Abstract: A display device comprises counter electrodes configured to be used as common electrodes for displaying and scan electrodes for touch sensing, a first scan circuit which scans gate lines, and a second scan circuit which scans the counter electrodes. In the display device, one frame period includes a write period for continuously scanning one screen and a touch sensing period existing between the write period and a write period in the next frame. The second scan circuit includes a shift register unit and a switch unit. The switch unit includes a seventh thin-film transistor which outputs a DC drive signal to an output node and an eighth thin-film transistor which outputs an AC drive signal to the output node. A second control signal for fixing the voltage of a third retention node to which the gate electrode of the seventh thin-film transistor is connected is inputted in the write period.

Abstract: Even when a light shielding film is provided between a transistor and a substrate, a threshold voltage of the transistor can be prevented or suppressed from being shifted. A display device includes light shielding films provided between a substrate and a semiconductor layer of a transistor including a gate electrode and the semiconductor layer. The semiconductor layer includes a source region and a drain region. Both of the light shielding films overlap the semiconductor layer when seen in a plan view, and are spaced apart from each other in a direction.

Abstract: The presence or absence of touch is detected according to a difference of a capacitance caused by the presence or absence of a material that blocks the electric field formed between the detection electrode and the common electrode. The common electrode includes a plurality of divided electrode portions that is extended in a lateral direction and aligned with each other in a longitudinal direction. Each of the plurality of common lines is electrically connected to at least one of the divided electrode portions. The plurality of common lines is arranged in an area next to the common electrode in the lateral direction of the common electrode, arranged next to each other in a width direction orthogonal to a length thereof, is different in width from each other, and the width of the common lines is wider as the length is longer.
