PURPOSE: To make cell thickness uniform and to remove mixed foams by successively pressing a liquid crystal display cell filled with the liquid crystals with elastic press members.
CONSTITUTION: Transparent electrodes 3, 4 of ITO films are formed on org. polymer film substrates 1, 2, and further, films 5 for orienting liquid crystals are formed using SiO, SiO2, or the like. Spacers 6 are scattered uniformly on the substrate 1, a sealant 7 is screen printed on the substrate 2, both substrates are pasted and filled with the liquid crystals. At that time, foams 9 are involved in the inside. After filling the liquid crystals, the cell thus formed is pressed with elastic rolls 11 successively from the side opposite to an opening 10 for filling. Consequently, the interval of the substrates 1, 2 is reduced gradually by being pressed up to the distance determined by the diameter of the spacers 6, an excess of the liquid crystals are ejected out of the opening 10, and at that time, the foams 9 are removed. As said rolls, an elastic material, such as urethane rubber, silicone rubber, chloroprene rubber, or natural rubber, are used.
