Abstract

A sensor layer includes: first sensing electrodes extending in a first direction; second sensing electrodes extending in a second direction; and first electrodes extending in the first direction. The first sensing electrodes includes first sub electrodes, and the first electrodes includes second sub electrodes. The first sub electrodes includes first patterns, and a first bridge pattern electrically connected to the first patterns. Two first sub electrodes are electrically connected to each other at one end via a first connection line. Two second sub electrodes overlapping with the two first sub electrodes are connected to each other at a second end via a second connection line. The second connection line and another adjacent second connection line are electrically connected to each other via a third connection line. The first connection line is electrically connected to a first pad, and the third connection line is electrically connected to a second pad.
