Title:
LIGHT-EMITTING DIODE AND LIGHT-EMITTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/044952
Kind Code:
A1
Abstract:
The present invention relates to a light-emitting diode, comprising an epitaxial structure, a first metal electrode, a second metal electrode, an insulating laminated layer, a metal reflecting layer, a first connecting electrode and a second connecting electrode, wherein the epitaxial structure sequentially comprises, from the lower surface to the upper surface, a first semiconductor layer, a light-emitting layer and a second semiconductor layer; the first metal electrode and the second metal electrode are located on the upper surface of the epitaxial structure; the insulating laminated layer covers part of the epitaxial structure and part of a contact electrode, and comprises a first insulating layer and a second insulating layer, which is located on the first insulating layer; the metal reflecting layer is sandwiched between the first insulating layer and the second insulating layer; the first connecting electrode and the second connecting electrode are located above the insulating laminated layer, and are respectively connected to the first metal electrode and the second metal electrode; and the vertical projection of the first metal electrode and/or the second metal electrode in the horizontal plane does not overlap with the vertical projection of the metal reflecting layer in the horizontal plane. Therefore, the light-emission performance and the reliability of the light-emitting diode can be improved.
