Display device and method of manufacturing the same

A method of manufacturing a display device, the method comprising:

• arranging a first alignment mark of a display panel and a second alignment mark of an optical member to overlap each other in a thickness direction such that a center of the first alignment mark is aligned with a center of the second alignment mark;
• and
• moving at least one of the display panel or the optical member based on a first distance from a first alignment reference pixel to the first alignment mark, wherein the first alignment reference pixel provides a specific viewpoint among a plurality of viewpoints, wherein the moving of at least one of the display panel or the optical member includes misaligning the center of the first alignment mark with the center of the second alignment mark by a second distance, after aligning the center of the first alignment mark with the center of the second alignment mark, wherein the center of the first alignment mark is not realigned with the center of the second alignment mark,
• wherein the second alignment mark is disposed on a plurality of lenses of the optical member,
• wherein the second alignment mark is disposed on a lens, among the plurality of lenses, overlapping the first alignment reference pixel.
