Abstract
To provide a touch panel in which a decrease in display quality is suppressed. The touch panel includes a touch sensor and a display element. The touch sensor includes a transistor and a sensor element. The transistor is electrically connected to the sensor element. The sensor element includes a pair of electrodes and a dielectric layer. The dielectric layer is positioned between the pair of electrodes. One of the pair of electrodes is an island-shaped electrode. The display element can display an image toward the touch sensor side. The island-shaped electrode does not overlap with a display region of the display element.
