US 5,474,629 A · Method for manufacturing a liquid crystal device

Abstract

A method for manufacturing a liquid crystal device, particularly a dispersion-type liquid crystal electrooptical device, which comprises a pair of substrates having incorporated therebetween a light-control layer comprising a transparent solid and a liquid crystal material and spacers, said substrates having provided thereon electrode layers and at least one of the substrates being transparent, is disclosed. The method comprises: coating the electrode layer side of one of the substrates with a material which gives the light-control layer; and, laminating and fixing the pair of substrates to give a predetermined layered structure. The spacers are uniformly disposed between the substrates by dispersing spacers on one of the electrode layers or on the light-control layer or applying a mixture comprising spacers, a liquid crystal material and a material for providing a transparent solid on one of the electrode layers. The process is economical and enables large-sealed liquid crystal electrooptical devices which can provide uniform displays, at an extremely few steps comprising coating once the substrate with a material for the light-control layer.
