Abstract
A method for driving a touch panel-mounted electrophoretic display device includes: connecting a first control line or a second control line and a first electrode of the device with a switching circuit based on output from a memory circuit, and setting the electric potentials of the first and second control lines to first and second potentials, during an inputting period when positional information is input to the touch panel; and inputting an image signal including a touch panel signal for displaying the trajectory of the positional information input to the touch panel to the memory circuit of the selected pixel through the data lines and a pixel switching element by selecting the pixel connected to the corresponding scanning line by simultaneously supplying a scanning signal to the scanning lines while the potential of the second electrode is set to the first electric potential.
