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.

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.

A method of filling a liquid crystal device with a blended liquid crystal material is set forth. The liquid crystal device is filled by disposing the liquid crystal device having an inlet port, in a vacuum chamber, evacuating the vacuum chamber, supplying the inlet port with the blended liquid crystal material, and elevating the pressure in the chamber to allow the blended liquid crystal material to fill the liquid crystal device through the inlet port by virtue of the differential pressure between the inside and the outside of the liquid crystal device, with the temperature of the blended liquid crystal material being maintained, until the liquid crystal device is completely filled with the blended liquid crystal material, at a temperature higher than the transition temperature of any one of the constituents of the blended liquid crystal material so that the blended liquid crystal material is transformed in its isotropic phase.
