ABSTRACT:
A light-emitting diode array comprising a conductive layer formed on a substrate, pluralities of separate light-emitting portions formed on the conductive layer, a first groove formed in the conductive layer to divide the light-emitting portions to blocks, first electrodes each formed on at least part of an upper surface of each light-emitting portion, one second electrode formed directly on the conductive layer in each block, common switching wirings separately connected to the first electrodes, first bonding pads each connected to each common wiring, first bonding pads each connected to each common wiring, and second bonding pads each connected to each second electrode, n light-emitting portions (n is an even number) being arranged transversely in each block, and second grooves being formed in the conductive layer between adjacent light-emitting portions such that the second grooves are arranged short and long alternately, with the nearest one to the first groove being short.
