Claim Text:
1. A semiconductor light emitting device, comprising: a plurality of semiconductor layers that grows sequentially on a growth substrate, with the plurality of semiconductor layers including a first semiconductor layer having a first conductivity, a second semiconductor layer having a second conductivity different from the first conductivity, and an active layer interposed between the first semiconductor layer and the second semiconductor layer, generating light via electron-hole recombination; a first electrode electrically connected with the first semiconductor layer for supplying electrons to the first semiconductor layer; a second electrode electrically connected with the second semiconductor layer for supplying holes to the second semiconductor layer; a non-conductive distributed bragg reflector interposed between the second electrode and the plurality of semiconductor layers, and coupled to the plurality of semiconductor layers, reflecting the light from the active layer; and a first light-transmitting film interposed between the second electrode and the non-conductive distributed bragg reflector and contacted with both the second electrode and the non-conductive distributed bragg reflector, with the first light-transmitting film having a refractive index lower than an effective refractive index of the non-conductive distributed bragg reflector, wherein the first light-transmitting film has a thickness greater than λ/4 n, wherein λ is a wavelength of light generated in the active layer and n is a refractive index of the first light-transmitting film, wherein the first electrode is provided on the non-conductive distributed bragg reflector, and wherein the device further comprises an electrical connection passing through the first light-transmitting film and the non-conductive distributed bragg reflector thereby electrically connecting the first semiconductor layer with the first electrode.
