Abstract

PURPOSE:To function liquid crystal as a transparent and light shielding filter by simple switching of applying a voltage to the liquid crystal or automatic switching using light rays, through the use of the decrease in light transmissivity owing to the dynamic scatttering mode or electric field effect mode of the liquid crystal.
