Patent ID: 8288755

Claim:
A light-emitting element comprising: a buffer layer formed on a substrate; photonic crystal patterns and a pad pattern formed on the buffer layer, wherein each of the pad pattern and the photonic crystal patterns is made of a metal material, and the pad pattern is physically connected to the photonic crystal patterns; a light-emitting structure comprising a first conductive pattern of a first conductivity type, a light-emitting pattern, and a second conductive pattern of a second conductivity type sequentially stacked on the buffer layer; a first electrode electrically connected to the first conductive pattern; and a second electrode electrically connected to the second conductive pattern, wherein the first conductive pattern is wider than the second conductive pattern and the light-emitting pattern and the first conductive pattern has a protruding portion extending in a lateral direction, and the pad pattern is disposed under the protruding portion of the first conductive pattern.
