<p>A display with a touch sensor comprises an active matrix substrate (4A) having pixel electrodes arranged in a matrix on a first surface and a transparent counter electrode (7) facing the first surface of the active matrix substrate. This display also comprises a first circuit for supplying display voltage or current to the transparent counter electrode, a second circuit for sensing current flowing from a plurality of points of the transparent counter electrodes, and a switching circuit for electrically connecting either of the first circuit and the second circuit with the transparent counter electrode.</p> |
