ABSTRACT:
A pair of substrates each provided with an electrode film are adhered to each other at their peripheral portions through a sealing material to form an envelope. A liquid crystal material is injected into the envelope from a liquid crystal material injection port which is provided in a localized part of the sealing material. Then, the envelope is heated to a temperature higher than the normal room temperature, and a photosensitive curing adhesive is applied to the injection port while maintaining the envelope at the elevated temperature. After the application of the adhesive, the envelope is cooled to a temperature in the vicinity of the normal room temperature. Subsequently, the adhesive is hardened through irradiation of light at a temperature in the vicinity of the normal room temperature to hermetically seal the injection port, thereby finishing a liquid crystal display cell. Alternatively, the photo-sensitive curing adhesive may be applied at a temperature in the vicinity of the normal room temperature and then hardened at a temperature lower than normal room temperature.
