Abstract
A polymer dispersion type liquid crystal device includes a pair of transparent substrates; a pair of transparent electrodes provided between the pair of transparent substrates; a liquid crystal layer formed by filling a polymer dispersion type liquid crystal between the pair of transparent electrodes; and a driving circuit that applies a voltage between the pair of transparent electrodes to set the liquid crystal layer to a non-scattering state or a scattering state. The driving circuit applies a direct current voltage that periodically inverts a polarity between the pair of transparent electrodes.
