Title:
MULTI-LUMINOUS ELEMENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2011/115414
Kind Code:
A3
Abstract:
The present invention relates to a multi-luminous element and a method for manufacturing the same. The present invention provides the multi-luminous element comprising: a buffer layer disposed on a substrate; a first type semiconductor layer disposed on the buffer layer; a first active layer which is disposed on the first type semiconductor layer and is patterned to expose a part of the first type semiconductor layer; a second active layer disposed on the first type semiconductor layer which is exposed by the first active layer; and a second type semiconductor layer disposed on the first active layer and the second active layer, the first and second active layers being repeatedly disposed in the horizontal direction, and the method for manufacturing the same. The multi-luminous element according to the present invention reduces loss of light emitting efficiency and can generate multi-wavelength light by repeatedly disposing the first and second active layers in the horizontal direction.
