PREPARATION OF AN OPTICAL COMPENSATION SHEET USING PHOTOSENSITIVE COMPOUNDS

摘要

A process for preparation of an optical compensatory sheet is disclosed. The process comprises the steps in order of: coating a support with a photosensitive compound; exposing the photosensitive compound to beams of linearly polarized light emitted from a semiconductor laser (11) to form an orientation layer; coating the orientation layer with a liquid crystal composition containing polymerizable liquid crystal molecules; aligning the liquid crystal molecules to form an optically anisotropic layer; and then polymerizing the liquid crystal molecules to fix alignment.
