Description

Liquid-crystal composition and application thereof
Technical field
The present invention relates to a kind of liquid-crystal composition, particularly relate to that a kind of low temperature intersolubility is good, dielectric anisotropy big, viscous Spend the liquid-crystal composition low, resistivity is high and application in a liquid crystal display thereof.
Background technology
From the point of view of liquid crystal display cells, be divided into PC(phase change, phase transformation according to the display pattern of liquid crystal), TN (twist nematic, twisted-nematic), STN (super twisted nematic, super twisted nematic), ECB (electrically controlled birefringence, electrically conerolled birefringence), OCB(optically compensated Bend, optical compensation curved), IPS(in-plane switching, coplanar transformation), VA(vertical alignment, hang down Straight orientation) etc. type.Liquid crystal display cells is divided into according to the type of light source and utilizes the reflection-type of nature light, utilizes passing through of backlight Type and utilize nature light and the semi-transmission type of two kinds of light sources of backlight.
Liquid crystal material must have good low temperature intersolubility and heat endurance.Additionally, liquid crystal material should have low viscous Degree and short response time, low threshold voltage and high-contrast.In order to obtain the liquid crystal display cells with superperformance, and improve Liquid-crystal composition each to performance indications.We are by a kind of for a kind of performance correspondence liquid crystal display cells of liquid-crystal composition The association of performance, is summarized in table 1 below.The each to performance of composition is further illustrated according to commercially available liquid crystal display cells Index.Nematic temperature range is associated with the operating temperature range of element.Nematic ceiling temperature is preferably more than Equal to 70 DEG C, and nematic lower limit temperature is preferably less than equal to-10 DEG C.During the response of the viscosity of composition and element Between be associated.Short in order to show the response time of animation, preferably element in the component.Therefore, preferably composition Viscosity is little, and when preferably temperature is low, the viscosity of composition is little.
Table 1. composition and the general characteristic of liquid crystal display cells
NO. The general characteristic of composition The general characteristic of liquid crystal display cells
1 Nematic temperature range is wide Spendable temperature range is wide
2 Viscosity is little Response time is short
3 Optical anisotropy is suitable Contrast is big
4 Plus or minus dielectric constant anisotropy is big Critical voltage is low, consumes electric power little, and contrast is big
5 Resistivity is big Voltage retention is big, and contrast is big
6 To ultraviolet and thermally-stabilised Life-span is long
The optical anisotropy of composition is associated with the contrast of element.In order to make the contrast ratio of liquid crystal display cells Maximize, can (Δ n) be set as with the product value (Δ n*d) of the thickness (d) of liquid crystal layer by the optical anisotropy of liquid-crystal composition The mode of fixed value is designed.Suitable product value depends on the kind of operating mode.As TN pattern element appropriate value about It it is 0.45 μm.During this situation, for the element that thickness of liquid crystal layer is less, the combination that preferably optical anisotropy is big Thing.
The big dielectric anisotropy of composition contributes to making element to have a low critical voltage, little power consumption and big Contrast.Therefore, the biggest dielectric anisotropy.The resistivity of composition contributes to greatly making element have big electricity Pressure conservation rate and big contrast.Therefore, preferably it is not only at room temperature in the starting stage and the most also has The composition of bigger resistivity.Preferably long-time use after the most at room temperature and also the most also there is bigger electricity The composition of resistance rate.Composition is relevant to the stability of ultraviolet and heat and the life-span of liquid crystal display cells.Aforementioned stable is high Time, the life-span of this element is long.This kind of characteristic is for liquid crystal projection apparatus, for the liquid crystal display cells used in LCD TV etc. It is preferable.
Comparatively ideal liquid crystal display cells be have that spendable temperature range is wide, the response time is short, contrast is big, critical The characteristics such as voltage is low, voltage retention is big, life-span length, preferably the response time is even shorter than 1 millisecond.Therefore, composition The most nematic ceiling temperature of characteristic lower limit temperature high, nematic low, viscosity is little, optical anisotropy is big, Dielectric constant anisotropy is big, resistivity is big, high to the stability of ultraviolet, high to the stability of heat.
Single liquid-crystal compounds is generally difficult to play its characteristic, generally it is mixed with other plurality of liquid crystals compounds and joins Make composition.In available liquid crystal composition, it is possible to obtain preferably characteristic, but this species compound optical anisotropy Big not, dielectric anisotropy is big not, helps little to being mixed into composition big for Δ n and Δ ε, thus is unfavorable for being used in little In the product that box is thick, directly result in response speed the fastest.
It is an object of the invention to provide a kind of liquid-crystal composition, its have nematic ceiling temperature high, nematic under Limit temperature low (i.e. transition temperature range width)；Viscosity is low；Optical anisotropy is big；Dielectric anisotropy is big；Steady to ultraviolet Qualitative height；At least one characteristic in the characteristics such as low temperature storage stability is high.Other objects of the present invention are to provide a kind of liquid crystal Display element, its be have that optical anisotropy is big, dielectric anisotropy big, combination to characteristics such as the stability of ultraviolet are high Thing, and make the spies such as the liquid crystal display cells response time is short, irrigation crystal speed is fast, voltage retention is big, contrast is big, life-span length Property.
Summary of the invention
It is an object of the invention to provide a kind of liquid-crystal composition, it possesses, and nematic temperature range width, viscosity is low, optics The characteristics such as anisotropy is big, dielectric anisotropy is big, low temperature storage stability is high, comprise the liquid crystal display unit of this liquid-crystal composition Part has that fast response time, irrigation crystal speed is fast, low temperature storage stability advantages of higher.
