Patent ID: 8417072

Claim:
A light emitting device comprising: a substrate; a light emitting layer; a first conductivity type layer provided between the substrate and the light emitting layer; a first distributed Bragg reflector layer provided between the first conductivity type layer and the substrate, with first layers and second layers alternately stacked in the first distributed Bragg reflector, the second layers having refractive index different from refractive index of the first layers, the first distributed Bragg reflector layer having a center wavelength substantially same as emission wavelength of emission light from the light emitting layer; a second distributed Bragg reflector layer provided between the light emitting layer and the first distributed Bragg reflector layer, with third layers and fourth layers alternately stacked in the second distributed Bragg reflector layer, the fourth layers having refractive index different from refractive index of the third layers, the second distributed Bragg reflector layer having a center wavelength longer than the center wavelength of the first distributed Bragg reflector layer in a range of 5 nm or more and 20 nm or less, and number of the third layers being smaller than number of the first layers.
