摘要：
Disclosed herein are a patterned substrate for a light emitting diode and a light emitting diode employing the patterned substrate. The substrate has top and bottom surfaces. Protrusion patterns are arranged on the top surface of the substrate. Furthermore, recessed regions surround the protrusion patterns. The recessed regions have irregular bottoms. Thus, the protrusion patterns and the recessed regions can prevent light emitted from a light emitting diode from being lost due to the total reflection to thereby improve light extraction efficiency.
