Abstract
An anti-ferroelectric liquid crystal device includes a first substrate on which pixel electrodes and an alignment film are formed, and a second substrate on which an opposite electrode and another alignment film are formed. These substrates are arranged to face each other. An anti-ferroelectric liquid crystal is sealed in a space defined between the substrates. The pixel electrodes arranged on the first substrate are connected to thin-film transistors formed on the first substrate. The thin-film transistors are selected by being supplied with control signals at their gates and data signals are supplied to their drains to apply data potentials to the pixel electrodes.
