Abstract: A touch sensor includes a substrate, an insulating layer, a sensor, and sensing lines. The substrate includes: a sensing region, and a peripheral region at a periphery of the sensing region. The insulating layer is on the substrate. The insulating layer includes contact holes. The sensor is on the substrate and overlaps the sensing region. The sensing lines are on the substrate and overlap the peripheral region. The sensing lines are connected to the sensor. Each of the sensing lines is formed as a multilayer structure. The multilayer structure includes a first electrically conductive layer on the substrate, and a second electrically conductive layer connected to the first electrically conductive layer via a contact hole among the contact holes. Widths of the sensing lines are different from one another.

Abstract: 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.
