PURPOSE:To prevent foaming of liquid crystals by injecting the liquid crystals at an ordinary temp. into a liquid crystal cell through the liquid crystal injecting port provided to said cell, sealing said port with a sealing material and hardening the sealing material in the stage of shrinking the liquid crystals under the conditions wherein the entire part of the liquid crystal cell is maintained at temp. lower tha the ordinary temp. CONSTITUTION:Transparent electrodes 1 and a sealing material 2 are set on glass substrates 4, 5 and a liquid crystal material 7 is injected through an injecting port 3. The liquid crystals 7 oozed to the outside through the port 3 are removed by blowing gaseous N2 and the port is sealed by silicone adhesive 8. These stages are executed at 25 deg.C ordinary temp. Thereafter the entire part of the liquid crystal is put into a thermostatic chamber kept at -5-15 deg.C for 4hr to allow the liquid crystals 7 to shrink. The adhesive 8 is sucked to the inside and harden in this stage. When the temp. for allowing the liquid crystals to shrink is kept at <=10 deg.C, the fraction defective by foaming of the liquid crystal cell is reduced by half and the yield is markedly improved. |
