PROBLEM TO BE SOLVED: To provide an insulating film for an organic EL device having sufficiently low water permeability and a good cross-sectional shape, a radiation-sensitive resin composition for forming the same, and an organic material having the insulating film. To provide an EL display element. SOLUTION: The radiation-sensitive resin composition contains (a) a novolak resin and (b) a 1,2-quinonediazide compound. The insulating film is formed from the radiation-sensitive resin composition. The organic EL display element has the insulating film. |
