Abstract

See full text

A semiconductor light emitting device includes a structural body, a first electrode layer, and a second electrode layer. The structural body includes a first semiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type, and a light emitting layer between the first and second semiconductor layers. The first electrode layer includes a metal portion, plural first opening portions, and at least one second opening portion. The metal portion has a thickness of not less than 10 nanometers and not more than 200 nanometers along a direction from the first semiconductor layer toward the second semiconductor layer. The plural first opening portions each have a circle equivalent diameter of not less than 10 nanometers and not more than 1 micrometer. The at least one second opening portion has a circle equivalent diameter of more than 1 micrometer and not more than 30 micrometers.
