manufacture example 1

[0101] Production Example 1: Synthesis of Photoluminescent Green Quantum Dot Particles A of CdSe (as core) / ZnS (as Shell) Structure

[0102] Put CdO (0.4mmol) and Zinc acetate (4mmol), Oleic acid (5.5mL) and 1-Octadecene (20mL) into the reactor together, heat to 150 °C to carry out the reaction. The above reactants were then placed under a vacuum of 100 mTorr for 20 minutes in order to remove acetic acid produced by the substitution of oleic acid by zinc. Then, heated to 310°C to obtain a clear mixture, maintained at 310°C for 20 minutes, and then filled with Cd(OA) 2 and Zn(OA) 2 A solution of Se and S obtained by dissolving 0.4 mmol of Se powder and 2.3 mmol of S powder in 3 ml of trioctylphosphine was rapidly injected into the solution reactor. After growing the thus obtained mixture at 310° C. for 5 minutes, the growth was interrupted using an ice bath. Then, it was precipitated with ethanol, the quantum dots were separated by a centrifuge, and the remaining magazine...

[0104] Prepare stirrer, thermometer reflux condenser, drip, and flask with nitrogen introduction tube. 45 parts by weight of N-benzyl maleimide, 45 parts by weight of methacrylic acid, 10 parts by weight of tricyclodecyl methacrylate, 4 parts by weight of tert-butyl peroxide-2-ethylhexanoate, 40 parts by weight of propylene glycol monomethyl ether acetate (hereinafter referred to as PGMEA) was charged and mixed with stirring to prepare a monomer dripping liquid. 6 parts by weight of n-dodecyl mercaptan and 24 parts by weight of PGMEA were added, followed by stirring and mixing to prepare a chain transfer agent dripping liquid. Then, after introducing 395 parts by weight of PGMEA into the flask and changing the atmosphere in the flask from air to nitrogen, the temperature of the flask was raised to 90°C while stirring. Next, dripping of the monomer dripping liquid and the chain transfer agent dripping liqu...

Abstract

The present invention relates to a self-luminous photosensitive resin, in particular to a self-luminous photosensitive resin containing photoluminescent quantum dots, a photopolymerization compound, a photopolymerization initiator, an alkaline soluble resin, a UV absorber and a solvent, and a color filter manufactured using the self-luminous photosensitive resin and image display devices.

Description

technical field [0001] The present invention relates to a self-luminous photosensitive resin, a color filter manufactured using the same, and an image display device. Background technique [0002] A color filter is a thin-film optical element that extracts three colors of red, green, and blue from white light and can support tiny pixel units. The size of one pixel is about tens to hundreds of micrometers. The above-described color filter has a structure in which a black matrix layer formed in a predetermined pattern on a transparent substrate in order to block light at a boundary portion between pixels, and a black matrix layer formed in a predetermined pattern for forming each pixel are stacked in this order. A pixel portion in which three primary colors of a plurality of colors (usually, red (R), green (G), and blue (B)) are arranged in a predetermined order. Generally, color filters are prepared by coating three or more colors on a transparent substrate by a dyeing metho...
