Light-emitting diode

A light-emitting diode, comprising:

• a semiconductor epitaxial structure including a first semiconductor layer, a second semiconductor layer disposed over the first semiconductor layer, an active layer disposed between the first and second semiconductor layers;
• a first electrode electrically coupled to the first semiconductor layer;
• and
• a second electrode disposed over and electrically coupled to said second semiconductor layer;
• wherein:
• the first electrode includes a plurality of first sub-electrodes;
• the second electrode includes a plurality of second sub-electrodes;
• and
• any two adjacent first sub-electrodes and/or second sub-electrodes have a same projection distance;
• wherein:
• the first electrode and/or second electrode include(s) six sub-electrodes forming a minimal unit of closely-packed hexagonal structure;
• the six sub-electrodes are composed of one or more of the first sub-electrodes, the second sub-electrodes, or a combination of the first sub-electrodes and the second sub-electrodes.
