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