1. An input sensor comprising:
a first electrode extending along a first direction and configured to transmit a first signal;
a second electrode configured to transmit a second signal different from the first signal, and including a plurality of first sensor patterns arranged along a second direction intersecting the first direction and a first intersecting wire and connecting the first sensor patterns to each other;
a third electrode configured to transmit a third signal different from the first signal, and including a plurality of second sensor patterns alternately arranged with the first sensor patterns along the second direction and a second intersecting wire and connecting the second sensor patterns to each other; and
a sensor driving circuit including an output part configured to output a signal obtained by subtracting the third signal from the second signal,
wherein the first intersecting wire and the second intersecting wire are on a same layer as the first sensor patterns and the second sensor patterns,
wherein the second electrode further includes a bridge on a different layer from the first sensor patterns,
wherein the first intersecting wire is connected to the first sensor patterns via the bridge.
