The invention relates to an electro-optical device, a power supply method for an electro-optical device, and an electronic apparatus. A pixel circuit (110) includes a transistor, a light-emitting element, and a voltage limiter circuit. The transistor and the light-emitting element are connected in series between power supplies. The transistor allows an electric current that is dependent on a voltage between its gate and source to flow through the light-emitting element. The light-emitting element emits light at a luminance that is dependent on an electric current that flows between two terminals. The voltage limiter circuit performs voltage limiting in such a way as to ensure that a voltage between the drain of the transistor and the source thereof does not exceed a predetermined value.
