example 7 to example 13 and comparative example 5 to comparative example 8
[0298] Each of the photosensitive resin compositions according to Examples 7 to 13 and Comparative Examples 5 to 8 was prepared to have the compositions in Table 4 and Table 5, respectively, using the following components.
[0299] (1) The photopolymerization initiator is dissolved in a solvent (PGMEA). A photopolymerizable monomer, a binder resin, a thiol-based additive, and a fluorine-based surfactant were respectively added thereto and sufficiently dissolved therein. Subsequently, the light-diffusing agent dispersion was added thereto, and the obtained mixture was stirred until uniformly dispersed.
[0300] (2) The quantum dot powder and the dispersant were dissolved in a solvent (cyclohexyl acetate), and then mixed with a binder resin to prepare a quantum dot-binder resin mixed solution.
[0301] (3) The above solution (1) was mixed with the quantum dot-binder resin mixed solution (2) and sufficiently stirred for 30 minutes, and the mixture was filtered three times to rem...

Abstract
The present invention provides a curable composition, a photosensitive resin composition, a photosensitive resin film, a color filter, and a method of manufacturing a pixel for a color filter. The curable composition comprises quantum dots; resin; a light diffusing agent having a primary particle diameter of 80 nm to 200 nm and a secondary particle diameter of 120 nm to 250 nm; and a solvent. Thephotosensitive resin composition contains quantum dots; binder resin; a photopolymerizable monomer; a photopolymerization initiator; a light diffusing agent having a primary particle diameter of 80 nmto 200 nm and a secondary particle diameter of 120 nm to 250 nm; and a solvent. The color filter is produced using the curable composition or the photosensitive resin composition.
Description
technical field [0001] The present disclosure relates to a curable composition comprising quantum dots, a method of manufacturing a pixel for a color filter using the curable composition, and a color filter manufactured using the curable composition . The present disclosure also relates to a photosensitive resin composition, a photosensitive resin film and a color filter using the photosensitive resin composition. Background technique [0002] Generally, color filters are used for liquid crystal displays (LCDs), optical filters for cameras, and the like. Color filters are manufactured by coating a charge-coupled device or transparent substrate with fine areas colored with more than three colors. Colored films can generally be produced by a dyeing method, a printing method, a pigment dispersion method, an ink jet method, or the like. [0003] Dyeing involves forming an image on a substrate with colorants such as natural photosensitive resins (eg, gelatin, etc.), amine-modi...
