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.
