Liquid crystal cells and lenses having a variable resulting pre-tilt across two or more areas of the cell, and in particular, cells and lenses are provided wherein a resulting pre-tilt is varied across the cell according to any desired birefringence profile that can be utilized in liquid crystalline optical elements and liquid crystal displays. Methods of fabrication of the liquid crystal cells with variable resulting pre-tilt are disclosed.

Photo-patterned pre-tilt liquid crystal cells, lenses and methods

An elliptically polarizing plate, comprising a polarizer, a first optical anisotropic layer having positive refractive index anisotropy and an optical axis of the anisotropy that is tilted, and a second optical anisotropic layer having negative refractive index anisotropy and an optical axis that is tilted, have accurate retardation compensation of a liquid crystal cell, and the liquid crystal display maintains a display contrast having a sufficient visibility when the viewing angle is changed and which does not generate colorization.

Elliptically polarizing plate and liquid crystal display

An optical compensation film for a liquid crystal display is provided wherein the film is a polymer that is capable of producing light induced anisotropy. The film is irradiated with light to form an optical axis or axes.
