Abstract:
There is provided a light emitting device which makes it possible to reduce optical loss and improve brightness by increasing a ratio of fluorescent light that is not reabsorbed by a light emitting element while decreasing a ratio of scattered light that is reabsorbed by the light emitting element. Individual faces forming outer faces of the light emitting element 2 are in contact with a bonding member 3 or sealing member 4. The bonding member 3 and the sealing member 4 contain a fluorophor. Emitted light emitted from the faces of the light emitting element 2 is transformed into fluorescent light by the fluorophor. Therefore, the ratio of scattered light that is not transformed from the emitted light into the fluorescent light can be decreased while the ratio of fluorescent light is increased.
