Abstract
A liquid crystal device is produced through the steps of: providing a pair of glass substrates each having thereon transparent electrodes, applying the substrates to each other with a thermosetting sealant so that the electrodes thereon oppose each other with a prescribed spacing therebetween, and disposing a liquid crystal at the spacing. In the process, prior to the step of applying the substrates, the thermosetting sealant is applied onto a prescribed part of one of the substrates, and the pair of substrates are both pre-baked under an identical condition for pre-baking the thermosetting sealant. As a result, the two substrates constituting the liquid crystal device are caused to have an identical thermal history so that the resultant liquid crystal device is provided with a uniform alignment characteristic free from difference in alignment power between the substrates and a good application accuracy between the substrates.
