1. A process for forming a liquid crystal display, which process comprises:
- (a) forming a plurality of cells;
(b) filling said cells with a liquid crystal composition comprising a chiral material;
(c) overcoating a sealing composition onto the entire surface of the liquid crystal composition in said cells wherein said sealing composition is not attached to a conductive substrate; and
(d) hardening said sealing composition to enclose said liquid crystal composition within said cells;
wherein said process is carried out continuously.
