Patent ID: 6989826

Claim:
An electro-optical device which is driven by an active matrix driving method, comprising: a unit circuit matrix in which a plurality of unit circuits are arranged in the form of a matrix, each unit circuit including a light-emitting element and a circuit for adjusting an emission level of light to be emitted by the light-emitting element; a plurality of scan lines which are respectively connected to the unit circuits, and which are arranged along a row direction of the unit circuit matrix; a plurality of data lines which are respectively connected to the unit circuits, and which are arranged along a column direction of the unit circuit matrix; a scan line driving circuit, connected to the plurality of scan lines, for selecting one row of the unit circuit matrix; a data signal generating circuit for generating a data signal in accordance with the emission level of the light to be emitted by the light-emitting element, and outputting the data signal onto at least one data line among the plurality of data lines; and a charging/discharging accelerating section which is capable of accelerating charging or discharging of a data line through which the data signal is supplied to at least one unit circuit that is present in the row selected by the scan line driving circuit, wherein the light-emitting elements are current-driven type elements in which the light emission level depends on a current value flowing through the element, each unit circuit comprise: a driving transistor having a control electrode, the driving transistor being installed in a path of the current that flows through the light-emitting element, and a storage capacitor, connected to the control electrode of the driving transistor, for setting the current value that flows through the light-emitting element by holding an electric charge that corresponds to an operating state of the driving transistor, and wherein the accumulated charge in the storage capacitor is adjusted by the data signal.
