Abstract
A display device includes a display panel having a plurality of signal lines and scanning lines with a plurality of display pixels containing current control type light emitting devices; a scan driver circuit which applies a scanning signal to each of the 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 a display data luminosity gradation component and supplies to the display pixels set in the selective state; a precharge circuit which applies a precharge voltage to each signal line and sets a capacity component attached to each of the scanning 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.
