PURPOSE:To obtain a prescribed color tone difference even by the same applied voltage, and also, to change it to other color tone, as well, by constituting a liquid crystal layer of two or more liquid crystal areas whose optical anisotropy (DELTAn) is different from each other. CONSTITUTION:On a liquid crystal receiver use container 18, a liquid crystal cell is held so as not to be immersed, and they are set to a vacuum injector. After pressure reduction and absorption, at the time of opening to the air, the liquid crystal cell 19 is made to descend to a position where it is immersed into a liquid crystal, and simultaneously, cocks 14, 15 are opened. A liquid crystal A in a container A12 decreases, a liquic crystal B of a container B13 flows into the container A12 and both the liquid crystals A, B are mixed. Accordingly, a mixture of both the liquid crystals is injected into the liquid crystal cell 19, also susequently, a mixed liquid crystal (namely, a mixed liquid crystal whose DELTAn is large gradually) in which a density of the liquid crystal B has become larger gradually is injected continuously into the liquid crystal cell, and in the end, the liquid crystal B is injected to the lowest end of the liquid crystal cell 19. Subsequently, a variable color liquid crystal cell is obtained by sticking a polarizing plate to cloth, on both sides of this liquid crystal element.
