1. A drive method for an EL display panel, the EL display panel comprising:

  • EL elements arranged in a matrix;

    driver transistors which supply current to be passed through the EL elements;

    first switching elements placed in current paths of the EL elements;

    a gate driver circuit which turns on and off the first switching elements for control; and

    a source driver circuit which supplies programming current to the driver transistors, wherein the driver transistors are p-channel transistors, unit transistors which generate the programming current in the source driver circuit are n-channel transistors, and the gate driver circuit turns off the first switching elements at least two or more times during one frame period or one field period.
