Patent ID: 7808008

Claim:
A display device comprising: a pixel including: a light-emitting element, a first switching device configured to sample a potential of a video signal, a driving transistor, a second switching device configured to control connection between a gate and a drain of the driving transistor, a third switching device configured to control application of an initial potential for correction to the gate of the driving transistor, a fourth switching device configured to select whether the drain of the driving transistor is set to be in a floating state, and a capacitor for holding a voltage between the gate and a source of the driving transistor; and a driver circuit configured to apply the initial potential for correction having different value depending on a potential of the video signal to the pixel, wherein the driving transistor is configured to supply a current to the light-emitting element when a potential obtained by subtracting the voltage held in the capacitor from a potential of the video signal is applied to the gate of the driving transistor.
