A method of producing an image display unit includes the steps 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 while keeping
the array of the display elements; 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 magnetically attracting
the selected display elements while keeping the specific intervals thereof, and
transferring the selected display elements onto a mounting board. The method may
further include the step of repeating the selective magnetization step and the
mounting step, to array all of the display elements at the specific intervals on
the mounting board. With this method, the handling of fine LED pellets can be improved.
