ORGANIC EL DISPLAY DEVICE AND PHOTOSENSITIVE RESIN COMPOSITION

WIPO Patent Application WO/2021/182499

A1

An organic EL display device which comprises, on a substrate, a planarization layer, a first electrode, a pixel division layer, a light emitting pixel and a second electrode, wherein: the planarization layer and/or the pixel division layer contains zirconium nitride particles; and the crystallite size of the zirconium nitride particles as calculated from the half width of the peak associated with the (111) plane in the X-ray diffraction spectrum as obtained using a CuKα ray as the X-ray source is from 5 nm to 20 nm. The present invention provides: an organic EL display device which has excellent visibility, while being suppressed in display defects; and a photosensitive resin composition which is applicable to an insulating layer of the organic EL display device, while exhibiting excellent storage stability. The present invention enables the achievement of a cured film that has high sensitivity and high visible light blocking performance, while being free from opening residue.
