Abstract
Provided is a display device including a driver circuit for controlling supply of charges to an array of cells capable of storing the charges. In the driver circuit, a preceding electrically connecting part (SW221) controlled by a clock signal (CLK1) electrically connects an output signal line of a first circuit (211) having a positive polarity which is a potential higher than a reference potential and an output signal line of a second circuit (212) having a negative polarity which is a potential lower than the reference potential. After a predetermined time period has elapsed, a subsequent electrically connecting part (SW222) controlled by a clock signal (CLK2) electrically connects an output signal line of a third circuit (213) having the positive polarity and an output signal line of a fourth circuit (214) having the negative polarity.
