Abstract
A touch-fingerprint complex sensor is provided for detecting a touch and a fingerprint of a user, using a touch pad including a touch region and a fingerprint recognizing region. The touch-fingerprint complex sensor includes a plurality of first electrodes disposed on a substrate, and arranged in parallel in a first direction, a plurality of second electrodes disposed on the substrate, and arranged in parallel in a second direction crossing the first direction, and an insulating layer disposed between the plurality of first electrodes and the plurality of second electrodes. A cross-sectional distance between the plurality of first electrodes and the plurality of second electrodes at intersections of the plurality of first electrodes and the plurality of second electrodes in the touch region excluding the fingerprint recognizing region is greater than that at intersections of the plurality of first electrodes and the plurality of second electrodes in the fingerprint recognizing region.
