Title: ORGANIC EL DISPLAY DEVICE
Abstract:
This organic EL display device is configured such that a photosensitive resin composition containing (A) an alkali-soluble resin, (B) a coloring agent, (C) a radically polymerizable compound and (D) a photopolymerization initiator is arranged in a planarization layer and/or a pixel division layer in an organic EL element that is configured of at least a substrate, a first electrode, a second electrode, light emitting pixels, the planarization layer and the pixel division layer. The alkali-soluble resin (A) is (A-1) an alkali-soluble resin having a carboxyl group; and with respect to a cured product obtained by curing the above-described photosensitive resin composition, the total content of metal elements and/or halogen elements in the nonvolatile components is from 1 × 1017 atom/cm3 to 1 × 1022 atom/cm3 (inclusive) as determined by time-of-flight secondary ion mass spectrometry.
