Abstract
In a method of manufacturing a liquid crystal device, first and second substrates are provided. A UV-curable adhesive is applied to a peripheral portion of at least one of the opposed surfaces the first and second substrates, the UV-curable adhesive having a glass transition point. The first substrate is adhered to the second substrate so as to define a predetermined spacing therebetween. The adhesive is cured by irradiation with UV rays and thereafter heated at a temperature higher than the glass transition point of the adhesive. A liquid crystal is then sealed in the predetermined spacing between the first and second substrates.
