Abstract
A display apparatus comprising an interlayer insulation film provided on a substrate in the condition of covering recesses and projections due to a wiring on the substrate, and an organic EL device provided on the interlayer insulation film, wherein the interlayer insulation film comprises a flattening insulation layer formed in the condition of embedding the wiring, and a coat layer formed in the condition of covering the surface of the flattening insulation layer. The flattening insulation layer is a coat film made from an organic compound-containing material, for example, spin on glass or a resin material, and the coat layer is a film of an inorganic material.
