Abstract:
1. A liquid crystal device comprising: a pair of substrates which are arranged to face each other; a liquid crystal layer interposed between said pair of substrates; an electrode for applying a voltage to the liquid crystal layer, which is provided on a surface, directed to said liquid crystal layer, of each of said pair of substrates; and an orientation film for orienting liquid crystal molecules of said liquid crystal layer, which is formed on a surface, directed to said liquid crystal layer, of each of said electrodes, wherein on a surface of said orientation film, plural grooves are respectively formed in parallel; wherein each of the grooves is separated from an adjacent groove by a stripe-shaped projecting ridge, each stripe-shaped projecting ridge having a substantially flat planar upper surface; wherein in each of the grooves, concave-convex portions for controlling an orientation direction of said liquid crystal layer are periodically formed along a direction in which said grooves extend; and wherein the substantially flat planar upper surface of each projecting ridge projects higher than top parts of the concave-convex portions of the grooves.
