Claim:
A method of producing an image display unit, comprising: an element formation step of forming, on a wafer, a display element layer composed of display elements arrayed on a specific cycle and provided with a magnetic film, and separating the display element layer into the individual display elements with magnetic film portions individually separated from the magnetic film while keeping the array of the display elements; a selective magnetization step of selecting, of all of the display elements, those located discretely at specific intervals of a value equivalent to an integer-fold of the specific cycle, and magnetizing the magnetic film portions provided on the selected display elements in such a manner that the magnetic film portions provided on the selected display units are magnetically distinguishable from the magnetic film portions provided on the non-selected display elements; and a mounting step of magnetically attracting the selected display elements while keeping the specific intervals thereof, and transferring the selected display elements onto a mounting board.
