Abstract

The invention provides an electro-optical device capable of improving a high light projection efficiency to the outside while maintaining sealing ability for providing high recognition of vision. An organic electroluminescence display can include a light permeable substrate, and an organic electroluminescence element having a luminous layer and positive hole transfer layer interposed between a pair of electrodes. Additionally, a low refractivity film having a lower refractivity than the substrate, and a seal layer for blocking the air from invading from the substrate side to the organic electroluminescence element are laminated between the substrate and electrode of the organic electroluminescence element.
