Abstract
Cholesteric liquid crystal display (Ch-LCD) devices with actuating thin-film driving elements are presented. The Ch-LCD device includes a first substrate and an opposing second substrate. An actuating thin-film structure is disposed on the first substrate. A cholesteric liquid crystal layer is filled between the first substrate and the second substrate. A common electrode is disposed on the second substrate. In operation, the actuating thin-film structure is deformed to drive phase transition of the cholesteric liquid crystal layer.
