Abstract
A touch-sensored display deviceaccording to the present invention includes: a counter substratedisposed on a viewer side of an active matrix substratevia a display medium layer, the counter substratehaving a counter electrodewhich opposes pixel electrodes; a display panel driving circuitfor supplying to the counter electrodea common voltage which undergoes periodic inversion in polarity; a transparent conductive filmfor position detection placed so as to oppose the counter electrodevia the counter substrate; a strobe signal generation circuitfor generating a strobe signal which is in synchronization with a polarity inversion period of the common voltage, and a noise-cut current signal generation circuitfor generating a noise-cut current signal which is obtained by eliminating based on the strobe signal a predetermined portion from a current flowing from a terminal connected to the transparent conductive filmfor position detection.
