Abstract: A display device may include a substrate on which pixels are defined, each pixel including a plurality of sub-pixels; a step formation layer disposed on the substrate; an adhesive layer disposed on the step formation layer; and a plurality of light-emitting elements respectively disposed in the plurality of sub-pixels, and disposed on the adhesive layer. The adhesive layer may include: a plurality of first portions respectively overlapping the light-emitting elements, a plurality of non-adhering areas respectively disposed adjacent to the plurality of first portions; and a second portion other than the plurality of first portions and the plurality of non-adhering areas. Accordingly, a transfer process may be simplified, and a transfer process time may be reduced. A method for manufacturing the display device is also disclosed.

Abstract: A manufacturing method of a display device may include: transferring light emitting diodes onto a display panel using an alignment key on a wafer; determining a defective light emitting diode which is missed or misplaced from a transferring position; and transferring at least one light emitting diode for repairing the defective light emitting diode onto the display panel using a repair alignment key. The method can improve a repair process efficiency. In a display device, at least one light emitting diode of a pixel may be in a second electrode area of an electrode area, and each of other light emitting diodes of the pixel may be disposed in a first electrode area of an electrode area of the pixel but not in a second electrode area of the electrode area. Some corresponding light emitting diodes of two pixels may be separated by a distance different from a pixel distance.
