WIPO Patent Application WO/2024/057730
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an organic EL display device exhibiting high sensitivity and excellent reliability. Proposed as a solution is an organic EL display device comprising at least a substrate, a first electrode, a second electrode, a light-emitting layer, a planarization layer, and a pixel dividing layer, wherein: the planarization layer or the pixel dividing layer has a cured product obtained by exposure/developing/curing of either a resin composition A containing a resin (A-1) that has an alkali-soluble group which is protected by a protective group separable by acid and a photoacid generator (B), or a resin composition B containing a resin that contains an alkali-soluble group, a compound (A-2) that has an alkali-soluble group which is protected by a protective group separable by acid, and a photoacid generator (B); and the combined content of metal elements and elemental halogen in the cured product, as measured by time-of-flight secondary ion mass spectrometry, is 1.0×1016 atoms/cm3 to 1.0×1023 atoms/cm3.
