PURPOSE: A light emitting device is provided to form a concave part without an additional process by forming the concave part on a silicon base substrate in a process of forming a light extracting pattern. CONSTITUTION: A substrate(101) includes a first surface and a second surface. A light emitting structure(135) is formed on the first surface of the substrate and includes a first conductive semiconductor layer(110), an active layer(120), and a second conductive semiconductor layer(130). A first electrode(112) is formed on the first conductive semiconductor layer. A light transmission conductive layer(132) and a second electrode(134) are formed on a second conductive semiconductor layer. |
