Document Type and Number:
WIPO Patent Application WO/2019/066339
Kind Code:
A1
Abstract:
Provided is a light emitting diode chip having an improved light extraction efficiency. A light emitting diode chip according to an embodiment comprises: a substrate; a first conductive semiconductor layer arranged on the substrate; a mesa including an active layer and a second conductive semiconductor layer and arranged on a partial region of the first conductive semiconductor layer so as to expose an upper surface of the first conductive semiconductor layer along the edge of the first conductive semiconductor layer; a side surface coating layer (layers) for covering the side surfaces of the mesa; and a reflection structure arranged apart from the side surface coating layer (layers) and arranged on the exposed first conductive semiconductor layer.
