Abstract
The invention provides for the efficient use a substrate region in a liquid crystal device with built-in driving circuits which simultaneously drives a plurality of data lines, etc. One of substrates used for the liquid crystal device may include a plurality of latch circuits for sequentially outputting transfer signals, buffer circuits for outputting sampling-control signals via signal lines by performing wave shaping on the transfer signals input via wires, and sampling switches for sampling, in accordance with the sampling-control signals, video signals supplied to video-signal lines, and for supplying the sampled signals to the corresponding data lines. The buffer circuits each comprise inverters connected in series in three stages in a direction in which the data lines extend, and the inverter in each stage comprise seven inverters connected in parallel in a direction intersecting the extended direction of the data lines.
