Abstract
A display device includes image lines, a signal source, position detecting lines, and a switch circuit. The image lines are disposed in a display area in which an image is displayed. The signal source is disposed outside the display area and connected to the image lines. The signal source is configured to supply image signals and position detecting signals to the image lines with time-division. The position detecting lines are disposed in the display area. The switch circuit is disposed on an opposite side from the signal source relative to the display area outside the display area and connected to the image lines and the position detecting lines. The switch circuit is configured to electrically connect the image lines and the position detecting lines in synchronization with feedings of the position detecting signals to the image lines by the signal source.
