Non-rigid device and display device
A device with a flexible region that is manipulable in a second standard direction substantially perpendicular to a rotational axis extending in a first standard direction includes a flexible touch sensing panel. The flexible touch sensing panel includes first touch sensing electrodes and a first bridge. The first bridge is on a layer substantially different from a layer on which the first touch sensing electrodes are located and the first bridge connects two first touch sensing electrodes adjacent to each other.
