In an electro-optical device including a scanning line driving circuit, the scanning line driving circuit includes a transfer direction control circuit for controlling the direction of transfer of a start pulse, a shift register for shifting the start pulse, supplied by the transfer direction control circuit, in response to a clock signal, and an output selection circuit for selecting the output signal of the shift register in accordance with a first enable signal and a second enable signal. A decimation process and a stretching process are performed by controlling the first enable signal and the second enable signal in accordance with the video line count of an input video signal.
