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 photopolymerization initiator. Formula (1): [CH2═CHC(═O)—(OCmH2m)n—OCH2]3—CCH2CH3 (Signs in formula (1) are according to those described in the description.)

Abstract: An organic electroluminescent display device includes a light-emitting device substrate assembly including a light-emitting device substrate assembly including a drive circuit board and light-emitting devices positioned on the drive circuit board, a color filter including red colored pixels, green colored pixels, and blue colored pixels at positions corresponding to the light-emitting devices of the light-emitting device substrate assembly, and a light-shielding layer formed such that the light-shielding layer does not overlap the light-emitting devices and is straddling a boundary between the colored pixels. The drive circuit board includes a semiconductor substrate having a drive circuit formed therein, and each of the light-shielding layer and the color filter has a surface oriented toward the light-emitting devices such that the surface of the light-shielding layer is flush with the surface of the color filter or closer to the light-emitting devices than the surface of the color filter.
