Light-emitting element |
摘要 |
A light-emitting element comprises a light-emitting semiconductor stack comprising a first semiconductor layer, a second semiconductor layer on the first semiconductor layer, and a light-emitting layer between the first semiconductor layer and the second semiconductor layer; a plurality of extensions formed on the first semiconductor layer; and a first conductive part and a second conductive part formed on the light-emitting semiconductor stack and respectively electrically connected to the first semiconductor layer and the second semiconductor layer, wherein one of the plurality of extensions is formed beyond a projected area of the second conductive part and not covered by the first conductive part. |
