PURPOSE:To secure orientation condition of liquid crystals in good condition without causing adverse effect on the liquid crystals due to a sealing resin for sealing an injecting port of the liquid crystals by injecting pieces of inactive resin under pressure through the injecting port after injecting the liquid crystals through the injecting port of the liquid crystals, then sealing the liquid crystals with the sealing resin. CONSTITUTION:A sealing material 3 is provided to three edges of a square superposed surface of an upper 1, and lower 2 substrates. A space where this sealing material is absent is used as an injecting port 4 of liquid crystals. Then, liquid crystals such as ferroelectric liquid crystals having chiral smectic C phase are injected from the injecting port 4. Since, in this case, the injecting port 4 is so wide as corresponding to one edge of the superposed surface of the upper and lower substrates 1, 2, even such ferroelectric liquid crystals having high viscosity can be injected quickly. When the injection of the liquid crystals is finished, pieces of an inactive resin 5 are forced under pressure through the injecting port 4, then the injecting port 4 is closed. By this process, dissolution of the sealing resin into the liquid crystal is prevented almost completely, preventing also defective orientation near the injecting port, also.
