According to the present invention, the liquid crystal composition has characteristics of suitable negative dielectric anisotropy, suitable optical anisotropy, low viscosity and wide nematic phase temperature range, and is applied for VA, MVA, PVA, PSVA, IPS or TFT mode liquid crystal display. The present invention further provides a liquid crystal display device containing the liquid crystal composition. The formulas I, II and III are defined in the instruction.
Description
Technical Field
The invention relates to a liquid crystal composition, in particular to a liquid crystal composition with proper negative dielectric anisotropy, proper optical anisotropy, lower viscosity and wider nematic phase range and application thereof in VA, MVA, PVA, PSVA, IPS or TFT mode liquid crystal displays.
Background
In the liquid crystal display device, there are classifications based on the operation mode of liquid crystal: phase change (hereinafter, abbreviated as PC), twisted nematic (hereinafter, abbreviated as TN), super twisted nematic (hereinafter, abbreviated as STN), electrically controlled birefringence (hereinafter, abbreviated as ECB), optically compensated bend (hereinafter, abbreviated as OCB), transverse electric field switching (IPS), vertical transverse (VA), and the like. The device-based driving method is classified into: passive Matrix (PM) and AM. The PM is classified into static (static) and multiplex (multiplex), and the AM is classified into a Thin Film Transistor (TFT), a metal insulator metal (MTM), and the like. The TFT is classified into amorphous silicon (amorphous silicon) and polycrystalline silicon (polycrystalline silicon). The latter may be classified into a high temperature type and a low temperature type according to manufacturing steps. The light source-based classification includes a reflection type using natural light, a transmission type using backlight (black light), and a semi-transmission type using both natural light and backlight.
Currently, Vertical Alignment (VA) displays are increasingly well known and widely used in TVs, monitors, and vehicle-mounted displays, and the liquid crystal medium used in conjunction with the VA displays needs to be specially customized. For example, the liquid-crystalline medium should have a suitable negative dielectric anisotropy, a suitable optical anisotropy, a wide nematic temperature range, a low viscosity and a fast response. For active matrix addressed liquid crystal displays, the liquid crystal medium also needs to have a high voltage holding ratio, and good optical and thermal stability. In particular, for displays used in the on-board category and other outdoor uses, it is particularly desirable to have a wide nematic temperature range and a fast response time.
However, the properties of liquid crystal media are contradictory, and the existing liquid crystal media cannot have the properties at the same time. For displays used in on-vehicle type and other outdoor applications, while securing a very wide nematic phase temperature range, appropriate negative dielectric anisotropy, appropriate optical anisotropy, as small a viscosity as possible, and good light and heat stability are required. The liquid crystal composition disclosed in chinese patent application publication No. CN101679867A has a sufficiently wide upper limit of nematic phase temperature, but has a relatively large viscosity and a relatively slow response.
It is well known that the optical retardation of the liquid crystal layer of the VA display is 1/2, and for twisted display, even if operating at the first minimum, the optical retardation of the liquid crystal layer is required to be close to one full optical wavelength, and it is seen that the cell thickness of the VA liquid crystal display is smaller than that of the twisted mode depending on the amount of optical retardation of the VA mode. In practical use, the retardation design (i.e. Δ n × d) of the VA mode lcd is usually slightly larger than the theoretical value, which is about 300nm, and the cell thickness is usually controlled to about 3-4 μm. The smaller cell thickness (3-3.5 μm) can bring faster response, but is more difficult to control in production, the yield of the manufactured liquid crystal cell is lower, and the comprehensive cost is higher. Relatively speaking, the larger box thickness (3.5-4 μm) can better control the production process, and is more beneficial to large-scale production and application. Therefore, there is an urgent need for a series of negative liquid crystal compositions with low refractive index, low negative dielectric anisotropy, low viscosity, and wide nematic phase range. The liquid crystal composition with negative dielectric anisotropy provided by the invention can meet the characteristics of low refractive index, low negative dielectric anisotropy, low viscosity and wide nematic phase range, and can be suitable for VA, MVA, PVA, PSVA, IPS or TFT mode liquid crystal displays.
