Abstract

A touch display device includes a display unit including pixels disposed in an active area, an encapsulation unit disposed on the display unit, and a touch-fingerprint fusion sensor unit having a touch sensor function and a fingerprint sensor function in the active area on the encapsulation unit. The touch-fingerprint fusion sensor unit includes first fingerprint sensor electrodes disposed in a fingerprint sensor area on the encapsulation unit, a first touch insulating layer disposed on the first fingerprint sensor electrodes, second fingerprint sensor electrodes disposed in the fingerprint sensor area on the first touch insulating layer, a second touch insulating layer disposed on the second fingerprint sensor electrodes, and a plurality of first and second touch electrodes disposed on the second touch insulating layer. The first fingerprint sensor electrodes, the second fingerprint sensor electrodes, and the first and second touch electrodes overlap the non-emissive area.
