Patent abstract
To prevent image retention, the pixel circuit includes: a light emitting element; a driving transistor which supplies an electric current according to an applied voltage to the light emitting element; a capacitor part which holds the voltage containing a threshold voltage and a data voltage of the driving transistor; and a switch part which has the voltage containing the threshold voltage and the data voltage held to the capacitor part and applies the voltage to the driving transistor. Further, the switch part has a function which applies a constant voltage to the driving transistor before having the voltage containing the threshold voltage and the data voltage held to the capacitor part.
