Abstract: A fingerprint sensor includes: sensor pixels, each including a first transistor which controls a sensing signal to be outputted to a corresponding one of output lines; power lines disposed on a vertical line basis and each electrically connected to sensor pixels disposed on a corresponding vertical line; and a power supply unit which supplies reference voltages to the power lines. The power supply unit supplies the reference voltages, which is adjusted on the vertical line basis, to the power lines.
