Abstract
An object of the present invention is to provide electronic eyeglass and liquid crystal lens production methods that eliminate the need for forming a liquid crystal injection path in the liquid crystal lens, while making provisions so as to be able to sufficiently maintain a prescribed gap between substrates. The electronic eyeglass and liquid crystal lens production methods includes the steps of placing a sealing agent so as to form a closed planar region on at least one of first and second transparent substrates, dropping a liquid crystal material into an inside space enclosed by the sealing agent, bonding the other of the transparent substrates onto the one transparent substrate on which the liquid crystal material has been dripped, and filling a resin into a space created outside the sealing agent.
