Problems solved by technology

[0018] In the case of a general photosensitive resin composition, in order to polymerize, it is necessary to use a photoinitiator, but not only the fluorescence efficiency of the phosphor is reduced due to the free radicals generated by the photoinitiator, but also the photoresisting process in the photolithography process is caused. New problems such as yellowing of the color conversion layer due to photoinitiators in the post-baking process

Synthetic example 1

[0185] Synthesis example 1. Binder resin B1

[0186] 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 mol) of benzylmaleimide and 43.2 g of acrylic acid ( 0.30 mol), vinyltoluene 118.0g (0.50 mol), tert-butyl peroxy-2-ethylhexanoate 4g, propylene glycol monomethyl ether acetate (PGMEA) 40g, stir and mix and prepare as chain transfer In the agent dropping tank, 6 g of n-dodecyl mercaptan and 24 g of PGMEA were put in and stirred and mixed to prepare.

[0187] Then, 395 g of PGMEA was introduced into the flask, and after changing the atmosphere in the flask from air to nitrogen, the temperature of the flask was raised to 90° C. while stirring. Then, the monomer and the chain transfer agent were added dropwise from the dropping funnel. The dropwise addition was carried out for 2 hours while maintaining 90°C. After 1 hour, the tempera...

[0188] Synthesis example 2. Binder resin B2

[0189] Introduce 182g of propylene glycol monomethyl ether acetate into a flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen introduction pipe. After changing the atmosphere in the flask from air to nitrogen, the temperature is raised to 100°C. The dropping funnel was added dropwise to the flask in 2 hours containing 70.5 g (0.40 moles) of benzyl methacrylate, 45.0 g (0.50 moles) of methacrylic acid, and 44.5 g (44.5 g) of monomethacrylate ( 0.10 mol), and a solution in which 3.6 g of azobisisobutyronitrile was added to a mixture of 136 g of propylene glycol monomethyl ether acetate, and stirring was further continued at 100° C. for 5 hours.

[0190] Next, the atmosphere in the flask was changed from nitrogen to air, and 30 g [0.2 mol, (40 mol % relative to the carboxyl group of methacrylic acid used in this reaction)] of glycidyl methacrylate, tris(dimethyl 0.9 g of aminomethyl)p...

Synthetic example 3

[0191] Synthesis example 3. Binder resin B3

[0192] Introduce 182 g of propylene glycol monomethyl ether acetate into a flask equipped with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen introduction pipe, and after changing the atmosphere in the flask from air to nitrogen, heat up to 100° C. The liquid funnel was added dropwise to the flask containing 70.5 g (0.40 moles) of benzyl methacrylate, 45.0 g (0.50 moles) of methacrylic acid, and 22.0 g of 2-(2-methyl) adamantyl methacrylate. g (0.10 mol) and a mixture of 136 g of propylene glycol monomethyl ether acetate and 3.6 g of azobisisobutyronitrile were dissolved, and stirring was further continued at 100° C. for 5 hours.

[0193] Next, the atmosphere in the flask was changed from nitrogen to air, and 30 g [0.2 mol, (40 mol % relative to the carboxyl group of methacrylic acid used in this reaction)] of glycidyl methacrylate, tris(dimethyl 0.9 g of aminomethyl)phenol and 0.145 g of hydroqu...

Abstract

The invention provides a self emission type photosensitive resin composition and a display device comprising a color conversion layer prepared thereby, and more concretely relates to a self emission type photosensitive resin composition comprising fluorochrome, a light polymerism compound, an oxime ether photopolymerization initiator, binder resin and a solvent, and a display device comprising a color conversion layer prepared thereby. The color conversion layer can eliminate the low lighting efficiency caused by existing color filter and light initiator, solve the problem caused by xanthochromia, and keep a high brightness and excellent color conversion features and high lighting efficiency when being arranged in the display device, thus realizing high quality and clear images.

Description

technical field [0001] The present invention relates to a self-luminous photosensitive resin composition capable of achieving high-quality image quality by securing excellent color conversion characteristics and high fluorescence efficiency, and a display device including a color conversion layer produced therefrom. Background technique [0002] The recent display industry is undergoing a drastic change from CRT (Cathode Ray Tube) to flat panel displays represented by PDP (Plasma Display Panel), OLED (Organic Light Emitting Diode), and LCD (Liquid Crystal Display). Among them, LCDs are widely used in image display devices used in almost all industries, and the range of applications thereof continues to expand. [0003] LCD adjusts the transmittance while the white light generated by the backlight unit passes through the liquid crystal unit, and realizes full color by mixing the three primary colors that pass through the red (Red), green (Green), and blue (Blue) color filters...
