Abstract:
1. An optical device comprising: a first substrate defining a plane; a first orienting film formed on said first substrate and made from an orienting material having molecules, each of which has a molecular structure that is stretchable and that has a series of connected molecular units, each adjacent pair of said molecular units defining an orienting space therebetween, said molecular units of said molecular structure being aligned along a first axis, said orienting space between each adjacent pair of said molecular units of the molecular structure being oriented in a direction parallel to a second axis, said first and second axes forming a predetermined angle therebetween; and a first optical anisotropical layer formed on said first orienting film and made from a liquid crystal material of rod-like molecules that are spatially affected and oriented by said molecular units and said orienting spaces among said molecular units of said molecular structure such that the projection of the orientation of said rod-like molecules on said plane is parallel to said second axis.
