1. A display device which displays image information based on display data comprising at least:

  • a display panel which has a plurality of signal lines and a plurality of scanning lines situated in directions to mutually intersect and a plurality of display pixels containing current control type light emitting devices positioned near each intersecting point of those plurality of signal lines and plurality of scanning lines;

    a scan driver circuit which applies a scanning signal to each of the plurality of scanning lines and sets the display pixels connected to the scanning lines in a selective state;

    a signal driver circuit which generates gradation current based on the display data luminosity gradation component and supplies to the display pixels set in the selective state by the scan driver circuit via each of the signal lines;

    a precharge circuit which applies a precharge voltage to each of the plurality of signal lines and sets a capacity component attached to each of the signal lines in a predetermined charged state; and

    an operation control circuit which controls setting of the light emitting devices in a non-light emitting state when the capacity component is set in a predetermined charged state by the precharge circuit.
