In a driver circuit which controls the supply of charge to cells each of which can store a charge, the EMI (Electro Magnetic Interference) which occurs at the time of performing the charge sharing driving can be reduced. A preceding conduction means (SW13) which is controlled in response to a clock signal (CLK1) makes an output signal line corresponding to a first circuit which has positive polarity of a potential higher than a reference potential and an output signal line corresponding to a second circuit which has negative polarity of a potential lower than the reference potential electrically conductive with each other. After a lapse of a predetermined time, a succeeding conduction means (SW23) which is controlled in response to a clock signal (CLK2) makes an output signal line corresponding to a third circuit which has the positive polarity and an output signal line corresponding to a fourth circuit which has the negative polarity electrically conductive with each other.
