Abstract
An organic light emitting display device having a touch panel function comprises at least one organic light emitting diode and an encapsulating thin film for encapsulating the organic light emitting diode; and an external input device formed on the display panel for generating an electric signal in response to a touch operation applied from the exterior thereof. The external input device includes an upper substrate and a spacing member. The external input device has a third electrode formed on the display panel and a fourth electrode formed on the upper substrate to intersect the third electrode. The spacing member forms a predetermined spacing between the third electrode and the fourth electrode.
