PURPOSE: An LED(Light Emitting Diode) and a method for manufacturing the same are provided to improve an optical output by emitting lights into a substrate instead of an upper clad layer and by forming a reflective film on an ohmic contact layer. CONSTITUTION: A first clad layer(13) made of N-type GaN is formed on a transparent substrate(11). An active layer(14) is formed on the first clad layer. A second clad layer(15) of P-type GaN is formed on the active layer. An ohmic contact layer(16) is formed on the second clad layer. A reflective film(17) is formed on the ohmic contact layer to reflect lights generated in the active layer. An electrode pad(18) is formed on a desired portion of the first clad layer. The reflective film(17) is made of Ag/Ni/Au or Ag/Pt/Au. |
