PHOTOSENSITIVE RESIN COMPOSITION, CURED FILM, BANK FOR PARTITIONING LIGHT-EMITTING LAYER IN ORGANIC EL ELEMENT, SUBSTRATE FOR ORGANIC EL ELEMENT, ORGANIC EL ELEMENT, METHOD OF FORMING CURED FILM, METHOD OF PREPARING BANK, AND METHOD OF MANUFACTURING ORGANIC EL ELEMENT

摘要

Provided are a photosensitive resin composition capable of forming a cured film having low gas emission; a cured film formed using the photosensitive resin composition; a bank for partitioning a light-emitting layer in an organic EL element; a substrate for an organic EL element, and an organic EL element, comprising the bank; a cured film using the photosensitive resin composition; a method of preparing a bank for partitioning a light-emitting layer in an organic EL element; and a method of manufacturing an organic EL element using a substrate for an organic EL element comprising the bank. Specifically, the photosensitive resin composition comprises: (A) an alkali-soluble resin; (B) a photocurable monomer; (C) a photopolymerization initiator; and (D) a multi-functional crosslinkable compound having multiple epoxy groups or oxetanyl groups in one molecule, wherein the alkali-soluble resin (A) contains a cardo skeleton-bearing resin, and a compound having an epoxy equivalent weight or an oxetanyl equivalent weight of 50-350 g/eq is used as the multi-functional crosslinkable compound (D).;COPYRIGHT KIPO 2018
