Abstract
A fingerprint sensor comprises a read-out line disposed on a substrate and extending in a first direction, a first sensor transistor controlling a sensing current based on a voltage of a sensor node, a second sensor transistor supplying a reset voltage to the sensor node based on a reset signal, a third sensor transistor electrically connected a first electrode of the first sensor transistor and the read-out line based on a gate signal, and a fourth sensor transistor comprising a gate electrode connected to a bias voltage line, a first electrode connected to the bias voltage line, and a second electrode connected to the sensor node.
