Apparatus and method for manufacturing display device

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.
