1. A light emitting diode, comprising:
a light emitting portion;
a first electrode;
a first reflecting portion comprising conductive material, the first electrode electrically contacting the first reflecting portion to electrically connect the light emitting portion; and
a second electrode electrically connected to the light emitting portion;
wherein the first electrode and the second electrode are configured to receive driving voltages to drive the light emitting portion to emit light; the first reflecting portion is configured to reflect light from the light emitting portion; the first reflecting portion comprises a plurality of first conductive layers and a plurality of second conductive layers; one of the plurality of first conductive layers alternatives with one of the plurality of second conductive layers; and an impedance of each of the plurality of first conductive layers is different from an impedance of each of the plurality of second conductive layers.
