Optical compensation sheet and its fabrication as well as liquid crystal display device using the same

摘要

An optical compensation sheet for improving the visual characteristics of a liquid crystal display device is disclosed with a liquid crystal display device using such a sheet. The optical compensation sheet contains at least one photopolymerization substance that is sterically or structurally isomerized by light, and has negative uniaxiality, with the optic axis of the sheet intersecting the surface of the sheet. Application of this optical compensation sheet to a TN liquid crystal display device allows it the visual angle property to be improved, thereby providing a high definition liquid crystal display device.
