ABSTRACT:
A liquid crystal electro-optical device has a first substrate on which a plurality of pixel electrodes to which thin-film transistors are connected are arranged in matrix form, a second substrate opposed to the first substrate and provided with an opposed electrode, and a ferroelectric or antiferroelectric liquid crystal material provided between the first and second substrates. A voltage value between a selected one of the pixel electrodes and the opposed electrode is detected, and a voltage value corresponding to the detected voltage value is applied to the selected pixel electrode.
