摘要
According to one embodiment, a display device equipped with a touch detection function includes scanning lines, and series-connected unit register circuits, wherein a touch detection operation is performed in a scan stop period, each of the unit register circuits is composed of single-channel transistors, holds and outputs a scanning signal when a voltage leak of a held signal is equal to or lower than a predetermined value, a dummy unit register circuit is provided between a previous unit register circuit which drives a last scanning line before start of the scan stop period and a subsequent unit register circuit which drives a first scanning line after end of the scan stop period, and the dummy unit register circuit continues outputting the scanning signal to the subsequent unit register circuit during the scan stop period.
