Abstract

In a liquid crystal device in which a pair of substrates each having an electrode and a liquid crystal orientation control layer are disposed opposite to each other leaving a predetermined gap therebetween and liquid crystal is disposed in the gap, a plurality of grooves are formed on each of the inner surface contacting the liquid crystal, the section of the inner surfaces in a direction along the grooves has such a shape that repetitive asymmetrical projections are formed and the radius of curvature of the grooves in a direction intersecting the grooves is set to 0.1 &mgr;m or more.
