The invention provides a liquid crystal composition with a positive dielectric anisotropy. The liquid crystal composition comprises one or more compounds selected from a general formula I, a general formula II, a general formula III and a group of combinations of the general formulas as first components, and one or more compounds selected from a general formula IV, a general formula V, a general formula VI and a group of combinations of the general formulas as second components, wherein the dielectric anisotropies of the first components are positive, and the dielectric anisotropies of the second components are negative.

Description
Technical field
The present invention relates to a kind of liquid-crystal composition, in particular to a kind of electrooptics object purposes liquid-crystal composition and comprise the liquid-crystal display of this liquid-crystal composition, the indicating meter and the in-plane that particularly comprise this liquid-crystal composition active array addressing change the indicating meter of (IPS) type.
Background technology
Liquid-crystal display (Liquid Crystal Display, LCD) obtains develop rapidly because little, lightweight, the low in energy consumption and display quality of its volume is excellent, obtains especially and apply widely in portable electronic information product.Along with the increase of the LCD screen size for portable computer, office application, Video Applications, can be used in large screen display to make liquid-crystal display and finally instead of indicating meter (the Cathode Ray Tube of cathode tube, CRT), Railway Project is also had to need to solve.As improved viewing angle characteristic and improving response speed etc.The visual angle of LCD is narrow refer to leave observe perpendicular to liquid crystal cell normal direction time, contrast gradient obviously declines, and for gray scale and colored display, the phenomenon of gray scale and colour reversal also can occur when visual angle is large, had a strong impact on the display quality of LCD.Viewing angle problem becomes the large obstacle that LCD substitutes CRT technology.
The viewing angle problem of LCD is determined by the principle of work of liquid crystal itself.Liquid crystal molecule is bar-shaped, and different molecular arrangement modes correspond to different optical anisotropies.Incident light and liquid crystal molecule angle less, degree of birefringence is less; Otherwise degree of birefringence is larger.Departing from display screen normal direction, incide the light of liquid crystal cell with different angles different from the angle of liquid crystal molecule director, and under therefore causing different visual angles, effective path difference △ n*d is different.And the optimal light path difference of liquid crystal cell designs according to the normal direction perpendicular to box, for the light of oblique incidence, minimum transmittance increases with the increase of angle, and contrast gradient will decline.When angle is enough large, even there will be the phenomenon of contrast inversion.
At present, the method that proposed a variety of solution viewing angle problem is as optical compensation curved (Optically Compensated Bend, OCB) pattern, in-plane switching mode (In-Plane Switching, IPS), fringe field switching mode (Free Fall Sensor, and multidomain homeoptropic pattern (Multi-Domain Vertical Alignment, MVA) etc. FFS).
They have respective relative merits, multidomain homeoptropic pattern has the feature of high-contrast and response fast, but it needs a biaxial compensation film and two ellipsoidal polarizing plates, therefore cost is higher, the very difficult voltage of alternating current of ocb mode keeps stability contorting, to R, G, B tri-kinds of monochromatic transmitances are different, in addition when field-free, molecule in liquid crystal cell arranges by the direction being parallel to substrate, in order to realize bend alignment, need add several seconds voltage on box carries out preset, then this arrangement mode can be maintained at lower voltages, this makes troubles to use.In-plane switching mode only needs linear polarizer and does not need compensate film, and just its response speed is too slow, can not show the picture of rapid movement.Making due to IPS pattern and FFS mode is simple and have very wide visual angle, and they have become to improve viewing angle characteristic and the most attractive way realizing large-area displays.
The beginning of the seventies in last century, experimental research is carried out to basic electro-optical characteristic evenly distributed and aligned twisted, nematic liquid crystal IPS pattern, be characterized in that pair of electrodes makes on the same substrate, and another substrate there is no electrode, controlling the arrangement of liquid crystal molecule by being added in this interelectrode transverse electric field, this pattern therefore also can be claimed to be transverse field pattern.Nematic liquid crystal molecules uniform parallel arrangement between two substrates in IPS pattern, the orthogonal placement of two polaroids.IPS pattern is when not added electric field, and incident light is blocked by two orthogonal polaroids and in dark-state, during added electric field, liquid crystal molecule rotates and causes delay, so there is light to spill from two orthogonal polaroids, its displaying principle as shown in Figure 1.
IPS pattern can use positivity liquid crystal or negative liquid crystal, because transmittance saturation voltage reduces with the increase of the absolute value of △ ε, so the transmittance saturation voltage of positivity liquid crystal is lower than negative liquid crystal, and response speed is faster, but negative liquid crystal is more quite a lot of than the transmittance of positivity liquid crystal.Reason is illustrated in fig. 2 shown below, mainly caused by positive and negative liquid crystal rotation difference under the electric field.
Samsung is disclosed a kind of scheme of positive negative liquid crystal mixture at the patent CN101270287A Zeng Jin that on February 20th, 2008 applies for, but just mentions add positivity component in negative liquid crystal, and liquid crystal entirety is still negativity.Chisso Corp to apply for a patent in JP2002156619A also Zeng Jin on November 21st, 2000 and is disclosed a kind of experimental program of positive and negative liquid crystal mixture, and above two schemes all do not mention in positivity liquid crystal the lifting effect of a small amount of negative liquid crystal monomer to the transmitance of IPS liquid-crystal display of adulterating in detail.
Summary of the invention
The object of this invention is to provide a kind of liquid-crystal composition be applied in IPS pattern, one or more negative liquid crystal monomers are entrained in the IPS liquid crystal of positive dielectric anisotropic by described liquid-crystal composition, wonderful discovery, by this kind of doping pattern, can when maintaining △ ε and being constant, increase ε ∥ and the ε ⊥ of liquid crystal, wherein △ ε=ε ∥-ε ⊥, △ ε is dielectric anisotropy, ε ∥ is the specific inductivity be parallel on molecular axis direction, ε ⊥ is perpendicular to the specific inductivity on molecular axis direction, the liquid crystal of △ ε >0 is called positivity liquid crystal, the liquid crystal of △ ε <0 is called negative liquid crystal.
Transmitance formula transmittance(transmitance according to IPS pattern) ∝ △ ε/ε ⊥ (" ∝ " expression " reverse proportionality " relation).By above-mentioned negative liquid crystal monomer is adulterated in the IPS liquid crystal of positive dielectric anisotropic, the liquid-crystal composition obtained can be made in the fast-response keeping positivity IPS liquid crystal, while the advantages such as low driving voltage, higher clearing point, lower rotary viscosity, suitable optical anisotropy and suitable dielectric anisotropy, also greatly improve the transmitance of liquid-crystal display, can 5 ~ 20% be improved with the IPS mesomorphic phase of existing positive dielectric anisotropic than transmitance.
