example 1

[0043] A vertically aligned liquid crystal device was fabricated as follows. The glass substrate on which the transparent electrode is provided and the Si driving circuit substrate provided with the aluminum electrode are cleaned and then introduced into a vapor deposition apparatus, and passed through an inclined vapor deposition at a vapor deposition angle in the range of 45 to 60°. Phase Deposition of SiO as Liquid Crystal Alignment Film 2 A film is formed on a substrate. The vapor deposition was controlled so that the liquid crystal alignment film was 50 nm thick and the pretilt angle of the liquid crystal was about 2.5°. Thereafter, the two substrates provided with the respective liquid crystal alignment films were passed through an adhesive containing glass beads mixed therein (UV curable adhesive produced by Three Bond Co., Ltd., which has a glass transition of 140° C. temperature) were used to bond each other such that the spacing between the substrates was 1.9 μm. ...

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.

Description

technical field [0001] The present invention relates to a manufacturing method of a liquid crystal device, a liquid crystal device, a liquid crystal display, and a projection system, the manufacturing method of the liquid crystal device allows two substrates to be bonded to each other at a predetermined distance therebetween and drives a liquid crystal sealed between the substrates . Background technique [0002] In the liquid crystal display device described, for example, in Japanese Patent Laid-Open No. 2004-333986, adhesives for bonding two substrates to each other are classified into two types, namely, those having UV curable components Both types with heat curable components (UV / heat curable types) and types with only UV curable components (UV curable types). [0003] When using the former type, heat treatment for curing the adhesive is necessary. On the other hand, when using the latter type, heat treatment is not necessary, but ensures a more reliable curing. If un...
