Patent ID: 8373179

Claim:
A light-emitting diode (LED) chip, comprising: a substrate; a semiconductor device layer disposed on the substrate; a current blocking layer disposed on the semiconductor device layer and having a plurality of openings or notches; a current spread layer covering the current blocking layer and electrically connected to the semiconductor device layer through the plurality of openings or notches; a first electrode disposed on the current spread layer, wherein the first electrode does not overlap with the plurality of openings or notches; and a second electrode disposed on the semiconductor device layer, wherein the current blocking layer, the current spread layer, the first electrode and the second electrode are located on one side of the semiconductor device layer opposite to the substrate, wherein the first electrode extends along a direction toward the second electrode, and a first group and a second group of the openings or notches are distributed at two sides of the first electrode, and wherein the plurality of openings or notches comprise bar-shape slits not parallel with the first electrode.
