More Information
Summary: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.
