Abstract

There is provided a touch panel, including: a substrate including a touch detection area and a fingerprint recognition area; plural touch detection units in the touch detection area, each touch detection unit including a touch detection electrode; plural fingerprint recognition units in the fingerprint recognition area, each fingerprint recognition unit including a fingerprint recognition electrode, and the fingerprint recognition electrode and the touch detection electrode being in a same layer; a signal wiring layer on a same side of the substrate as the touch detection electrode and the fingerprint recognition electrode and including plural first signal transmission lines and plural second signal transmission lines. The touch detection electrode is electrically coupled to and transmits a touch detection signal through a corresponding first signal transmission line, and the fingerprint recognition electrode is electrically coupled to and transmits a fingerprint recognition signal through a corresponding second signal transmission line.
