LIQUID CRYSTAL DISPLAY DEVICE AND RETARDATION FOIL

摘要

The invention relates to a liquid crystal display cell (1) having a compensation layer (9) of (polymer) material deposited from the gaseous phase such as, for example (chlorinated) polymerized poly-p-xylylene (PPX). To obtain a smaller angle dependence, the birefringence of the compensation layer can be rendered complementay to that associated with a given voltage across the liquid crystal cell by giving the optical axis of the compensation layer an angle to the direction transverse to the cell.
