Abstract:
A driving circuit for an electrooptical device, comprising:a scanning line above a substrate; a data line above the substrate; a switching device that supplies a pixel electrode with video signals from the data line in response to a signal of the scanning line; a shift-register circuit that includes a plurality of latch circuits for sequentially outputting transfer signals; a plurality of buffer circuits that correspond to output stages of the shift-register circuit, the buffer circuits each including a plurality of inverter logic circuits connected in parallel along a direction intersecting a direction in which the data line extends, the buffer circuits outputting the transfer signals as sampling-control signals; and a plurality of sampling switches connected to a plurality of the data lines, the sampling switches sampling video signals in accordance with the sampling-control signals, and supplying the sampled signals to the corresponding data lines, among which a plurality of sampling switches connected to a plurality of adjacent data lines are simultaneously driven.
