Abstract:
A driving circuit for an electro-optical device having plural data lines and plural scanning lines which intersect each other above a substrate, the driving circuit comprising:plural image signal lines provided above the substrate; plural sampling switches provided in groups above the substrate, the sampling switches driven simultaneously in each group in accordance with a sampling control signal and supplying the image signals to the plural data lines, respectively; plural sampling control signal lines connected to each group of the sampling switches; and a data line driving circuit that supplies the sampling control signal the sampling control signal lines, the data line driving circuit including: a shift register circuit that sequentially outputs a transfer signal from each of a plurality of latch circuits, and a plurality of buffer circuits that are respectively connected to the latch circuits between the sampling control signal lines, that outputs the transfer signal as the sampling control signal, each buffer circuit including a plurality of inverters, an input side of each inverter and an output side of each inverter extending in a same direction as a direction intersecting an extending direction of at least one of the data lines.
