Abstract
An electro-optical device (e.g., a liquid crystal device) includes a data line connected to a switching element provided for each pixel, a sampling transistor that has a gate supplied with a selection signal, a source supplied with an image signal, and a drain connected to the data line, and a monitoring transistor. A gate of the monitoring transistor is supplied with an input signal. A delay signal indicating a delay amount of the selection signal is sent out from a drain of the monitoring transistor. The sampling transistor includes a plurality of transistors connected in parallel to each other along the data line. The monitoring transistor includes one transistor along the data line.
