CHEMISORPTIVE SUBSTANCE, ALIGNED LIQUID-CRYSTAL FILM AND LIQUID-CRYSTAL DISPLAY ELEMENT BOTH MADE BY USING THE SAME, AND PROCESSES FOR PRODUCING THESE |
摘要 |
The present invention provides a new chemical adsorbent which can form an extremely thin and transparent film in nanometer order which is fixed uniformly and firmly on a substrate, and give an alignment characteristic of high thermal stability to the thin film; as well as a liquid crystal alignment layer and a liquid crystal display device having a desirable alignment characteristic, a superior alignment control force over a liquid crystal molecule, and a superior thermal stability by using the above-mentioned chemical adsorbent. This purpose can be actualized by developing a new compound which is transparent and stable in a range of a visible ray (a wavelength from 400 nm to 700 nm), and has a photosensitivity in a range of an ultraviolet ray and a far-ultraviolet ray (a wavelength from 200 nm to 400 nm), and can form a thin film in a monolayer through a chemisorption on a substrate. <IMAGE> |
