Abstract: In a display apparatus provided with an electrophoresis layer, such a display apparatus as to improve the response performance of a touch detection is provided. A driving unit included in a display apparatus alternately repeats a display driving process for supplying a first driving signal to a driving electrode disposed in a selected partial display region and a detection driving process for supplying a second driving signal to a driving electrode disposed in another selected partial display region while successively cyclically changing the partial display region and successively cyclically changing another partial detection region. Moreover, in the detection driving process, a touch detection unit included in the display apparatus detects an input position at another selected partial detection region based on an electrostatic capacitance of the driving electrode disposed at another selected detection region.
