Abstract: An input sensing unit may include sensing electrodes and auxiliary electrodes. The sensing electrodes may be disposed in an input-sensing area of the input sensing unit. The auxiliary electrodes may be disposed in a supplementary area and may sense damage occurring in an auxiliary area of the input sensing unit. The supplementary area may be adjacent to the input-sensing area. The auxiliary area may be part of the supplementary area.
