Abstract: Provided is an organic light emitting display device. The organic light emitting display device includes a lower substrate including sub-pixels, a display area, a non-display area, and an exposed area; a lower touch pad unit in the non-display area and adjacent to the exposed area on the lower substrate; an upper substrate disposed opposite to the remaining area excluding the exposed area of the lower substrate; an upper touch pad unit on the upper substrate so as to correspond to the lower touch pad unit; a first connection electrode in direct contact with the lower touch pad unit; a second connection electrode opposite to the first connection electrode and in direct contact with the upper touch pad unit; and a self-assembly contact member disposed between the first connection electrode and the second connection electrode so as to electrically connect the first connection electrode and the second connection electrode.

Abstract: Embodiments of the disclosure relate to touch display devices. Display pads and touch pads may be arranged on the same side of a display panel by removing a portion of a second substrate to thereby expose the touch pads to the outside after attaching the second substrate on which the touch pads are arranged to a first substrate on which the display pads are arranged.
Since the touch pads are positioned higher than the display pads in the area that does not overlap the display pads, bonding between the pads and the printed circuit may be easy to perform. Since the number of pads that may be arranged increases, it is possible to easily implement a large-area, high resolution touch display device.-
