ABSTRACT:
An improved method for manufacturing liquid crystal devices is described. The method comprises mating a pair of substrates with an inner space therebetween, sealing the periphery of the mated substrates save for inlet ports, placing the mated substrates in a vacuum chamber, evacuating air from the inner space between the substrates by virtue of the differential pressure between the inner space and the vacuum chamber, pouring a liquid crystal material into the inlet ports, introducing the liquid crystal material into the inner space by elevating the pressure of the vacuum chamber at an elevated temperature, cooling the liquid crystal material, and closing the inlet ports by means of a sealing member. The removal of the superfluous portion of the liquid crystal material is done only after closing of the inlet ports.
