Classification: CPC H | IPC H

Claim 17:
18. A manufacturing method of a display device, comprising:
transferring a plurality of light emitting elements grown on a growth substrate onto a first film to be spaced from one another by a first distance;
expanding the first film by using an expanding device to space each of the plurality of light emitting elements on the first film from adjacent light emitting elements by a second distance larger than the first distance;
retransferring the light emitting elements that are spaced from one another by the second distance on the first film to a second film;
determining positions of the light emitting elements on the second film by irradiating a guide laser beam;
removing an ineffective light source from among the light emitting elements on the second film, and binning the light emitting elements;
forming a plurality of pixels on a substrate, each of the pixels comprising one or more of transistors, a first electrode electrically connected to a transistor from among the one or more transistors, and a bonding electrode on the first electrode;
transferring each of the light emitting elements on the second film to a corresponding bonding electrode of a corresponding pixel from among the plurality of pixels by irradiating a laser beam by using a laser shot;
bonding each of the transferred light emitting elements to the corresponding bonding electrode of the corresponding pixel; and
forming a second electrode on each of the transferred light emitting elements.
