Abstract:
According to one embodiment, a display device includes plural display pixels arranged in a matrix, plural gate lines, plural source lines and a control circuit which controls by applying intermittent driving and a column-inversion drive scheme, an operation in which drive signals are supplied to the gate lines and the source lines, and an image signal is supplied to the display pixels and held thereby, wherein the display pixels each include a liquid crystal in which alignment of liquid crystal molecules is changed by a voltage between pixel electrodes and a common electrode, and the control circuit applies in a signal stop period in the intermittent driving, a voltage corresponding to a gradation higher than or equal to white gradation to the source lines in a case where a display mode of the liquid crystal is a normally-black mode.
