Abstract

A liquid crystal lenticular lens element that: comprises a first substrate, a second substrate that is parallel thereto, a liquid crystal layer that is provided between the substrates, a first electrode that is formed on the liquid crystal layer side of the first substrate, and a second electrode comprising a plurality of stripe-shaped electrodes that are formed on the liquid crystal layer side of the second substrate; and that is characterized by having a configuration in which a stripe-shaped repeating structure that comprises a repeating unit along the arrangement direction of the second electrode is formed and an asymmetrical refractive index distribution is induced on a plane that bisects each of the repeating units in a direction that is perpendicular to the arrangement direction by applying an electrical signal from the exterior to each of the electrodes.
