    Abstract: According to an aspect of the present disclosure, a display device includes a substrate in which a plurality of sub pixels is defined; a light emitting diode disposed on the substrate in each of the plurality of sub pixels; and a planarization layer which covers the light emitting diode and includes a first contact hole overlapping the light emitting diode. The first contact hole is formed to have a width which is narrowed from an upper portion of the first contact hole toward a lower portion of the first contact hole. Accordingly, the first contact hole is formed to have a step shape so that the exposure of the side surface part of the light emitting diode through the first contact hole and the disconnection of the pixel electrode may be minimized.

    Abstract: A touch display device can include a substrate including an active area and a non-active area, a transistor disposed on the substrate, a sub-pixel electrically connected to the transistor and including an organic light emitting diode, an encapsulation layer disposed on the organic light emitting diode, a planarization layer disposed on the encapsulation layer and including a lens unit, and a plurality of touch electrodes disposed between the encapsulation layer and the planarization layer. The plurality of touch electrodes can include an open area. Further, the lens unit can be disposed in the open area of the plurality of touch electrodes.
