Definitions

  • the present invention relates to a liquid crystal compound for long-term storage and a storage method.
  • Liquid crystal display elements have come to be widely used from consumer applications such as LCD TVs, mobile phones and personal computers to industrial applications. These products have a relatively long product life of several years to several tens of years, and operate normally during this period. Therefore, liquid crystal materials used for these products are required to have high stability.
  • a specific stability index of a liquid crystal material is a specific resistance value. In order for the liquid crystal display element to operate normally, the specific resistance value of the liquid crystal material used for the liquid crystal display element must be sufficiently high, and deterioration over time must be suppressed.
  • liquid crystal materials such as high-speed response and high contrast. These physical properties cannot be achieved by a single compound, and a plurality of liquid crystal compounds are mixed to meet the demand as a liquid crystal composition. At that time, it is important that each liquid crystal compound is accurately weighed and its mixing ratio is adjusted to the target value. This is because if an error occurs in the mixing ratio, the physical properties change, and a liquid crystal composition that satisfies the requirements cannot be prepared.
  • each liquid crystal compound constituting the liquid crystal composition must also have a high specific resistance value.
  • it has been conventionally studied to increase the purity of the compound see Patent Document 4. Therefore, there has been no application of a directional method in which another substance is added to a liquid crystal compound that requires a very high purity to lower the purity. Further, it is considered that when an additive is added to a compound, there is a demerit that it is difficult to control the amount of the additive present together with the compound when preparing a composition by preparing a plurality of compounds.
  • the storage stability of the liquid crystal compound in the state of one kind of compound, which is a pre-stage adjusted to the liquid crystal composition is also important.
  • the liquid crystal compound is usually subjected to transportation and long-term storage after production, and therefore it may be placed under high temperature conditions. Therefore, some liquid crystal compounds have a problem that they deteriorate during storage of the liquid crystal compounds.
  • liquid crystal display devices have been required to have higher stability, but no specific means for storing them for a long period of time while maintaining a high level of purity of the compound has been reported.
  • the problem to be solved by the present invention is to provide a composition that can be stored for a long period of time while maintaining a high level of purity of substantially one kind of liquid crystal compound, and substantially one kind of liquid crystal compound. Is to be stored while maintaining a high level of purity.
  • the inventors of the present invention have added an additive for preventing the liquid crystal compound from being altered to form a composition, which is contained in an airtight container as described above.
  • the present inventors have found that the problem can be solved and have completed the present invention.
  • the present invention provides a composition that contains substantially one type of liquid crystal compound and an additive that prevents alteration of the liquid crystal compound and is contained in an airtight container.
  • the liquid crystal composition of the present invention can store one type of liquid crystal compound for a long period of time while maintaining a high level of purity. Therefore, by preparing a liquid crystal composition in which a plurality of liquid crystal compounds are mixed using the liquid crystal composition of the present invention, a liquid crystal for producing a liquid crystal display element having higher stability and usable for a long period of time. A composition can be obtained.
  • substantially one type of liquid crystal compound is composed of one type of liquid crystal compound, but in one type of liquid crystal compound, impurities inevitably mixed when the liquid crystal compound is produced. It may mean that it may contain.
  • liquid crystal compounds are manufactured through a purification process, but it is difficult to completely eliminate impurities even after the purification process. Contains a little. Thus, even if it is manufactured as one type of liquid crystal compound, it inevitably contains impurities, so it is referred to as “substantially one type of liquid crystal compound”.

  • any one or more of R I1 and R I2 preferably have a —CH ⁇ CH— or —C ⁇ C— structure in the group. Since a compound having such a structure is easily deteriorated and deteriorated, the effect of improving stability by storing it together with an additive for preventing deterioration of the liquid crystal compound is great.
  • the general formula (I) is a compound exhibiting liquid crystallinity near room temperature.
  • a compound that exhibits liquid crystallinity near room temperature tends to deteriorate and deteriorate compared to a compound that does not exhibit liquid crystallinity near room temperature, so stability by storing it with an additive that prevents the liquid crystal compound from deteriorating.
