PRODUCTION OF LIQUID CRYSTAL ELEMENT

摘要

PURPOSE:To prevent the generation of a partial operation defect by absorbing an additive to a liquid crystal to the oriented films formed on substrates then positioning the surfaces of the substrates to face each other, sealing the liquid crystal therebetween and dissolving the additive into the liquid crystal thereby distributing the additive over the entire part of the liquid crystal operation part. CONSTITUTION:Electrodes 2 are formed on the respective surfaces of a pair of the substrates 11, 12 then the oriented films 3 are disposed thereon. Part of the additive 41 to the liquid crystal is adsorbed to the surface of at least one of the films 3 and thereafter the surfaces of a pair of the substrates 11 and 12 are positioned to face each other. The liquid crystal 50 is sealed therebetween and the additive 41 is dissolved into the liquid crystal 50. The additive 41 can be uniformly distributed into the crystal 50 when the liquid crystal element is assembled in the above-mentioned manner. The generation of the partial operation defect of the liquid crystal element is thus prevented and the element having the good accuracy is obtd. even if the element has a large area.
