1. A drive circuit which outputs an output signal to an output terminal, comprising:

  • a drive transistor configured to output a gradation current to said output terminal;

    a single differential amplifier;

    a resistance element connected with said drive transistor; and

    a plurality of switches, wherein said plurality of switches are controlled such that a precharge voltage is outputted from said differential amplifier to said output terminal in a first period while blocking off an output from said drive transistor and such that a gradation current is outputted from said drive transistor to said output terminal in a second period after said first period.
