Abstract
A light emitting diode array including apertures, a line printer head using the light emitting diode array, and a method of manufacturing the light emitting diode array. The light emitting diode array includes the apertures that are formed in a substrate and restrict tunnels of light emitted from a plurality of light emitting diodes. Also, a lens that refracts the light transmitted through the plurality of apertures is included.
