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.
