Patent number: 6787201Abstract: A chiral nematic liquid crystal composition that exhibits a cholesteric phase, said chiral nematic crystal composition comprising 55 wt % to 90 wt % of a nematic liquid crystal composition that comprises, as main components thereof, a liquid crystal ester compound and a liquid crystal pyrimidine compound, wherein said liquid crystal ester compound does not include a tolan skeleton therein and said liquid crystal pyrimidine compound includes a fluorine atom therein; and 10 wt % to 45 wt % of at least one chiral agent. A liquid crystal light modulating apparatus comprising a pair of substrates at least one of which is transparent; and the chiral nematic liquid crystal composition disposed between the substrates.Type: GrantFiled: September 10, 2002Date of Patent: September 7, 2004Assignee: Minolta Co., Ltd.Inventors: Akihito Hisamitsu, Takeshi Kitahora, Fumie Motoori, Hideaki Ueda

Patent number: 6683672Abstract: A chiral nematic liquid crystal composition which contains a nematic liquid crystal mixture and a chiral agent, which exhibits a cholesteric phase at room temperature and which selectively reflects light of a specified wavelength, wherein the chiral agent has an anisotropy of dielectric constant within a range from 12 to 60. Such a chiral nematic liquid crystal composition may have a larger anisotropy of dielectric constant than the nematic liquid crystal mixture before being mixed with the chiral agent. Alternatively, in such a chiral nematic liquid crystal composition, the anisotropy of dielectric constant of the chiral agent may be larger than that of the nematic liquid crystal mixture. By filling such a chiral nematic liquid crystal composition between transparent substrates, a liquid crystal cell is fabricated, and by stacking such liquid crystal cells in three layers, a reflective type full-color liquid crystal display can be produced.Type: GrantFiled: May 23, 2002Date of Patent: January 27, 2004Assignee: Minolta Co., Ltd.Inventors: Hideaki Ueda, Takeshi Kitahora, Fumie Motoori

Patent number: 6602563Abstract: A liquid crystal display which carries out matrix driving of a chiral nematic liquid crystal composition, which is capable of displaying an image theron continuously after an electric field applied thereto is turned off, by applying an electric field to the liquid crystal composition through a plurality of scan electrodes and a plurality of data electrodes which face and cross each other with the liquid crystal composition in-between. The nematic liquid crystal which is the main element of the liquid crystal composition mainly contains a liquid crystalline ester compound, a liquid crystalline stilbene compound, a liquid crystalline terphenyl compound or a liquid crystalline tolane compound.Type: GrantFiled: May 17, 2001Date of Patent: August 5, 2003Assignee: Minolta Co., Ltd.Inventors: Nobuyuki Kobayashi, Takeshi Kitahora, Fumie Motoori, Hideaki Ueda
