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-mentioned problems

manufacture example 1

[0155] Production Example 1. Synthesis of Photoluminescent Green Quantum Dot Particles A-1 of CdSe (Core) / ZnS (Shell) Structure

[0156] CdO (0.4 mmol) and Zinc acetate (4 mmol), Oleic acid (5.5 mL) and 1-Octadecene (20 mL) were placed in the reactor and heated It was made to react at 150 degreeC. Then, in order to remove the acetic acid (acetic acid) produced|generated by the substitution of oleic acid with zinc, the said reactant was left to stand under the vacuum of 100mTorr for 20 minutes. Then, after applying heat at 310°C to obtain a transparent mixture, the mixture 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. After the resulting mixture was grown at 310°C for 5 minutes, the growth was interrupted using an ice bath. Then, it was precipitated with ethanol, the quantu...

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

[0158] A flask equipped with a stirrer, a thermometer, a reflux cooling tube, a dropping funnel, and a nitrogen introduction tube was prepared, and 45 parts by weight of N-benzylmaleimide, 45 parts by weight of methacrylic acid, and tricyclodecyl methacrylate were charged. 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), they were stirred and mixed to prepare a monomer dropping funnel, 6 parts by weight of n-dodecanethiol and 24 parts by weight of PGMEA were charged, stirred and mixed to prepare a chain transfer agent dropping funnel. 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 t...

[0170] (1) Surface illuminance measurement

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

[0172] In general, 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) Determination of development type

[0174] The photosensitive resin compositions of the above examples and comparative examples were coated on a glass substrate by spin coating, then placed on a hot plate and maintained at a temperature of 100° C. for 3 minutes to form a thin film, and then immersed in pH 10.5. The KOH aqueous solution developing s...

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] The color filter is a thin-film optical member that extracts three colors of red, green, and cyan from white light and can exist in fine pixel units, and the size of one pixel is about several tens to several hundreds of micrometers. Such a color filter has a structure in which a black matrix layer is formed in a predetermined pattern on a transparent substrate in order to shield the boundary between each pixel from light, and a plurality of colors (usually, red (R (R)) are used to form each pixel. ), green (G), and blue (B)), pixel portions in which the three primary colors are arranged in a predetermined order are stacked in sequence. In general, color filters can be produced by applying three or more color tones on a transparent substrate by dyeing, electrodeposition, printing, and pigment dispersion. Recently, photosensitive resins using pigment disp...
