Description
Technical Field

Background
Negative liquid crystals, which were proposed at the earliest in the last 80 years, were mainly used for VA mode, which has very excellent contrast properties, but has significant viewing angle problems and response time problems. In order to solve the viewing angle problem, display technologies such as MVA, PVA, and CPA have been proposed, and the essence of these technologies is to solve the viewing angle problem with multi-domain and to achieve good effects. However, due to the increasing difficulty in the process and the problem of response time, the display industry is still plagued by the introduction of PSVA (polymer stabilized vertical alignment) technology, which uses polymers to achieve multi-domain and pretilt angle control to achieve fast response and wide viewing angle liquid crystal displays.
The polymerizable monomer exists in the liquid crystal, which can cause the voltage holding ratio of the liquid crystal to be reduced, so that corresponding procedures need to be added in the production process of the liquid crystal display, the residual polymerizable monomer is fully reacted, and the time is usually longer in order to ensure the full reaction; on one hand, the process time is prolonged, and the productivity is reduced; on the other hand, since the glass substrate needs to be exposed for a period of time after the completion of the preceding process, the surface layer of the panel is contaminated by the pollution source in the environment, which results in the degradation of the quality of the liquid crystal display.

The method for producing the liquid crystal composition of the present invention is not particularly limited, and it can be produced by mixing two or more compounds by a conventional method, such as a method of mixing the different components at a high temperature and dissolving each other, wherein the liquid crystal composition is dissolved and mixed in a solvent for the compounds, and then the solvent is distilled off under reduced pressure; alternatively, the liquid crystal composition of the present invention can be prepared by a conventional method, for example, by dissolving the component having a smaller content in the main component having a larger content at a higher temperature, or by dissolving each of the components in an organic solvent, for example, acetone, chloroform or methanol, and then mixing the solutions to remove the solvent.
The liquid crystal composition provided by the invention has a fast reaction speed, can shorten the time for polymerizing the polymerizable compound, greatly shortens the time required by the polymerization process of the liquid crystal display, improves the yield of the liquid crystal display, shortens the exposure time of the liquid crystal display in the environment and improves the quality and performance of the liquid crystal display. Therefore, the liquid crystal composition provided by the invention is suitable for PSVA and SAVA display mode liquid crystal display devices; the liquid crystal display is particularly suitable for PSVA liquid crystal display devices.
The method for preparing the liquid crystal device by adopting the liquid crystal composition provided by the invention specifically comprises the following steps: a liquid crystal composition containing a polymerizable compound is poured into a liquid crystal panel, and then polymerized by irradiation of UV light, and a voltage is continuously applied during the irradiation. The polymerizable compound in the liquid crystal composition is polymerized under the irradiation of UV light, so that the liquid crystal is promoted to form stable alignment.
The polymerizable monomer is generally in a two-biphenyl or terphenyl structure, and polymerizable groups are connected at two ends of the polymerizable monomer, and researches show that the polymerizable monomer in the terphenyl structure is easy to generate a chromatography phenomenon when flowing along with a liquid crystal composition on the surface of an alignment layer, so that the polymerizable monomer is not uniformly distributed, liquid crystal molecules are not uniformly arranged after polymerization, and the brightness of a liquid crystal display is not uniform, so the polymerizable monomer in the two-biphenyl structure is generally adopted, the absorption of the two-biphenyl structure to light is about 310nm, and the step of forming a pretilt angle by polymerization is generally irradiated by 365nm UV light, so that the absorption of the polymerizable monomer to the UV light is very limited, and the polymerization. The researchers of the invention find that when the terphenyl structure shown in the general formula IV is added into the liquid crystal composition, the absorption wavelength of the terphenyl is near 365nm, so that the UV light energy can be rapidly absorbed and then transmitted to the polymerizable monomer, and the polymerization reaction of the polymerizable monomer is accelerated. The energy transfer model is shown in fig. 1.
