description A fingerprint sensor is provided and includes substrate; sensor electrodes on substrate; first switches coupled to sensor electrodes; organic layer covering sensor electrodes; control line drive circuit in first direction; signal line drive circuit in second direction orthogonal to first direction; signal lines coupled to first switches; control lines coupling first switches to control line drive circuit; sensor drive electrode surrounding sensor electrodes; second switches between signal line drive circuit and signal lines; and first number of third switches between signal line drive circuit and first number of second switches, wherein distance of sensor drive electrode from surface of substrate is larger than distance of sensor electrodes from surface of substrate, and wherein first number is less than number of all second switches.
