A display apparatus, a driving method thereof and an electronic device are provided to correct mobility of a drive transistor by using a portion of sampling period. A pixel circuit(2) includes a sampling transistor(Tr1), a drive transistor(Trd), a first switching transistor(Tr2), a second switching transistor(Tr3), a third switching transistor(Tr4), a pixel capacitance(Cs), and a light emitting element(EL). The sampling transistor becomes conductive in accordance with a control signal supplied from a scanning line(WS) during a predetermined sampling period, and samples to the pixel capacitance a signal potential of a video signal supplied from a signal line(SL). The pixel capacitance applies an input voltage(Vgs) to a gate(G) of the drive transistor in accordance with the signal potential of the video signal that has been sampled. The drive transistor supplies to the light emitting element an output current corresponding to the input voltage. The light emitting element emits light at a brightness corresponding to the signal potential of the video signal by way of the output current that is supplied from the drive transistor during a predetermined light emitting period.
