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

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 includes quantum dots; a resin; a light diffusing agent having a primary particle size of 80 nm to 200 nm and a secondary particle size of 120 nm to 250 nm; and a solvent. The photosensitive resin composition includes quantum dots; a binder resin; a photopolymerizable monomer; a photopolymerization initiator; a light diffusing agent having a primary particle diameter of 80 to 200 nm and a secondary particle diameter of 120 to 250 nm; and 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, the color filter is used in a liquid crystal display (LCD), an optical filter of a camera, and the like. Color filters are fabricated by coating fine regions colored with more than three colors on a charge-coupled device or transparent substrate. A colored film can generally be produced using a dyeing method, a printing method, a pigment dispersion method, an inkjet method, or the like. [0003] Dyeing involves forming an image on a substrate with a coloring agent such as natural photosensitive resin (eg, gelatin, etc.), ...
