A method for making an optical device includes the steps of: rubbing an orienting film so as to stretch the molecular structure thereof and so as to permit the molecular units of the molecular structure to be aligned along a first axis and to permit the orienting space between each adjacent pair of the molecular units of the molecular structure to be oriented in a direction parallel to a second axis; and forming an optical anisotropical layer on the orienting film by applying a liquid crystal film of rod-like molecules on the orienting film which orients the rod-like molecules by virtue of spatial effect of the molecular units and the orienting spaces.

Optical device and method for making the same

An optical compensator includes a C-plate adapted to be coupled to a liquid crystal cell and made from a polymer. The C-plate has a layer thickness ranging from 5 to 60 &#x3bc;m. The polymer is polyvinyl alcohol, has a polymerization degree greater than 2000 and less than 5000, and is cross-linked so that the C-plate has an optical axis substantially parallel to the direction of normally incident light, and so that the C-plate has a plate retardation, along the layer thickness of the C-plate, greater than 60 nm.
