Abstract
The purpose is to provide an organic EL display device which has good sensitivity and is free from the occurrence of luminance decrease or pixel shrinkage, thereby having excellent long-term reliability. In order to achieve the above-described purpose, provided is the following configuration. Namely, an organic EL display device wherein an insulating layer formed on a first electrode is a cured film obtained by curing a photosensitive resin composition; and the residual amount of acid anhydrides contained in the cured film is from 0.003 to 0.04 (inclusive) when the residual amount of aromatic rings contained in the cured film is taken as 1 (the reference value).
