Abstract
According to one embodiment, a display device includes a first substrate, a second substrate opposed to the first substrate, detection electrodes provided to surround a display area where an image is displayed, and a common electrode provided over an entire surface of the display area. The common electrode includes a first lead wiring line that extends to a peripheral area around the display area, along a boundary part between a first detection electrode, which is one of the detection electrodes, and a second detection electrode adjacent to the first detection electrode. A capacitance formed between the first lead wiring line and the first detection electrode is substantially equal to a capacitance formed between the first lead wiring line and the second detection electrode.
