Abstract: The present invention provides an organic EL image display device including a light emitting element substrate, and a circularly polarizing plate, in which the light emitting element substrate includes a reflecting layer and an organic electroluminescent layer on the reflecting layer, the reflecting layer, the organic electroluminescent layer, and the circularly polarizing plate are arranged in this order, a polarization separation layer is provided between the organic electroluminescent layer and the circularly polarizing plate, the polarization separation layer includes a polarization separation region that reflects light of one polarization state in light emitted from the organic electroluminescent layer, and transmits light of another polarization state, and a visible light transmission region, the polarization separation region is formed of a layer formed by immobilizing a cholesteric liquid crystalline phase, and a positive C region-containing layer is provided between the organic electroluminescent layer and the circularly polarizing plate. The organic EL image display device according to the present invention has high brightness and little light leakage and blurring at the time of oblique observation.

Abstract: A black resin film is produced by applying a photosensitive resin composition containing a black pigment, an alkali-soluble polymer compound, an ethylenic unsaturated bond-containing compound and α-aminoalkylphenone or α-hydroxyalkylphenone as a photopolymerization initiator, to a substrate; and subjecting the composition to exposure, development and post-exposure. The post-exposure is performed from both side with 1,300 mJ/cm2 or more in terms of i line.
