摘要： A colorless liquid crystalline compound having at least one 6-membered ring and non-cyclic end groups in the molecular skeleton, said 6-membered ring containing two or more carbon atoms, at least one of which is directly bonded to a methylene group of a non-cyclic group having an alkoxy group at another end has a wide mesomorphic range. When said colorless liquid crystalline compound is mixed with a liquid crystal composition. the resulting mixture also has an enlarged mesomorphic range and in almost all cases has a reduced viscosity.

摘要： An optical apparatus comprises an optical device (10) having an optically functional material (6) sandwiched between a pair of substrates (3) with electrodes (5) formed on opposing surfaces. The optically functional material has such a characteristic that intensity of light issuing from the optical device changes asymmetrically in response to inversion of the polarity of an applied external field. Pulse voltages of one polarity for determining the intensity of the issuing light and pulse voltages of an opposite polarity are applied from a source (8) at a predetermined period (T) so that an average voltage is zeroed within the predetermined period. The issuing light intensity under the application of the pulse voltages of one polarity and the issuing light intensity under the application of the other pulse voltages are selected or changed by a switching unit (20).

摘要： When the reflection density of the colorants of an ink layer is 1.3 after transfer onto a recording paper, a reflectance of yellow colorant lies in between two diagrams (D₁, D₂) shown in Fig. 1, a reflectance of magenta colorant lies in between two diagrams (D₃, D₄) shown in Fig. 2, and a reflectance of cyan colant lies in between two diagrams (D₅, D₆) shown in Fig. 3. A color ink sheet realizes an excellent hue, a high luminance factor and high chroma. A wide color specification range and clear image having a high color reproducibility is obtained.
