Abstract
An ultraviolet light emitting diode is provided to comprise an n-type semiconductor layer disposed on a substrate; light emitting elements disposed on the n-type semiconductor layer, each comprising an active layer and a p-type semiconductor layer; an n-type ohmic contact layer contacting the n-type semiconductor layer around the micro light emitting elements; p-type ohmic contact layers contacting the p-type semiconductor layers, respectively; an n-bump electrically connecting to the n-type ohmic contact layer; and a p-bump electrically connected to the p-type ohmic contact layers, wherein each of the n-bump and the p-bump is disposed across over a plurality of micro light emitting elements. The micro light emitting elements may be arranged over a wide area of the substrate, and thus light output can be improved and a forward voltage may be lowered, in addition, the n-bump and the p-bump may be formed relatively widely.
