Abstract
The present invention provides an optical element array that enables lens mounting at low cost and high precision, a display device enabling stereoscopic display using the optical element array, and a method of manufacturing the display device. A lens sheet of the present invention is configured by a plurality of unit lenses and a non-periodic flat part, the non-periodic flat part functioning as a lens reference mark for positioning. A display device is configured using the lens sheet such that the non-periodic flat part of the lens sheet overlaps a positioning mark of a display panel. Since the non-periodic flat part serving as the lens reference mark is arranged on the positioning mark, observation shift of the positioning mark due to lens effect in time of alignment does not occur, and high precision alignment is realized.
