Abstract:
1. A light emitting element comprising: a substrate; a light emitting layer formed on said substrate to emit light, wherein said light emitting layer includes a first semiconductor layer of a first conductivity type, an active layer formed on said first semiconductor layer to emit the light and a second semiconductor layer of a second conductivity type formed on said active layer; a first electrode contacting said second semiconductor layer; and a second electrode contacting said first semiconductor layer, said first electrode comprising: wherein each of said active layer and said second semiconductor layer has a square shape, said first electrode has a round shape, both of said active layer and said second semiconductor layer are located at a place which is above the center of said substrate such that a center line drawn vertically through said substrate will pass through said active layer and said second semiconductor layer, and said second electrode is located at an edge portion of said substrate.
