Display device and display device provided with sensor

A display device provided with a sensor, comprising:

• a pair of groups of electrodes for a touch sensor, one of the groups of electrodes extending in a single direction, the other group of electrodes being arranged to intersect the one group of electrodes;
• plural display pixels arranged in a matrix;
• plural gate lines extending along rows in which the plural display pixels are arranged;
• plural source lines extending along columns in which the plural display are arranged;
• 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 a pixel electrode and a common electrode;
• 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;
• and
• the source lines are also used as the one of groups of electrodes for the touch sensor.
