| 摘要 |
Discussed are a nitride semiconductor light emitting device in which a critical angle is increased by rounding corners of a substrate so as to improve light extraction efficiency due to increase in an amount of light generated from the inside thereof and extracted to the outside, and a method for manufacturing the same. The nitride semiconductor light emitting device includes according to an embodiment a buffer layer formed on a substrate, a light emitting structure including a first conductive semiconductor layer, an active layer and a second conductive semiconductor layer, formed on the buffer layer, a first electrode formed on the first conductive semiconductor layer, and a second electrode formed on the second conductive semiconductor layer, wherein the substrate has a light transmitting property, and respective corners of the substrate are rounded so as to have a designated curvature. |
