Description
Technical field
The present invention relates to a kind of polymerizable liquid crystal composition and the PS(polymer stabilizing containing the type liquid-crystal composition) escope.
Background technology
Liquid-crystal display (also referred to as LC indicating meter, referred to as " indicating meter " or " LCD ") the normally TN(twisted-nematic of current use) those of type.But these have the defect of striking contrast degree view angle dependency.
In addition, known so-called VA(vertical orientation) indicating meter, it has wider visual angle.The liquid crystal cell of VA indicating meter is containing liquid crystal media layer between two transparency electrodes, and wherein this liquid crystal media has negative dielectric (DC) anisotropy (Δ ε) value usually.In the switched off state, the molecule of liquid crystal layer is perpendicular to electrode surface (vertical plane ground) orientation or the orientation with inclination vertical plane.When voltage is applied on electrode, occur liquid crystal molecules parallel in electrode surface reprovision to.
In addition, known OCB(is optical compensation curved) indicating meter, it is based on birefringence effect and have so-called " bending " orientation and usually positive (DC) anisotropic liquid crystal layer.When applying voltage be, occur liquid crystal molecule perpendicular to electrode surface reprovision to.Usually containing one or more Birefringent optical phase shift films, to prevent from bending the less desirable to optical transparency of box in the dark state.OCB indicating meter has wider visual angle and shorter time of response compared with TN indicating meter.
Especially, there will be a known in IPS(face and switch) indicating meter, it contains the liquid crystal layer between two substrates, wherein only has a substrate to have electrode layer, usually has the structure of comb shape.Thus upon application of a voltage, the electric field with the remarkable component being parallel to liquid crystal layer is produced.This cause the reprovision of liquid crystal molecule in aspect to.
In addition, proposing so-called FFS(fringing field to switch) indicating meter is (especially see S.H.Jung etc., Jpn.J.Appl.Phys., the 43rd volume, No.3,2004,1028), it contains two electrodes equally in same substrate, but contrary with IPS indicating meter, they wherein only one be the form of the electrode of structurizing (comb shape), and another electrode is non-structured.Produce strong so-called vertical component and strong horizontal component thus.Both IPS indicating meter and FFS indicating meter have low contrast gradient view angle dependency.
The another kind development of the type of the above-mentioned indicating meter mentioned is so-called " PS " (" polymer stabilising ") indicating meter, and it is also known as term " PSA " (" polymer-stabilized alignment ").Wherein, will a small amount of (such as 0.3%, typically >=0.1% to≤5%, preferably reach≤scope of 3% in) polymerizable compound adds liquid crystal media, and introducing liquid crystal and afterwards with the voltage applied, usually making it be polymerized in situ in-between the electrodes by UV photopolymerization or be cross-linked.These mixtures also optionally can comprise initiator, such as, describe in US6784665.Preferably in the mixture comprising polymerizable compound, add initiator, such as, from Ciba's with the amount of 0-1%
1076.By the mesomorphic of polymerizability or liquid crystalline cpd, also referred to as " reactive mesogen " (RM), add liquid crystal compound and confirmed to be suitable for especially.Meanwhile, PSA principle is used for various traditional liquid-crystal display.Such as known PSA-VA, PSA-OCB, PSA-IPS/FFS and PS-TN indicating meter.As can be verified in testing cassete, PSA method causes the stabilization of the initial orientation of liquid crystal in box.In PSA-OCB indicating meter, therefore may realize the stabilization of warp architecture, thus make bias voltage reduce or save even completely.When PSA-VA indicating meter, reduce from " tilt angle " measured perpendicular to display surface, this has positive effect to the time of response wherein.When PSA indicating meter, the specially polymerization of reacting property mesomorphic in liquid crystal compound.Its prerequisite is that liquid crystal compound itself does not comprise any polymerizable components.
In addition, verified so-called positivity VA indicating meter is particularly advantageous embodiment.In these indicating meters, use Dielectric positive liquid crystal media.Here under no-voltage original state, the initial orientation of liquid crystal is vertical plane, is namely substantially perpendicular to substrate.Apply voltage to interdigitated electrodes, it produces the field being arranged essentially parallel to liquid crystal media layer, and this causes liquid crystal being converted into the orientation being arranged essentially parallel to substrate.Also the usual interdigitated electrodes by the type is used for IPS indicating meter.Corresponding polymer stabilising (PSA) also demonstrate that be successful in these positivity VA indicating meters.The remarkable reduction of time of response can also be realized.
Particularly for monitor and particularly TV application, and for movable application (mobile TV) and " notebook " TV(NBTV), still require the advantage that the optimization u.PSA method of the contrast gradient of time of response and liquid-crystal display and brightness (being namely also projectiveness) can provide crucial herein.Particularly when PSA-IPS, PSA-FFS and PSA-positivity VA, can realize shortening the time of response, and not have significant adverse to affect on other parameter, such as, especially, the view angle dependency that the contrast gradient of these indicating meters is favourable.
Disclose the indicating meter comprising liquid crystal compound at such as WO2009/156118A1, it has positive dielectric anisotrop.
But, when having been found that in for PSA indicating meter, from liquid crystal compound well known in the prior art and RM, still there is various defect.Preferably should not add light trigger by means of UV light to be polymerized, this may be favourable to some application.In addition, " material system " that comprise liquid crystal compound (hereinafter also referred to " liquid crystal host mixture " or also referred to as " body mixture ") and polymerizable components of selection should have minimum possible rotary viscosity and the possible electric property of the best.Here should emphasize so-called " voltage keeps ratio " (being called for short VHR or HR).Especially for PSA indicating meter, be the most important thing with the high VHR after UV rayed, because UV exposes the necessary part in normally indicating meter preparation process, but in the indicating meter certainly also exposing as " normally " and appeared at.
But, produced problem is, up to the present also the liquid crystal compound of not all and the combination of polymerizable components are all suitable for PSA indicating meter, because such as, VHR is often not enough to for TFT indicating meter, or because the stabilization of the orientation of liquid crystal compound can not be satisfactory.
Especially, expect to have for the available type material of PSA indicating meter, it has significantly less shortcoming for practical application.
Therefore, exist to PSA indicating meter, particularly IPS and FFS type, with for the liquid crystal media of this class display and the great demand of polymerizable compound, they do not demonstrate above-mentioned defect or only not half demonstrate these defects, and there is the performance of improvement.Especially, there is the great demand for PSA indicating meter and the material for PSA indicating meter, it promotes that high ratio resistance has large operating temperature range simultaneously, short time of response (or even at low temperatures), and low threshold voltage, a large amount of gray scale, high-contrast and wide viewing angle, and also there is high-voltage maintenance ratio (particularly also after uv exposure), and there is the time of response of improvement especially.
For more common indicating meters with especially when PSA-IPS and PSA-FFS indicating meter, it is necessary for having the novel liquid crystal medium improving performance.Especially, address-time must be improved for many type useds.Therefore, it is necessary for having relatively low viscosity, especially having the liquid crystal media of relatively low rotary viscosity.
Therefore, great demand is existed to the liquid crystal media with the character being applicable to practical application, this character such as wide nematic phase range, correspond to suitable optical anisotropy (Δ n), suitable high Δ ε and the low viscosity in particular for the time of response short especially of type of display used.
