Abstract

A liquid crystal device includes a pair of electrode substrates opposing each other, a polymer wall, and a liquid crystal region surrounded by the polymer wall, the polymer wall and the liquid crystal region being sandwiched by the pair of electrode substrates. At least one of a concave portion and a convex portion is formed on a surface of at least one of the pair of electrode substrates facing the liquid crystal region, and liquid crystal molecules are oriented in the liquid crystal region axial-symmetrically around the vicinity of the at least one of concave portion and convex portion as an axis vertical to the electrode substrates.
