摘要:
A display apparatus includes: a plurality of pixel circuits; and a signal supply circuit which supplies any one of a potential of a video signal, an extinction potential for extinguishing light-emitting devices, and a high-level potential higher than the extinction potential, wherein each of the plurality of pixel circuits includes a storage capacitor which retains a voltage corresponding to the video signal, a drive transistor which supplies a current based on the voltage retained in the storage capacitor to the corresponding light-emitting device, a light-emitting device which emits light in accordance with the current supplied from the drive transistor, and a write transistor which writes the voltage corresponding to the video signal to the storage capacitor after the potentials supplied by the signal supply circuit in order of the high-level potential and the extinction potential are given to the gate terminal of the drive transistor.
