Claim 21:
22. A diode, comprising:
a stack of functional layers including a first semiconductor layer, a second semiconductor layer, and a light emitting layer located between the first semiconductor layer and the second semiconductor layer;
a first electrode disposed on the first semiconductor layer;
a second electrode disposed on the second semiconductor layer; and
a first current blocking region covering at least a portion of the first semiconductor layer, the light emitting layer or the second semiconductor layer; and
a second current blocking region surrounded by the first current blocking region, and a shortest distance between the first current blocking region and the second current blocking region is equal to or less than 50 micrometers;
wherein the first electrode and the second electrode are disposed at the same side of the first semiconductor layer.
