Abstract
There is provided a pair of transparent upper and lower glass substrates which are disposed apart from each other so as to form a space there-between, a pair of electrodes provided on the underside of the upper substrate and on the upper surface of the lower substrate. A plurality of circular holes are formed in each of the electrodes. A liquid crystal is charged in the space. The liquid crystal has a lens construction formed by an electric current and hardened by irradiation of ultraviolet rays.
