Document Type and Number:
Japanese Patent JP4558656
Kind Code:
B2
Abstract:
The invention relates to a nitride light emitting device including first and second conductivity type nitride layers and a plurality of active regions emitting light of different wavelength. The active regions are sequentially formed between the first and the second conductivity type nitride layers. The active regions include at least one first active region having a plurality of first quantum barrier layers and quantum well layers, and a second active region emitting light of a wavelength larger than that of the first active region.
