Method for sealing organic el element

Abstract

A method for sealing an organic EL element, the method including: a step in which a stress relaxation layer is formed by at least applying a polymer material that contains an organic group in the structure to a base material, on which an organic EL element is provided, so as to cover the organic EL element; and a step in which a barrier layer is formed by at least applying an inorganic material to the stress relaxation layer, thereby forming a multilayer sealing film that comprises the stress relaxation layer and the barrier layer.
