Abstract
There is provided a highly sensitive colorant-containing photosensitive resin composition for use in the formation of organic EL element barrier ribs. In one embodiment, the photosensitive resin composition for an organic EL element barrier rib comprises: (A) a binder resin; (B) at least one low molecular weight organic compound having a molar volume of 130 cm3/mol or less and being selected from the group consisting of aromatic carboxylic acids and compounds each having a plurality of phenolic hydroxyl groups; (C) a radiation sensitive compound; and (D) a colorant selected from the group consisting of black dyes and black pigments.

A photosensitive resin composition for a light shielding barrier rib of an organic EL element comprising:
- (A) a binder resin;
- (B) at least one low molecular weight organic compound having a molar volume of 130 cm3/mol or less and being selected from the group consisting of aromatic carboxylic acids and compounds each having a plurality of phenolic hydroxyl groups;
- (C) a radiation sensitive compound;
- and
- (D) a colorant selected from the group consisting of black dyes and black pigments,
- wherein the binder resin (A) comprises (c) an aqueous alkaline solution-soluble resin having an epoxy group and a phenolic hydroxyl group, and
- the amount of the colorant (D) contained in the photosensitive resin composition is 1 part by mass to 70 parts by mass with respect to 100 parts by mass of the total of the binder resin (A), the low molecular weight organic compound (B), the radiation sensitive compound (C), and the colorant (D).
