Abstract:
In order to improve the state of image irregularities of a liquid crystal panel, a plasma treatment is performed for an alignment film using a treatment gas such as hydrogen and/or deuterium, or a surface treatment is performed in which an alignment film is immersed in deuterium oxide. As a result, moisture contained in the alignment film is removed, and re-adsorption of moisture is also suppressed, thereby reducing image irregularities.
