Claim:
1. A method of producing a light emitting element, comprising: forming an electro-conductive reflection film by coating a composition for the electro-conductive reflection film containing metal nanoparticles and an additive material on a substrate by a wet-coating method, and subsequently drying the composition for the electro-conductive reflection film at 150 to 350° C. and firing or curing the dried composition for the electro-conductive reflection film; disposing a light emitting layer on the electro-conductive reflection film; disposing a transparent electro-conductive film by coating a composition for overcoat containing light transmitting binder, transparent electro-conductive particles and transparent particles on the electro-conductive reflection film by the wet-coating method after forming the electro-conductive reflection film and before forming the light emitting layer, and subsequently firing or curing the composition for overcoat; and forming an adhesion layer between the electro-conductive reflection film and the substrate, and the adhesion layer has a thickness of 0.01 to 0.5 μm.
