An improved liquid crystal device and manufacturing method for same are described. In the device, a pair of substrates, between which a liquid crystal layer is disposed, is joined with pillars inbetween functioning as spacers which are provided of photocurable resin by photolithography. With this structure, the spacers can be in surface contact with the inside surfaces of the substrates on which electrode arrangement and active devices are formed.

In the device, a pair of substrates, between which a liquid crystal layer is disposed, is joined with pillars inbetween functioning as spacers which are provided of photocurable resin by photolithography. With this structure, the spacers can be in surface contact with the inside surfaces of :he substrates on which electrode arrangement and active devices are formed.

A method for manufacturing a liquid crystal device in which a pair of substrates are placed in a vacuum chamber, with at least one inlet port provided for communicating with an inner space between the pair of substrates. The vacuum chamber is evacuated and a material including liquid crystals is supplied to the inlet port. The pressure of the chamber is then elevated such that the liquid crystal and other materials are introduced into the space between the pair of substrates by the use of differential pressure between the inside and outside of the space between the substrates. The material including the liquid crystals is maintained at a sufficiently high temperature such that the liquid crystals exhibit isotropic phases.

Method of filling a liquid crystal device with introduction of liquid

A liquid crystal display wherein chromatic aberration is reduced by superimposing an anisotropic film on a ferroelectric liquid crystal where the anisotropic film is located between a pair of polarizing plates and is selected from the group consisting of polycarbonates, polyvinylalcohol, polyacetates, polyethylene, polyester, polyimides, polyamides, polyvinylchloride, and polystyrene.

Liquid crystal device

An improved method of filling a liquid crystal device with a blended ferroelectric liquid crystal material is disclosed. The method includes the step of disposing the blended ferroelectric liquid crystal material in an inner space formed in the liquid crystal device, with the temperature of the blended liquid crystal being maintained during the disposing step at a temperature higher than the transition temperature of any constituent of the blended liquid crystal material such that the blended liquid crystal material is transformed in its isotropic phase.

Method of filling a liquid crystal device with ferroelectric liquid

A method of filling a liquid crystal device including a pair of parallel substrates having external surfaces with a liquid crystal material is set forth. The liquid crystal device is filled by disposing the liquid crystal device in a vacuum chamber between a pair of opposed parallel plates, evacuating the vacuum chamber, supplying the liquid crystal material to an inlet of the device, elevating the pressure in the chamber to allow the liquid crystal material to enter a space formed between the parallel substrates through the inlet by virtue of a differential pressure between the inside and the outside of the liquid crystal device, and applying opposed pressure with the parallel plates to the external surfaces of the parallel substrates respectively in order to form a uniform liquid crystal device. With the external pressure being applied to compensate for the expansion of the liquid crystal device during the elevation of the pressure within the vacuum chamber.
