Abstract:
A driving circuit for an electro-optical device having plural data lines and plural scanning lines which intersect each other on a substrate, said driving circuit comprising:plural sampling switches provided on said substrate, the sampling switches sampling image signals in accordance with a sampling control signal and supplying the image signals to said plural data lines, respectively, and a data line driving circuit that supplies said sampling control signal simultaneously to each group of sampling switches connected to n (n is an integer of 2 or more) data lines adjacent to said plural sampling switches, said data line driving circuit comprising: a shift register circuit that sequentially outputs a transfer signal from each of a plurality of latch circuits, and a buffer circuit that outputs said transfer signal as said sampling control signal, said buffer circuit comprising at least one transistor extended in a same direction as a direction in which a width of a channel of the transistor would intersect the data lines.
