Abstract
A liquid crystal device includes a liquid crystal panel including a liquid crystal layer as a first liquid crystal layer, a first polarizing element, a second polarizing element, a first phase difference adjusting element arranged between the first polarizing element and the liquid crystal panel and including a liquid crystal layer as a second liquid crystal layer, a second phase difference adjusting element arranged between the liquid crystal panel and the second polarizing element and including a liquid crystal layer as a third liquid crystal layer, and a first phase difference controlling element driving unit and a second phase difference controlling element driving unit as control units configured to control a value of a voltage applied to the first phase difference adjusting element and the second phase difference adjusting element, based on image data input to the liquid crystal panel.
