摘要
A display device with a touch sensor according to the present invention includes an active matrix substrate 4A and a transparent counter electrode 7. On a first surface of the active matrix substrate, multiple pixel electrodes are arranged in matrix. The transparent counter electrode is opposed to the first surface of the active matrix substrate. The display device further includes a first circuit, a second circuit and a switching circuit. The first circuit supplies a voltage or a current to the transparent counter electrode for display purposes. The second circuit detects currents flowing from a number of points on the transparent counter electrode. And the switching circuit selectively connects electrically one of the first and second circuits to the transparent counter electrode.
