Patent ID: 7932876

Claim:
An electro-optical device comprising: a plurality of pixel circuits each including a light-emitting element and a driving transistor for driving the light-emitting element; data lines that are connected to the plurality of pixel circuits and that supply data signals representing light-emitting gray-scale levels to gate electrodes of the driving transistors in the plurality of pixel circuits; and a data line driving circuit that is provided outside the plurality of pixel circuits and supplies the data signals to the pixel circuits through the data lines, wherein the data line driving circuit applies to each pixel circuit in a predetermined sequence two forward frame periods supplying a data signal having a forward bias voltage for making the light-emitting element emit light and a backward frame period supplying a data signal having a backward bias voltage for making the light-emitting element not emit light, and drives each of the plurality of pixel circuits, the forward frame periods and the backward frame period each is a single frame period, the two forward frame periods are consecutive, the backward frame period is applied immediately after the two consecutive forward frame periods, the data line driving circuit applies the backward frame period once after applying the forward frame periods to each of the pixel circuits M times (M is an integer equal to or greater than 2, and determines the backward bias voltage applied to the data line in the backward frame period in accordance with a sum of N forward bias voltages applied to the data line in the forward frame periods for the M times right before the backward frame period, and the data line driving circuit carries out switching between the forward frame periods and the backward frame period in the predetermined sequence.
