Patent ID: 6891203

Claim:
A light emitting device, comprising: a light-emitting element comprising a Group III nitride compound semiconductor and including a light-emitting layer emitting light with an emission peak wavelength in an ultraviolet region and light with an emission peak wavelength in a visible region; and a fluorescent material excited by said light in the ultraviolet region to emit light with a wavelength different from that of said excitation light, wherein the light-emitting layer includes a region of Al x1 Ga 1-x1-x2 In x2 N(0<x1<1, 0<x2<1, x1>x2) emitting the light in the ultraviolet region and a region of Al y1 G a1-y1-y2 In y2 N(0<y1<1, 0<y2<1, y1<y2) emitting the light in the visible region.
