    Abstract: According to one embodiment, a display device includes a display pixel allocated at a matrix state in a display area, an image-reading device which detects strength of capacitive coupling by a dielectric material coming close to or making contact with the display area, and a control portion which controls each transistor of the image-reading device. The image-reading device includes a detection electrode which forms capacitance between the detection electrode and the dielectric material, a pre-charge gate line, a coupling pulse line, a readout gate line, a pre-charge line and a readout line. These lines supply a signal which drives the image-reading device. The image-reading device further includes a pre-charge transistor, an amplification transistor, a readout transistor, a compensation transistor, and a power-source switching transistor.

    Abstract: According to an aspect, a display device includes scan lines, signal lines, a scan circuit, a signal output circuit, pixels each having a switching element and a pixel electrode, a common electrode, and a common electrode drive circuit. In a potential reset period to reset a potential of the pixel electrode and a common potential inversion period subsequent to the potential reset period, the scan circuit supplies, to the scan lines, a drive potential to drive the switching elements, and the signal output circuit supplies, to the signal lines, an intermediate potential between a potential corresponding to a maximum gradation value and a potential corresponding to a minimum gradation value. In the common potential inversion period, the common electrode drive circuit switches the common potential between a first common potential and a second common potential higher than the first common potential.
