Abstract:
1. An electro-optical device comprising: a scanning line; a data line; a unit circuit that is provided corresponding to intersection of the scanning line and the data line; and a power source line that supplies a power source voltage, the unit circuit including: an electro-optical element that is driven by a driving current; a driving transistor that is arranged between the power source line and the electro-optical element and sets the driving current according to a voltage of a gate of the driving transistor, a first capacitative element that is provided with a first electrode and a second electrode, a first switching element that controls electric connection between the data line and the second electrode based on a control signal that is supplied via the scanning line, and a second capacitative element that is provided with a third electrode and a fourth electrode, the first electrode being connected to the gate of the driving transistor, the third electrode being connected to the gate of the driving transistor, the second and fourth electrodes being formed directly on an insulating layer directly on which the data line is formed and being arranged as electrodes separated from each other, and the fourth electrode being arranged between the data line and the second electrode.
