Document Type and Number:
WIPO Patent Application WO/2022/224779
Kind Code:
A1
Abstract:
Provided is an organic EL display device that exhibits high luminance and high color reproducibility and has a color filter which exhibits excellent pixel adhesion and excellent pixel linearity in a development step even in a case of high colorant concentration. This organic EL display device comprises an organic EL layer and a color filter on a silicon substrate in which a driving element is formed. The color filter has pixels including specific red, green, and blue pixels. Each of the pixels is a cured product of a photosensitive coloring composition which contains a specific colorant (A), a photopolymerizable monomer (B), a photopolymerization initiator (C), and a resin (D). The photopolymerizable monomer (B) includes a compound represented by formula (1), and the photopolymerization initiator (C) includes an oxime ester-based photopolymerization initiator. Formula (1): [CH2=CHC (=O)-(OCmH2m)n-OCH2]3-CCH2CH3 (Signs in formula (1) are according to those described in the description.)
