Patent ID: 11967606
Assignee: NICHIA CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A light-emitting device comprising:
a first light-emitting element portion comprising:
an n-side nitride semiconductor layer,
a first light-emitting layer disposed on the n-side nitride semiconductor layer, and
a first p-side nitride semiconductor layer disposed on the first light-emitting layer;

a second light-emitting element portion comprising:
a second light-emitting layer disposed on the n-side nitride semiconductor layer, and
a second p-side nitride semiconductor layer disposed on the second light-emitting layer;

an n-side electrode connected to the n-side nitride semiconductor layer;
a first p-side electrode disposed on the first p-side nitride semiconductor layer via an upper n-type semiconductor layer disposed on the first p-side semiconductor layer; and
a second p-side electrode connected to the second p-side nitride semiconductor layer; wherein:
a composition of the second light-emitting layer is different from a composition of the first light-emitting layer.
