Abstract
A display device which can achieve compatibility between the simplicity of the configuration or control of electronic equipment and the maintaining of its high operability includes: a display panel and a touch panel arranged on a front surface side of the display panel as viewed from a viewer. The touch panel includes one transparent substrate and a conductive pattern disposed on the substrate. A plurality of detection areas in each of which a touch position can be detected are provided in the touch panel. A non-detection area in which the touch position is not detected is provided between two detection areas next to each other.
