A structure of a light emitting diode (LED) having high brightness is disclosed. This LED includes a substrate on a first electrode, a first cladding layer of a first conductivity type on the substrate, an active layer on the first cladding layer, a second cladding layer of a second conductivity type on the active layer, a window layer of the second conductivity type on the second cladding layer, wherein the electrical resistivity of the window layer is less than that of the second cladding layer, a contact layer of the second conductivity type on the window layer for providing ohmic contact, and a conductive transparent oxide layer on the contact layer, wherein the electrical resistivity of the conductive transparent oxide layer is less than that of the window layer and the contact layer.
