Problems solved by technology

[0003] Recently, as one of the methods for realizing color filters, a pigment dispersion method using a pigment dispersion type photosensitive resin has been applied, but the following problems have arisen: When the light irradiated by the light source passes through the color filter, part of the light is absorbed by the color filter to reduce the light efficiency. In addition, depending on the characteristics of the pigment contained in the color filter, the color reproduction is reduced.
[0006] However, in the case of a color filter including quantum dots, as the efficiency of the quantum dots, especially the efficiency of the cyan quantum dots, deteriorates, the The performance may be slightly lowered, and in the case of cyan quantum dots, there is a problem that the overall manufacturing cost increases due to the high price

Synthetic example 1

[0233] Synthesis Example 1: Alkali Soluble Resin

[0234] A flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen 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), vinyl toluene 118.0g (0.50 mol), peroxy-2-ethylhexanoic acid tert-butyl ester 4g, propylene glycol monomethyl ether acetate (PGMEA) 40g, stir and mix and prepare as chain transfer The dropping tank of the agent was prepared by putting 6 g of n-dodecanethiol and 24 g of PGMEA, stirring and mixing. Then, 395 g 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. Next, drop the monomer and chain transfer agent from the dropping funnel. Dropping is carried out for 2 hours while maintaining 90°C, and after 1 hour, the temperat...

[0235] Synthesis Example 2: Synthesis of Compounds of Chemical Formula 1

[0236] In a three-necked round flask of 3000ml, 3', 6'-dihydroxyspiro (fluorene-9,9-xantene) (3', 6''-dihydroxyspiro(fluorene-9,9-xantene) 364.4 of chemical formula 3 g and 0.4159g of tert-butylammonium bromide are mixed, and 2359g of epichlorohydrin is charged, and heated to 90°C to make it react. Analyzed by liquid chromatography, if 3,6-dihydroxy spiro (fluorene-9,9-xanthene ) disappears completely, then cool to 30 ℃, add 50% NaOH aqueous solution (3 equivalents) slowly.Use liquid chromatography analysis, if epichlorohydrin disappears completely, then after extracting with dichloromethane, after washing 3 times with water, will After the organic layer was dried over magnesium sulfate, dichloromethane was distilled off under reduced pressure, and recrystallization was performed using a mixing ratio of dichloromethane and methanol of 50:50.

[0237] After mixing 1 equivalent of epoxy compound thus s...

Abstract

A photosensitive resin composition according to the present invention comprises: an alkali soluble resin; and scattering particles having an average particle diameter of 30-500nm and comprising metaloxide. The alkali soluble resin comprises one or more selected from a group consisting of a first cardo-based binder resin which comprises a compound represented by chemical formula (1) and is polymerized and a second cardo-based binder resin which comprises a compound represented by chemical formula (2) and is polymerized. The photosensitive resin composition according to the present invention can provide excellent color reproduction properties and high luminous efficiency and can produce a high-quality image.

Description

technical field [0001] The present invention relates to a photosensitive resin composition containing specific scattering particles and an alkali-soluble resin, a color filter and an image display device manufactured using the photosensitive resin composition. Background technique [0002] A color filter is a thin-film optical component that extracts the three colors of red, green, and cyan from white light and operates in fine pixel units. The size of one pixel is about tens to hundreds of microns. In order to shield the boundary portion between individual pixels, such a color filter has a structure in which a black matrix layer is formed in a predetermined pattern on a transparent substrate and a plurality of colors (usually red (R ), green (G), and cyan (B)) in which three primary colors are arranged in a specified order, the pixel portions are sequentially stacked. [0003] Recently, as one of methods for realizing a color filter, a pigment dispersion method using a pig...
