Micro light-emitting element, micro light-emitting display device including the same, and method for manufacturing the same

Abstract

A micro light-emitting element is provided. The micro light-emitting element includes a first-type semiconductor having a bottom surface and a light-emitting layer disposed on the first-type semiconductor. The micro light-emitting element also includes a second-type semiconductor disposed on the light-emitting layer and an intrinsic semiconductor disposed on the second-type semiconductor and made of the same material as the second-type semiconductor. The intrinsic semiconductor has a top surface relative to the bottom surface. The sidewalls of the first-type semiconductor, the light-emitting layer, the second-type semiconductor, and the intrinsic semiconductor form a continuous side surface, and the side surface connects the bottom surface to the top surface. The micro light-emitting element further includes a metal reflecting layer disposed on the side surface and laterally covering the sidewalls of the intrinsic semiconductor and the portion of the second-type semiconductor that is adjacent to the intrinsic semiconductor.
