Patent ID: 10707392

Abstract:
A semiconductor light-emitting element according to the present invention includes a metal layer, a light-emitting layer, a first conductivity type layer and a second conductivity type layer sandwiching the light-emitting layer, and a plurality of contact portions that electrically connects the metal layer and the first conductivity type layer. The semiconductor light-emitting element includesa surface electrode including a pad electrode and a branch-shaped electrode that extends from the pad electrode between the plurality of contact portions. Distances between the contact portions and the surface electrode satisfies the following relational expression: d1>d2>d3, wherein d1 represents a distance between a first contact portion in the periphery of the pad electrode among the contact portions and the pad electrode; d2 represents a distance between the first contact portion and the branch-shaped electrode closest to the first contact portion; and d3 represents a distance between a second contact portion spaced further away from the pad electrode than the first contact portion among the contact portions and the branch-shaped electrode closest to the second contact portion.
