prepared. Then, 395 parts by weight of PGMEA was introduced into the flask, and the atmosphere in the flask was changed from air to nitrogen, and then the temperature of the flask was raised to 90° C. while stirring. Then, the dropping of the monomer and the chain tran...

experiment example

[0170] (1) Surface illuminance measurement

[0171] Using the photosensitive resin compositions of the above Examples and Comparative Examples, the self-luminous color pattern substrate obtained by the same method as in the color filter production example was measured on the surface of the pixel using a surface illuminance measuring machine DEKTAK-6M (manufactured by Veeco). surface illuminance. The measured surface illuminance is described in Table 2 below.

[0172] Generally, if the surface illuminance of the color filter pixel surface is 100 nm or more, it cannot be used due to surface bleeding.

[0173] (2) Development type determination

[0174] After coating the photosensitive resin composition of the above-mentioned examples and comparative examples on the glass substrate by the spin coating method, place it on a heating plate and maintain it at a temperature of 100° C. for 3 minutes. The KOH aqueous developing solution was confirmed to be a dissolved form or a p...

Abstract

The invention relates to a photosensitive resin composition which realizes greatly improved manufacturing brightness and color reproducibility through particles including luminescent quantum dots, a photopolymerizable composition including carboxyl, a photopolymerizable evocator, alkali soluble resin, and a solvent.

Description

technical field [0001] The present invention relates to a photosensitive resin composition. Background technique [0002] A color filter is a thin-film optical component that extracts three colors of red, green, and cyan from white light and exists in fine pixel units, and the size of one pixel is about tens to hundreds of microns. Such a color filter adopts a structure in which a black matrix layer is formed in a predetermined pattern on a transparent substrate in order to shield the boundary portion between individual pixels, and a plurality of colors (generally, red (R ), green (G) and blue (B)) pixel units arranged in a determined order in three primary colors are sequentially stacked. In general, color filters can be manufactured by coating three or more color tones on a transparent substrate by dyeing, electrodeposition, printing, or pigment dispersion. Recently, pigment dispersion-type photosensitive resins are mainly used. pigment dispersion method. [0003] The p...
