Description
Technical Field
The present invention relates to a liquid crystal composition and a liquid crystal display device thereof, and more particularly, to a liquid crystal composition having appropriate optical anisotropy, appropriate dielectric anisotropy, a high clearing point, and a low rotational viscosity, and a liquid crystal display device including the same.
Background
Liquid crystal display devices are classified into types such as PC (phase change), TN (twisted nematic), STN (super twisted nematic), ECB (electrically controlled birefringence), OCB (optically compensated bend), IPS (in-plane switching), VA (vertical alignment), and the like according to a display mode of liquid crystal. The device is classified into a PM (passive matrix) type and an AM (active matrix) type according to a driving method of the device. PM is classified into static (static) and multiplex (multiplex) types. AM is classified into a TFT (thin film transistor), an MIM (metal insulator metal), and the like. The types of TFTs are amorphous silicon (amorphous silicon) and polycrystalline silicon (polysilicon). The latter is classified into a high temperature type and a low temperature type according to a manufacturing process. Liquid crystal display elements are classified into a reflection type using natural light, a transmission type using backlight, and a semi-transmission type using both light sources of natural light and backlight, depending on the type of light source.
TABLE 1 general characteristics of the compositions with AM elements
| NO. | General characteristics of the composition | General characteristics of AM elements |
| 1 | Wide temperature range of nematic phase | Wide temperature range |
| 2 | Low viscosity | Short response time |
| 3 | Appropriate optical anisotropy | High contrast |
| 4 | Large positive or negative dielectric constant anisotropy | Low critical voltage, low power consumption and high contrast |
| 5 | High resistivity | High voltage holding ratio and high contrast |
| 6 | UV and heat stabilization | Long service life |
The liquid crystal material is required to have suitably high dielectric anisotropy, optical anisotropy and good low-temperature stabilityAnd (5) performing qualitative determination. In addition, the liquid crystal material should also have a low rotational viscosity and short response time, a low threshold voltage and a high contrast. The performance indexes of the composition are further described based on commercially available liquid crystal display elements. The temperature range of the nematic phase is correlated with the operating temperature range of the element, and the lower the melting point, the higher the clearing point, the wider the temperature range of the nematic phase of the liquid crystal. The upper limit temperature (i.e., the temperature raised to the clearing point, Cp) of the nematic phase is preferably 70 ℃ or higher, and the lower limit temperature (i.e., the temperature lowered to the melting point, t) of the nematic phase is preferably 70 ℃ or higher-40℃) Preferably at most-10 ℃. The rotational viscosity of the composition correlates to the response time of the element. In order to display animation in the element, it is preferable that the response time of the element is short. Therefore, it is preferable that the rotational viscosity of the composition is small, and it is more preferable that the rotational viscosity of the composition is small at a low temperature.
The temperature range of the nematic phase is related to the temperature range in which the liquid crystal display device is used, and the liquid crystal display device containing the liquid crystal composition having a wide temperature range of the nematic phase can be used as a liquid crystal display device in a wider range of temperature.
A liquid crystal display element containing a liquid crystal composition having a large absolute value of dielectric anisotropy can reduce the base voltage value, reduce the driving voltage, and further reduce the power consumption.
A liquid crystal display element containing a liquid crystal composition having a low rotational viscosity can shorten the response time. When the response time of the liquid crystal display element is short, the liquid crystal display element is suitable for animation display. In addition, when the liquid crystal composition is injected into the cell of the liquid crystal display device, the injection time can be shortened, and the workability can be improved.
In the existing liquid crystal composition, better characteristics can be obtained, but the nematic phase temperature range of the compound is not wide enough, the clearing point is lower, the rotational viscosity is higher, the optical anisotropy is not large enough, the dielectric anisotropy is not large enough, the low-temperature stability is poor, the voltage holding ratio is low, the compound does not help much to be mixed into a composition with larger optical anisotropy, proper dielectric anisotropy, better stability and better contrast ratio, and the adverse consequences such as low contrast ratio, slow response speed and the like of a liquid crystal display element containing the compound are directly caused
Therefore, there is a need for a liquid crystal composition having a wide nematic phase temperature range; a higher clearing point; low rotational viscosity; appropriate optical anisotropy; appropriate dielectric anisotropy; good low-temperature stability, high charge retention rate, and the like.
