Abstract: A light emitting element includes a first surface corresponding to an end of the light emitting element, a second surface corresponding to another end of the light emitting element, a first semiconductor layer adjacent to the first surface, the first semiconductor layer including a first type of semiconductor, a second semiconductor layer adjacent to the second surface, the second semiconductor layer including a second type of semiconductor different from the first type of semiconductor, and an active layer disposed between the first semiconductor layer and the second semiconductor layer. An area of the first surface is larger than an area of the second surface, and a distance between the first surface and the second surface is shorter than a length defined by the first surface.
