A display device includes a display panel and an input sensing part disposed on the display panel. The input sensing part includes first sensing electrodes extending in a first direction and arranged in a second direction crossing the first direction, first lines connected to the first sensing electrodes, second sensing electrodes extending in the second direction and arranged in the first direction, and second lines connected to the second sensing electrodes. The second lines include second-first lines defined as j-th to k-th second lines, and the first lines are connected to the second-first lines.
