Abstract: According to an aspect, a display device with a sensor includes: a substrate including a display region and a peripheral region on a periphery of the display region; detection electrodes arranged in a row-column configuration in the display region; and detection lines coupled to the respective detection electrodes. A shape of the substrate in a plan view includes a curve of a curved portion. The detection electrodes include a first electrode and a second electrode having a shape different from that of the first electrode in a plan view. The second electrode is juxtaposed with the curved portion. The detection lines each include a first line coupled to the first electrode and a second line coupled to the second electrode. The second line passes from the display region across the peripheral region and extends to a position overlapping with the second electrode in a plan view.
