Proposed is a dual emission LED chip that emits light to the upper and lower sides of a PN junction, wherein the duel emission LED chip uses the electroluminescent effect of the PN junction including a P layer and an N layer provided below the P layer, and characterized in that the dual emission LED chip emits light in the upward direction of the P layer and the downward direction of the N layer. The dual emission chip can be applied as a single chip to a field requiring dual emission, thereby enabling miniaturization of applied equipment, and increases power efficiency, thereby reducing manufacturing costs. In addition, as the dual emission LED chip can be manufactured through a batch process, a separate packaging process is not required.
