ABSTRACT OF THE DISCLOSURE In an LED array, an opaque layer is provided on a semiconductor body having PN junctions. Through holes, having a relatively small diameter, are formed in the opaque layer on the PN junctions. Light which is generated at the PN junctions is emitted only through the holes in the form of photobeams. The LED array can be used in an electronic printer for photography without a self-focus lens array. -17-
