Abstract: A detection device and a display device include first electrodes, second electrodes, a detector, and a coupling circuit. The first electrodes are disposed side by side in a first direction and a second direction intersecting the first direction. The second electrodes are disposed on the side facing the first electrodes and extend in the second direction. The detector receives a first detection signal output from the second electrodes based on changes in capacitance between the first electrodes and the second electrodes or a second detection signal output from the first electrodes based on changes in capacitance in the first electrodes.
