Title: METHOD FOR PRODUCING LIQUID CRYSTAL ELEMENT AND LIQUID CRYSTAL ALIGNING AGENT
Abstract:
According to the present invention, a liquid crystal element is produced by a method which comprises: a step for applying a liquid crystal aligning agent to a first substrate and a second substrate; a step for heating the first substrate and the second substrate after the application of the liquid crystal aligning agent; and a step for configuring a liquid crystal cell by arranging the first substrate and the second substrate after the heating such that surfaces on which the liquid crystal aligning agent is applied face each other. This method is configured such that: the liquid crystal aligning agent contains a compound having a thermally cleavable group that is cleaved by means of heating; and a high-temperature heat treatment, wherein one of the first substrate and the second substrate is heated at a higher temperature than the other one, is carried out in the step for heating the substrates.
