Abstract:
1. A semiconductor light emitting device comprising: a first conductive layer; a first semiconductor layer of a first conductivity type; a second semiconductor layer of a second conductivity type, the second semiconductor layer being provided between the first conductive layer and the first semiconductor layer; a light emitting part provided between the first semiconductor layer and the second semiconductor layer; and a second conductive layer being in contact with the second semiconductor layer and the first conductive layer, the second conductive layer being provided between the second semiconductor layer and the first conductive layer, the first conductive layer including a polycrystal having a first average grain diameter, the first conductive layer being transmittable with respect to light emitted from the light emitting part, and the second conductive layer including a polycrystal having a second average grain diameter of 150 nanometers or less, the second average grain diameter being smaller than the first average grain diameter, and the second conductive layer being transmittable with respect to the light.
