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.
