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.
Claims24
Alight emitting device having a first electrode layer, a light emissive layer, and a second electrode layer, said layers being deposited on a transparent substrate to form a planar light emitting element region on said transparent substrate, comprising:
- a light transmitting region for transmitting out light having been emitted from said light emitting element region and having been propagated through said transparent substrate,
- wherein said light transmitting region is formed at a region other than a region opposite to said light emitting element region on a surface of said transparent substrate.
A light emitting device comprising a first electrode layer, a light emissive layer, and a second electrode layer, said layers being deposited on a transparent substrate to form a planar light emitting element region on said transparent substrate, wherein
- on a surface of said transparent substrate, a display region is formed at a region opposite to said light emitting element region, and in addition to said display region, further formed is a light transmitting region for transmitting out light having been emitted from said light emitting element region and having been propagated through said transparent substrate.
Alight emitting device having a first electrode layer, a light emissive layer, and a second electrode layer, said layers being deposited on a first transparent substrate to form a planar light emitting element region on said first transparent substrate, comprising:
- a second transparent substrate mounted on said first transparent substrate;
- and
- a light transmitting region for transmitting out light having been emitted from said light emitting element region,
- wherein said light transmitting region is formed at a region other than a region opposite to said light emitting element region on a surface of said second transparent substrate.
