Patent ID: 7504772

Claim:
A light-emitting diode array comprising a conductive layer formed on a substrate, separate light-emitting portions formed on said conductive layer, a first electrode formed on at least part of an upper surface of each light-emitting portion, and a second electrode formed on said conductive layer adjacent to said light-emitting portions; said first electrode comprising a common switching electrode matrix; said second electrode comprising a common electrode divided such that one second electrode exists in every light-emitting portion separate from other light-emitting portions; and at least one bonding pad of bonding pads extending to said first electrode comprising a common switching electrode matrix and said second electrode comprising a common electrode divided being formed on a bonding portion formed on said conductive layer on epitaxial layers separated from each other by a first mesa-etched groove removing part of said epitaxial layers, whereby said bonding pads are separate from each other, wherein said first electrode comprising a common switching electrode matrix and said second electrode comprising a common electrode divided as such for each of said light-emitting portions are formed respectively on the bottom surface of a mesa-etched groove different from the first mesa-etched groove formed by removing said conductive layer, said first electrode comprising a common switching electrode matrix being formed on an insulating layer formed in said mesa-etched groove and said second electrode comprising a common electrode divided as such being formed on a conductive layer.
