Abstract: A display apparatus having a light-emitting device and a touch electrode is provided. An optical pattern may be disposed on the light-emitting device. A side of the optical pattern may be sloped. A surface of the optical pattern opposite to the light-emitting device may be covered by an intermediate insulating layer. The intermediate insulating layer may be harder than the optical pattern. The touch electrode may overlap the side of the optical pattern. Thus, in the display apparatus, the surface defect of the optical pattern in the forming process of the touch electrode may be prevented. Therefore, in the display apparatus, the frontal luminance and the image quality may be improved.

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.
