| 摘要 |
A method suitable for producing large scale light modulating liquid crystal devices having a very thin layer, say 15.mu.m thick, of liquid crystal containing material (6), preferably a mixture capable of forming polymer stabilised liquid crystal ("PSCT") material, sandwiched between two substrates (2, 4), at least one of which is glass. The liquid crystal containing material (6) is applied to the first substrate (2) before the second substrate (4) is brought into contact, and the substrates (2, 4) are compressed, for instance between rollers (18, 22), to achieve the required thickness of liquid crystal material. Spacers keep the substrates (2, 4) the requisite distance apart. Liquid crystal containing material (6) capable of forming PSCT material also requires polymerising, say, by exposing the compressed sandwich to UV radiation.
