Abstract
A light-emitting diode includes a semiconductor light-emitting stack and a distributed Bragg reflector (DBR) structure. The semiconductor light-emitting stack has a first surface and a second surface opposite to each other. The DBR structure is disposed on one of the first surface and the second surface of the semiconductor light-emitting stack, and includes at least one set of first light-transmitting layers and at least one set of second light-transmitting layers stacked on each other in the first direction. The first light-transmitting layers has interface roughness greater than that of the second light-transmitting layers.
