Display apparatus and electronic instrument

An electronic instrument comprising:

• 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 a light-emitting device, a reference potential lower than the extinction potential and a high-level potential higher than the extinction potential,
• wherein,
• the pixel circuits are driven in an extinction period, a threshold correction period and a light-emission period;
• and
• 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 connected to receive each of the potential of a video signal, the extinction potential for extinguishing light-emitting devices, the reference potential, and the high-level potential higher than the extinction potential, and which writes the voltage corresponding to the video signal to the storage capacitor during a current horizontal scan period after supplying the high-level potential and the extinction potential during the extinction period and the reference potential during the threshold correction period, in that order to a gate of the drive transistor.
