PIXEL CIRCUIT, DRIVING METHOD THEREOF AND DISPLAY DEVICE

摘要

To provide a pixel circuit and the like capable of preventing contrast deterioration caused by leaked light emission at the time of reset actions. The pixel circuit includes: a light emitting element; a driving transistor which supplies an electric current to the light emitting element according to an applied voltage; a capacitor part which holds a voltage containing a threshold voltage and a data voltage of the driving transistor and applies the voltage to the driving transistor; and a switch part which makes the capacitor part hold the voltage containing the threshold voltage and the data voltage. The switch part includes a current detour transistor which makes the electric current supplied from the driving transistor detour to a reference voltage power supply line without going through the light emitting element.
