Patent ID: 7064357

Claim:
A nitride compound semiconductor light emitting device comprising: a GaN substrate having a (0001) plane whose crystal orientation is tilted away from a <0001> direction in a <11-20> or <1-100> direction by an angle which is equal to or greater than 0.05° and which is less than 2°, and a n-type layer containing a nitride compound semiconductor located above the GaN substrate, and an active layer containing a nitride compound semiconductor located above the GaN substrate, and an acceptor doping layer containing a nitride compound semiconductor comprising Ga x In y Al 1−(x+y) N (where 0≦x≦1; 0≦y≦1; and 0≦x+y≦1) located above the GaN substrate, wherein the GaN substrate and the active layer are formed so as to be apart from each other by a distance which is equal to or greater than about 1 μm.
