Abstract
A transparent electrode layer, an organic EL layer, and a metallic electrode layer are stacked on top of each other in layers on the lower surface of a transparent substrate to form a planar light emitting element region in a light emitting device. A light beam which is emitted from the light emitting element region and incident on the transparent substrate is transmitted out from a display region as well as a light transmitting region formed near an edge of the transparent substrate. Thus, the light emitting device is enabled to facilitate fabrication and make an effective use of the entire surface of the transparent substrate as the light transmitting region.
