Abstract
Disclosed are a white light emitting diode and a method for manufacturing the white light emitting diode. The white light emitting diode comprises a conductive substrate with a light transmitting property having a surface divided into first and second areas; a first emitting unit including a first clad layer, a first active area, and a second clad layer at the first area of the conductive substrate; a second emitting unit including a third clad layer, a second active area emitting light with a wavelength to be combined with light emitted from the first active area into white light, and a fourth clad layer at the second area of the conductive substrate; and first, second and third electrodes, the first electrode connected to the second surface of the conductive substrate, the second electrode connected to the second clad layer, and the third electrode connected to the fourth clad layer.
