Assignee: SEOUL VIOSYS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A light emitting device, comprising:
a short wavelength light emitting region;
a long wavelength light emitting region; and
a transparent electrode layer combining the short wavelength emitting region and the long wavelength light emitting region, wherein:
the short wavelength light emitting region includes a first structure of a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer,
the long wavelength light emitting region includes a second structure of a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer,
the transparent electrode layer is in contact with a semiconductor layer of at least one of the short wavelength light emitting region or the long wavelength light emitting region,
the active layer of the long wavelength light emitting region contains more Indium (In) than the active layer of the short wavelength light emitting region, and
the short wavelength light emitting region emits light of a shorter wavelength than that of light emitted from the long wavelength light emitting region;

wherein the light emitting device includes no phosphor.
