Liquid crystal device

摘要

A liquid crystal device comprises pixels which are switchable between a white state 5 and a black state 6. Spacers 10 are disposed in gaps between the pixels and are birefringent such that the spacers 10 have the same optical properties as liquid crystal in the black state 6. For example, the spacers 10 may have the same retardation as the liquid crystal layer with an optic axis fixed in the direction of the optic axis of the liquid crystal when in the black state 6.
