Abstract
A light emitting device has a substrate and a light-emitting section formed on the substrate. The light-emitting section includes a light-emitting layer in which light is generated by electro-luminescence, first and second electrodes used to apply electric charges to the light-emitting layer, and first and second dielectric multi-layered films between which the light-emitting layer is interposed. The first and second electrodes are disposed to avoid overlap with a light-emitting region in the light-emitting layer as viewed from a light emitting direction.
