Patent ID: 7483001

Claim:
An electro-optical device comprising: a plurality of data lines; a plurality of scan lines; a plurality of unit circuits arranged corresponding to intersections of the plurality of data lines and the plurality of scan lines, each of the unit circuits including: a first transistor; an electroluminescence element being connected in series to one of a source and a drain of the first transistor; a second transistor coupled between a gate of the first transistor and one of the source and the drain of the first transistor, the second transistor having a structure to prevent leakage currents during shutoff, and the second transistor being one of an n-type transistor and a p-type transistor; a holding element coupled to the gate of the first transistor, the holding element holding a control voltage, the first transistor supplying a current based on the control voltage to the electroluminescence element, one of the source and the drain of the second transistor being coupled to the holding element; and at least a part of a wiring connecting between the gate of the first transistor and one of a source or a drain of the second transistor and between either of the source or the drain of the first transistor and the other of the source or the drain of the second transistor being formed in a source metal layer formed above a gate metal layer.
