A radiation-sensitive resin composition which comprises an alkali-soluble resin having or not having an epoxy group and a 1,2-quinonediazide compound; an insulating film formed from the radiation-sensitive resin composition; and an organic EL display element having the insulating film. The insulating film has saisfactorily low water permeability, has a cross section of good shape, and is suppressed in the reactivity with a basic material and an electrode comprising a metal having a low work function, and further, is capable of forming a through hole or a pothole, is excellent in capability of becoming flattened, has high transparency, and has high resistance to a resist-releasing solution. The organic EL display element having the insulating film is free from the failure in light emission, has saisfactorily long half-life of brightness, and is excellent in reliability. |
