Recent progress in optical alignment for liquid crystal displays

Non-contact optical alignment technology has been identified by the liquid crystal display (LCD) industry as one of the key technologies for manufacturing next generation wide viewing angle, high resolution LCDs. In this paper we review the field of optical alignment technology. We will report our progress in optical alignment materials and equipment development. Data on optically aligned twisted nematic, super-twisted nematic, vertical alignment, and in-plane switching test cells will be presented.
