Abstract
Provided is a nitride semiconductor light-emitting diode having a higher light extraction efficiency and a higher polarization degree. A nitride semiconductor light-emitting diode according to the present invention comprises an active layer generating a polarized light, a first side surface, a second side surface, a third side surface, and a fourth side surface. The first and second side surfaces consist only of a plane including the Z-axis and the Y-axis. The third and fourth side surfaces are perpendicular to the first and second side surfaces and include the X-axis. The third and fourth side surfaces include an inclined surface.
