1. A method for fabricating a liquid crystal device, comprising the steps of:
- fabricating a cell by forming a first wall on at least one of a pair of electrode substrates, forming at least one of a concave portion and a convex portion at a center portion of a region surrounded by the first wall or forming an alignment film having at least one of a concave portion and a convex portion at the center portion of the region surrounded by the first wall, and then disposing the pair of electrode substrates to oppose each other;
injecting a mixture of at least liquid crystal and a curable resin into the cell; and
phase-separating the liquid crystal from the curable resin by first heating the mixture to a homogeneously miscible temperature of the mixture and then gradually cooling the mixture, and curing the curable resin to form a polymer wall on the first wall.

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.

5. A method for fabricating a liquid crystal device, comprising the steps of:
-
fabricating a cell by forming a first wall on at least one of a pair of electrode substrates, forming an alignment film having axial-symmetric orientation axes by phase-separating a mixed material containing two or more different types of polymer materials in a region surrounded by the first wall, and then disposing the pair of electrode substrates to oppose each other; injecting a mixture of at least liquid crystal and a curable resin into the cell; and phase-separating the liquid crystal from the curable resin by first heating the mixture to a homogeneously miscible temperature of the mixture and then gradually cooling the mixture, and curing the curable resin to form a polymer wall on the first wall. - View Dependent Claims (6, 7)
