Abstract
A light-emitting diode array comprising a conductive layer formed on a substrate, separate light-emitting portions formed on the 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 the conductive layer adjacent to the light-emitting portions; the first electrode comprising a common switching electrode matrix; the second electrode comprising a common electrode divided such that one second electrode exists in every block; and at least one of bonding pads extending to the first common electrode and the second common electrode being formed on a bonding portion formed on the conductive layer like an island, whereby the bonding pads are separate from each other.
