Abstract:
1. A nitride semiconductor light-emitting diode, comprising: a nitride semiconductor light-emitting chip including an active layer for outputting polarized light, the active layer having a non-polar plane or a semi-polar plane as a growth plane; a first light-transmissive member for transmitting light from the active layer, the first light-transmissive member being arranged at a side surface of the nitride semiconductor light-emitting chip, the side surface being located in a direction perpendicular to a polarization direction of the polarized light; and a wavelength converting member for converting a wavelength of the polarized light which has emitted from the active layer; and wherein: the first light-transmissive member includes a light-transmissive substrate and a plurality of particles, the plurality of particles have a refractive index different from that of the light-transmissive substrate, the first light-transmissive member includes the plurality of particles at not less than 0.4% by weight and not more than 15% by weight, the plurality of particles are formed of at least one material selected from the group consisting of TiO the first light-transmissive member does not include a fluorescent material, the wavelength converting member contains a fluorescent material, the wavelength converting layer is plate-like, the plate-like wavelength converting layer covers the nitride semiconductor light-emitting chip, the first-transmissive member is not interposed between the nitride semiconductor light-emitting chip and the plate-like wavelength converting layer, when viewed in a cross-sectional view of the nitride semiconductor light-emitting diode, and the plate-like wavelength converting layer is parallel to the active layer, when viewed in a cross-sectional view of the nitride semiconductor light-emitting diode.
