Claims37
A light-emitting device, comprising:
- first and second semiconductor layers;
- a light-emitting layer between the first and second semiconductor layers;
- a first electrode pattern layer on the first semiconductor layer, and
- a second electrode pattern layer on the second semiconductor layer, wherein the second electrode pattern layer includes an electrode body and a plurality of branched electrodes extending from the electrode body toward the first electrode pattern layer.
