Abstract

A display device comprises gate lines extending in a first direction, drain lines extending in a second direction, common electrodes extending in the second direction, and a drive circuit. The common electrodes are configured to be partitioned over drain lines of pixels of a specific color and to be used also as touch panel scan electrodes. The drive circuit is configured so that write periods for driving the gate lines and touch sensing periods for driving the scan electrodes are alternately repeated in each frame period, signal polarity of drain lines for colors other than the specific color is inverted every frame, signal polarity of drain lines for the specific color is inverted at a cycle shorter than one frame, and the cycle of the signal polarity inversion of the drain lines for the specific color can be changed.
