| 20100149446 | POLYMER-STABILIZED LIQUID CRYSTAL COMPOSITION, LIQUID CRYSTAL DISPLAY DEVICE, METHOD FOR PRODUCING LIQUID CRYSTAL DISPLAY DEVICE - An object of the present invention is to obtain a polymer-stabilized liquid crystal composition which can suppress dependency of a driving voltage on a temperature by decreasing the driving voltage. To a low-molecular liquid crystal compound, a chiral compound, and a specific acrylate and a polymerizable liquid crystal compound as polymerizable acrylate compounds are added, to prepare a polymer-stabilized liquid crystal composition. By subjecting the polymer-stabilized liquid crystal composition to ultraviolet exposure while maintaining a desired alignment state to form a polymer chain in a liquid crystal phase, a polymer-stabilized liquid crystal display device containing a low-molecular liquid crystal in a stabilized alignment state is obtained. | 06-17-2010 |
| 20100189930 | COMPOSITION FOR PHOTO-ALIGNMENT FILM, PHOTO-ALIGNMENT FILM, AND OPTICALLY ANISOTROPIC MEDIUM - According to a composition for a photo-alignment film of the present invention, which includes an azo compound and a polymer that exhibits mutual solubility with the azo compound, an adhesion to a substrate, particularly to a plastic substrate, is improved within both a photo-alignment film having a haze of not more than 1 obtained by forming a layer of the above composition for a photo-alignment film on a substrate and subsequently irradiating the layer with light to generate a liquid crystal alignment ability; and an optically anisotropic medium, wherein a layer (A) obtained by irradiating a layer of the above composition for a photo-alignment film with light to generate a liquid crystal alignment ability, and a polymer layer (B) obtained by polymerizing a liquid crystal compound having a polymerizable group in an aligned state generated by the layer (A) are bonded and laminated together by covalent bonds. | 07-29-2010 |
