Abstract: According to one embodiment, a display device includes a display panel, switching elements, a power supply, a controller and a noise suppression circuit. The display panel displays an image. The switching elements supply a pixel signal to the display panel. The power supply supplies a power source voltage to the switching elements. The controller switches between a display period during which the display panel displays an image and a non-display period during which the display panel does not display an image. The noise suppression circuit preliminarily reduces a potential difference between the switching elements and the power supply when the controller switches between the display period and the non-display period.

Abstract: According to one embodiment, a display device includes a display and a driver. The display displays an image. The driver supplies a drive signal to the display. The driver determines, if power to drive the driver is supplied from power sources, whether a sequence of supplying the power is a predetermined sequence. A status of the driver remains as a status in which various commands are unacceptable in the case being determined that the sequence of supplying the power is not the predetermined sequence. The status of the driver is shifted to a status in which the various commands supplied to the driver are acceptable in the case being determined that the sequence of supplying the power is the predetermined sequence.
