Embodiment 1 to 4、 comparative Embodiment 1 to 4

[0132] Examples 1 to 4, Comparative Examples 1 to 4, and Reference Example 1

[0133] The black photosensitive resin compositions according to Examples 1 to 4, Comparative Examples 1 to 4, and Reference Example 1 were prepared using the following component 1 to have the compositions in the following table.

[0134] (A) Colorant

[0135] (A-1) A pigment dispersion liquid (C1-M-050, Sakata Co.) including carbon black was used. Herein, carbon black is contained within a solid content of 18% by weight of the pigment dispersion.

[0136] (A-2) 300 g of 0.5 mm zirconia beads were placed in a 1 L basket mill with a stirrer and cooling jacket, and 300 g of bromide and 380 g of propylene glycol methyl ether acetate added there. Then, 26g of DISPERBYK-161 (BYK CO., LTD.) as a dispersant, 18g of carbadole-based polymers with a weight average molecular weight of 3,000g / mol, 4g of 4,4'-(9- 4,4'-(9-fluorenylidene)diphenolglycidylether), and 4 g of cetyltrimethylammonium bromide were add...

Abstract

Provided are a black photosensitive resin composition and a light-shielding layer using same, wherein the composition comprises (A) a colorant comprising carbon black and silver halide, (B) a binder resin, (C) a reactive unsaturated compound, (D) a photopolymerization initiator, and (E) a solvent.

Description

technical field [0001] The invention relates to a black photosensitive resin composition and a light-shielding layer using the composition. Background technique [0002] A black photosensitive resin composition must be used for manufacturing color filter display elements, liquid crystal display materials, organic light emitting elements (EL), display panel materials, and the like. For example, color filters (such as color liquid crystal displays and the like) require light-shielding layers on the boundaries between colored layers (such as: red, green, blue, and the like) to enhance display contrast or brightness. chromophore effect. The light-shielding layer can be mainly formed of a black photosensitive resin composition. [0003] Many patents disclose about black photosensitive resin composition. Japanese Patent Early Publication No. 2002-047423 discloses that cobalt oxide is used as a black pigment to realize a black matrix with high blackness and insulating properties...
