  • Double-layer liquid crystal lens
    Patent number: 8035794
    Abstract: A double-layer liquid crystal lens comprises a first transparent substrate, a second transparent substrate, a third transparent substrate, a first liquid crystal layer interposed between the first and the second transparent substrates, and a second liquid crystal layer interposed between the second and the third transparent substrates. The upper side of the first transparent substrate is provided with a transparent ITO electrode and an alignment film disposed on the transparent electrode. Each of the upper and the lower sides of the second transparent substrate is provided with a alignment film. The upper side of the third transparent substrate is provided with an apertured electrode while the lower side thereof is provided with an alignment film. The first and the third transparent substrates are made of glass while the second transparent substrate is made of plastic material.
