Abstract: An organic EL display device including a substrate, and a planarization layer, a first electrode, a pixel division layer, a light emitting pixel and a second electrode formed on the substrate, wherein the planarization layer and/or the pixel division layer contain(s) zirconium nitride particles, and a crystallite size of the zirconium nitride particles determined from a half width of a peak derived from a (111) plane in an X-ray diffraction spectrum using a CuKα ray as an X-ray source is 5 nm or more 20 nm or less. Provided are an organic EL display device with excellent visibility and fewer display defects, and a cured film which is excellent in storage stability of a photosensitive resin composition capable of being applied on an insulating layer of the organic EL display device, and which has high sensitivity and high visible light-shielding property and is also free from residue in the opening.

Abstract: The present invention provides a photosensitive composition which can suppress the generation of a development residue on the surface of an electrode and the corrosion of the electrode to form a black pixel division layer, and also can suppress the generation of off-pixel in an organic EL display device comprising the pixel division layer. Disclosed is a photosensitive composition comprising (a) a pigment, (b) a resin having two or more tertiary amino groups in the molecule, and (c) a photosensitive agent, wherein the component (b) contains a resin having a structure represented by the general formula (1).
