1. A method for manufacturing a naked-eye 3D device, comprising:
forming a display module including a plurality of pixel islands;
forming a spacer layer on the display module; and
forming a micro-lens array on the spacer layer, wherein the spacer layer is formed to have a thickness such that the plurality of pixel islands are located at a focal plane of the micro-lens array;
wherein the method further includes:
forming an alignment mark between the spacer layer and the display module, wherein the alignment mark is used for, when forming the micro-lens array, aligning each micro-lens in the micro-lens array with one of the plurality of pixel islands.
