Abstract
A fingerprint sensor includes: a gate line on a substrate and configured to supply a gate signal; a reset voltage line configured to supply a reset voltage; an initialization voltage line configured to supply an initialization voltage; a read-out line on the gate line and configured to supply a sensing signal; a light receiving element on the read-out line; a first sensor transistor configured to supply a sensing current based on a voltage of a sensor node, which is a first electrode of the light receiving element; a second sensor transistor comprising a second-first sensor transistor and a second-second sensor transistor connected in series between the reset voltage line and a gate electrode of the first sensor transistor; and a third sensor transistor comprising a third-first sensor transistor and a third-second sensor transistor connected in series between the read-out line and a first electrode of the first sensor transistor.
