Abstract

A highly reliable organic electroluminescence device and a manufacturing method includes at least one organic electroluminescence element, a structure, a to-be-covered portion and a passivation film. On a substrate, the organic electroluminescence element includes an anode, an organic layer including an organic light emitting layer, and a cathode. The structure is disposed on the substrate, and thickness of the structure is greater than that of the organic electroluminescence element. The to-be-covered portion is disposed at a step bottom portion of the structure and is formed such that the curvature radius of the cross-sectional shape of the to-be-covered portion at the step bottom portion is at least 0.3 micrometers. The passivation film covers the organic electroluminescence element, the structure and the to-be-covered portion.
