<p>A liquid crystal device comprises a pair of substrates (1, 2) each having a major surface (3, 4) spaced from and facing the other (4, 3) and a peripheral seal (9) defining a cavity (10) containing a liquid crystal material (11). The seal is formed by a thermoplastic gasket which is located in a groove (20) sunk into a major surface of a substrate. This arrangement can provide improved control of seal width and/or location on curved or uneven substrates such as eye wear or silicon backplane spatial light modulators. <IMAGE></p> |
