RADIATION-SENSITIVE COMPOSITION, INSULATING FILM AND ORGANIC EL DISPLAY ELEMENT

摘要

According to the present invention, there are provided an insulating film for an organic EL element, which has sufficiently low water permeability and a good sectional form and whose reactivity with a basic material and an electrode made from a metal having a low work function is suppressed, an insulating film for an organic EL element, which enables the formation of a through hole or U-shaped cavity therein and has excellent flattening performance, high transparency and high resistance to a resist stripper, and a radiation sensitive resin composition for forming the insulating film.An organic EL display element having this insulating film is free from an emission failure and has sufficiently long luminance half-life period and excellent reliability.The above composition comprises an alkali-soluble resin which may have an epoxy group and a 1,2-quinonediazide compound.
