ABSTRACT:
The present invention provides a liquid crystal electro-optical device that response time is short and voltage holding rate is not lowered. One feature of the invention is a first substrate, a first electrode over the first substrate, a first orientation film covering the first electrode, and a second substrate opposed to the first substrate and provided with a second electrode, a second orientation film covering the second electrode, a liquid crystal layer interposed between the first and the second substrates, wherein the liquid crystal layer is formed of a mixture of a nematic liquid crystal and a liquid crystal having a smectic phase, wherein a ratio of a liquid crystal having a smectic phase in the mixture is 20 weight % or less, and wherein an arithmetic average of rise response time and fall response time of a plurality of liquid crystal molecules in the mixture is 8 msec or less.
