Abstract: A display device includes a light emitting diode LED element having a horizontal length in an X-axis direction and a vertical length in a Y-axis direction, a driving element connected to the LED element, and a reflective functional layer positioned to overlap an upper portion or a lower portion of the LED element, wherein the reflective functional layer includes a central area overlapping the LED element, an outer area including a graduation smaller than the horizontal length or the vertical length of the LED element, and a peripheral area between the central area and the outer area. Accordingly, it is possible to reduce a contact defect of the light emitting diode and the driving element by checking a position where the light emitting diode is attached on a substrate and a degree of misalignment.

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.
