Abstract
There is provided a photonic crystal light emitting device including: a substrate; a plurality of nano rod light emitting structures formed on the substrate to be spaced apart from one another, each of the nano rod light emitting structures including a first conductivity type semiconductor layer, an active layer and a second conductivity type semiconductor layer; and first and second electrodes electrically connected to the first and second conductivity type semiconductor layers, respectively, wherein the nano rod light emitting structures are arranged with a predetermined size and period so as to form a photonic band gap for light emitted from the active layer, whereby the nano rod light emitting structures define a photonic crystal structure. In the photonic crystal light emitting device, the nano rod light emitting structures are arranged to define a photonic crystal to enhance light extraction efficiency.
