Abstract
A light emitting element includes: a semiconductor stack structure including: a first semiconductor layer of a first conductivity type, which, in a top plan view, has a first portion, and a second portion within the first portion, a second semiconductor layer of a second conductivity type disposed on the second portion, and an active layer. The first portion has a peripheral portion positioned at a periphery of the second portion, and a plurality of extended portions extending from the peripheral portion towards the second portion in a top plan view. An insulation layer covers the semiconductor stack structure and has first through holes in the extended portions and a second through hole above the second semiconductor layer. A first electrode is electrically connected to the first semiconductor layer at the first through holes. A second electrode is electrically connected to the second semiconductor layer at the second through hole.
