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).
