Title:
LIGHT-EMITTING ELEMENT AND LIGHT-EMITTING ELEMENT PACKAGE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2017/135688
Kind Code:
A1
Abstract:
An embodiment of a light-emitting element comprises: a substrate; a first conductive semiconductor layer arranged on the substrate; an active layer arranged on the first conductive semiconductor layer, the active layer comprising a plurality of quantum well layers and a plurality of quantum barrier layers laminated alternately; a second conductive semiconductor layer arranged on the active layer; a contact layer arranged on the second conductive semiconductor layer; a current dispersing layer arranged on the contact layer; and a current blocking layer arranged on the second conductive semiconductor layer, wherein the contact layer and/or the current dispersing layer may be provided to surround at least a part of the current blocking layer such that, when the Miller plane index is 400, the strength of X-ray diffraction beams becomes maximum.
