摘要： A method of manufacturing a light emitting element includes: providing a first light emitting part and a second light emitting part, the first light emitting part comprising a first base member and a first semiconductor layered body, the second light emitting part comprising a second base member and a second semiconductor layered body; bonding the first and second light emitting parts to each other such that the first base member and the second base member are disposed between the first semiconductor layered body and the second semiconductor layered body; disposing a light reflecting member to cover the bonded first and second light emitting parts; removing a portion of the light reflecting member to expose surfaces of the first and second base members; and disposing a wavelength conversion member on the exposed surface of the first base member and the exposed surface of the second base member.

摘要： A light-emitting device includes a semiconductor stacked body having first and second semiconductor layers. The second semiconductor layer includes conductive portions contacting a second conductive layer and having island configurations. The conductive portions are disposed in a first region, a second region, a third region, and a fourth region. The first region is positioned at a periphery of a first corner of the semiconductor stacked body. The second region is positioned at a periphery of a second corner of the semiconductor stacked body. The third region is positioned at a periphery of a third corner of the semiconductor stacked body. The fourth region is positioned at a periphery of a fourth corner of the semiconductor stacked body. A density of the conductive portions disposed in the first region is greater than densities of the conductive portions disposed in the second region, the third region, and the fourth region.
