Claim 19:
20. A method of manufacturing a display device, the method comprising:
growing a plurality of light-emitting elements on a base substrate;
attaching a polymer film comprising porogen on the plurality of light-emitting elements;
forming a polymer layer, which surrounds first end portions of the plurality of light-emitting elements, by heat-treating the base substrate to melt the polymer film;
separating the plurality of light-emitting elements and mixing the plurality of light-emitting elements in light-emitting element ink comprising a conductive polymer;
preparing a substrate comprising a first electrode and a bank;
forming a reflective material layer on the first electrode and the bank;
applying the light-emitting element ink on the reflective material layer;
aligning a conductive polymer layer and the plurality of light-emitting elements on the reflective material layer by drying the light-emitting element ink;
etching away the polymer layer from the plurality of light-emitting elements, and forming a reflective electrode by etching the reflective material layer;
forming an insulating layer on the conductive polymer layer and the reflective electrode; and
forming a second electrode on the plurality of light-emitting elements.
