Abstract:
A vertical type light emitting element is disclosed. The vertical type light emitting element includes: a color conversion electrode part including a first electrode pad and a color conversion layer; a reflective electrode part including a second electrode pad and a reflective layer; and a light emitting semiconductor part interposed between the color conversion electrode part and the reflective electrode part. The color conversion electrode part further includes an electrically conductive light transmissive plate. The first electrode pad and the color conversion layer are interposed between the light transmissive plate and the upper surface of the light emitting semiconductor part. Roughnesses are formed on the upper surface of the light emitting semiconductor part bordering the color conversion electrode part to increase the amount of light entering the color conversion electrode part through the light emitting semiconductor part.
