Description

EXAMPLES

(1) In order to evaluate characteristics of a composition and a compound to be contained in the composition, the composition and the compound were made as a measurement object. When the measurement object was the composition, the measurement object was measured as is, and values obtained were described. When the measurement object was the compound, a sample for measurement was prepared by mixing the compound (15% by weight) into mother liquid crystals (85% by weight). Characteristic values of the compound were calculated from values obtained by measurement, according to an extrapolation method: (extrapolated value)=[(measured value of a sample for measurement)0.85(measured value of mother liquid crystals)]/0.15. When a smectic phase (or crystals) precipitated at the ratio thereof at 25 C., a ratio of the compound to the mother liquid crystals was changed step by step in the order of (10% by weight:90% by weight), (5% by weight:95% by weight) and (1% by weight:99% by weight). Values of a maximum temperature, an optical anisotropy, viscosity and a dielectric anisotropy with regard to the compound were obtained by the extrapolation method.

A sample was dissolved in an acetone solution (0.1% by weight), and then 1 microliter of the solution was injected into the sample injector. A recorder used was C-R5A Chromatopac made by Shimadzu Corporation or the equivalent thereof. The resulting gas chromatogram showed a retention time of a peak and a peak area corresponding to each of the component compounds.

(18) As a solvent for diluting a sample, chloroform, hexane and so forth may also be used. The following capillary columns may also be used for separating component compounds: HP-1 (length 30 m, bore 0.32 mm, film thickness 0.25 m) made by Agilent Technologies Inc., Rtx-1 (length 30 m, bore 0.32 mm, film thickness 0.25 m) made by Restek Corporation, and BP-1 (length 30 m, bore 0.32 mm, film thickness 0.25 m) made by SGE International Pty. Ltd. A capillary column CBP1-M50-025 (length 50 m, bore 0.25 mm, film thickness 0.25 m) made by Shimadzu Corporation may also be used for the purpose of avoiding an overlap of peaks of the compounds.

(19) A ratio of liquid crystal compounds included in a composition may be calculated according to the method described below. The liquid crystal compounds can be detected by means of a gas chromatograph. A ratio of peak areas in the gas chromatogram corresponds to a ratio (in the number of moles) of the liquid crystal compounds. When the capillary columns described above were used, a correction coefficient of each of the liquid crystal compounds may be regarded as 1 (one). Accordingly, a ratio (% by weight) of the liquid crystal compounds was calculated from the ratio of the peak areas.

(20) The invention will be explained in detail by way of Examples. The invention is not limited by the Examples described below. The compounds described in Comparative Example and Examples were expressed as symbols according to definitions in Table 3 below. In Table 3, a configuration of 1,4-cyclohexylene is trans. A parenthesized number next to a symbolized compound in Examples corresponds to the number of the compound. A symbol () means any other liquid crystal compound. A ratio (percentage) of liquid crystal compounds means weight percent (% by weight) based on the total weight of the liquid crystal composition. The liquid crystal composition further includes an impurity in addition thereto. Last, the characteristic values of the composition were summarized.

(128) The compositions according to Examples 1 to 52 have a shorter response time in comparison with the composition according to Comparative Example 1. Thus, the liquid crystal composition of the invention is so much superior in characteristics to the composition shown in Comparative Example 1.

(129) Industrial Applicability

(130) The invention provides a liquid crystal composition satisfying at least one of characteristics such as a high maximum temperature of a nematic phase, a low minimum temperature of the nematic phase, a small viscosity, a suitable optical anisotropy, a large negative dielectric anisotropy, a large specific resistance, a high stability to ultraviolet light and a high stability to heat, or having a suitable balance regarding at least two of the characteristics. A liquid crystal display device containing such a liquid crystal composition is applied as an AM device having a short response time, a large voltage holding ratio, a large contrast ratio, a long service life and so forth, and thus can be used for a liquid crystal projector, a liquid crystal television and so forth.
