Abstract
The present application relates to an optical element, a driving method of the optical element, a transmittance-variable device and a use thereof. In one example, the present application may provide a driving method suppressing a back-flow phenomenon caused by a bulk liquid crystal compound even when a cell gap of a liquid crystal layer becomes thick. The driving method may ensure excellent response speeds and driving characteristics.
