A fingerprint sensor includes: a plurality of sensing electrodes provided on one surface of a base substrate, the plurality of sensing electrodes being arranged in a matrix form; and a ground electrode provided on the other surface of the base substrate. The ground electrode includes: a plurality of first lines extending in one direction, the plurality of first lines being parallel to one another; and a plurality of second lines extending in a direction intersecting the first lines, the plurality of second lines being parallel to one another. In a plan view, the first lines and the second lines are provided between adjacent sensing electrodes.

Fingerprint sensor, touch sensor having fingerprint sensor, and display device having touch sensor

A touch sensing apparatus including: a touch panel including a first electrode and a second electrode; a driver configured to apply a driving signal to the first electrode; a touch sensor configured to receive a signal transferred depending on the driving signal from the second electrode, and to convert and output the signal as a sensing signal; and a touch controller configured to detect the sensing signal. The touch panel further includes a third electrode and a fourth electrode which transfer noise signals having different magnitudes to the touch sensor, and the touch sensor outputs the sensing signal by using a difference in the noise signals and the signal.
