Abstract:
A light-emitting diode array having a plurality of light-emitting regions arranged in a row, and having oblong individual electrodes that have short sides and long sides thereof arranged respectively parallel to and perpendicular to a direction in which the light-emitting regions are arranged and that are bonded at a second stage of a ball bonding process, connected individually by way of wiring patterns to the light-emitting regions, arranged in at least two rows along the direction in which the light-emitting regions are arranged,wherein a protective film is laid on surfaces of the wiring patterns and without being laid upon the individual electrodes, part of the protective film lies on gaps between the rows of electrodes arranged along the direction in which the light-emitting regions are arranged, and part of the protective film lies partially on gaps between the individual electrodes arranged in an identical row, the row arranged farthest from the light-emitting region and having no wiring patterns between the individual electrodes.
