Title:
LIGHT EMITTING DIODE HAVING ELECTRODE PADS
Document Type and Number:
WIPO Patent Application WO/2011/074768
Kind Code:
A1
Abstract:
Disclosed is a light emitting diode. The light emitting diode includes: a substrate, a first conductive type semiconductor layer on the substrate, a second conductive type semiconductor layer on the first conductive type semiconductor layer, an active layer interposed between the first and second conductive type semiconductor layers, a first electrode pad electrically connected to the first conductive type semiconductor layer, a second electrode pad on the first conductive type semiconductor layer, and an insulation layer interposed between the first conductive type semiconductor layer and the second electrode pad and electrically insulating the second electrode pad from the first conductive type semiconductor layer. The second electrode pad is formed on the first conductive type semiconductor layer, thereby preventing current crowding and optical loss caused by electrode pads.
