Claim Text:
1. A display device, comprising: a first substrate; a second substrate having detection electrodes of a touch panel; a plurality of pixels arrayed in a matrix, each having a pixel electrode and a counter electrode divided into a plurality of blocks; and a driver circuit that applies a counter voltage, a scanning voltage, a video voltage and a touch panel scanning voltage, wherein the divided counter electrodes of the respective blocks are commonly provided on the respective pixels, wherein the divided counter electrodes of the respective blocks are configured to work as scanning electrodes of the touch panel, wherein the driver circuit applies the touch panel scanning voltage to the divided counter electrodes at a time point which is after a delay period from a rising time point of a horizontal synchronizing signal, wherein the horizontal synchronizing signal has a constant frequency, wherein the delay period is different for different horizontal synchronizing signal according as a number of a predetermined delay time.
