AI Technical Summary

Problems solved by technology

The size of the scattering particles used at this time ranges from a few microns to hundreds of microns (μm). If the particle size is too large, the quality of the coating film will deteriorate.
In particular, when the size of the scattering particles is several hundred microns (μm), the thickness of the coating film must be at least fixed and scattered, resulting in an increase in the overall thickness of the color filter.
[0015] These patents expect to use quantum dots and scattering particles to improve the light efficiency of color filters, but a multi-layer structure is used, and the effect is not sufficient because the average particle diameter of the scattering particles used is on the order of micrometers (μm)

[0119] Manufacturing example 1: Synthesis of green quantum dots A-1 with CdSe (core) / ZnS (shell) structure

[0120] CdO (0.4 mmol), zinc acetate (4 mmol), oleic acid (5.5 mL) and 1-octadecene (20 mL) were put into a reactor, and heated at 150° C. for reaction. Afterwards, in order to remove the acetic acid produced by the substitution of zinc with oleic acid, the aforementioned reactants were placed under a vacuum of 100 mTorr for 20 minutes.

[0121] After that, after heating to 310° C. to obtain a transparent mixture, which was maintained at 310° C. for 20 minutes, 0.4 mmol of Se powder and 2.3 mmol of S powder were dissolved in 3 mL of trioctylphosphine (trioctylphosphine) of Se and S solution is quickly injected into the Cd(OA) 2 (Cadmium oleate) and Zn(OA) 2 (Zincoleate) solution in the reactor. The mixture thus obtained was grown at 310° C. for 5 minutes, and then the growth was stopped in an ice bath.

Abstract

The invention relates to a self emission type photosensitive resin composition, a color filter manufactured by the self emission type photosensitive resin composition, and an image display device containing the color filter. More specifically, the invention relates to the self emission type photosensitive resin composition including quantum dots, scattering particles, a polymerization compound, a polymerization initiator, alkaline solubility resin, and a solvent, and the image display device containing the color filter manufactured by the self emission type photosensitive resin composition. The color filter eliminates a decrease in light efficiency of the conventional color filter. When the color filter is introduced into the image display device, features and high light efficiency reappear by maintaining excellent colors and color display is ensured so that high-quality bright-colored image quality is achieved.

Description

technical field [0001] The present invention relates to a self-luminous photosensitive resin composition capable of realizing high-quality image quality by securing excellent color reproduction characteristics and high light efficiency, a color filter and an image display device manufactured from the self-luminous photosensitive resin composition . Background technique [0002] The display industry has rapidly changed from CRT (cathode-ray tube) to flat panel displays represented by PDP (plasma display panel), OLED (organic light-emitting diode), LCD (liquid-crystal display) and so on. Among them, LCD is widely used in image display devices used in almost all industries due to its advantages of thinness, lightness, excellent resolution, and low power consumption, and it is expected that there will be a large market expansion in the future. [0003] For LCD, the white light generated by the light source passes through the liquid crystal unit while adjusting the light transmi...
