RADIATION SENSITIVE RESIN COMPOSITION FOR FORMING INSULATION FILM OF ORGANIC EL DISPLAY ELEMENT, INSULATION FILM FORMED FROM THE SAME AND ORGANIC EL DISPLAY ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a radiation sensitive resin composition for forming an insulation film of an organic EL(electroluminescent) element capable of forming a through hole or a U-shaped recess, excellent in flattening performance and having high transparency and high resistance to a resist removing solution and to provide an insulation film of an organic EL element formed from the composition and an organic EL display element with the insulation film. SOLUTION: The composition contains (a) an epoxy-containing alkali-soluble resin and (b) a 1,2-quinonediazido compound. The insulation film is formed from the composition. The organic EL display element has the insulation film.
