Description

【0001】
【発明の属する技術分野】
本発明は、ネマチック液晶組成物に関し、さらに詳しくは、アクティブマトリックスLCD表示方式を用いた液晶表示素子に好適に使用される液晶組成物、およびこの液晶組成物を用いた液晶表示素子に関する。
【0002】
【従来の技術】
液晶表示素子(LCD)は、CRT(ブラウン管方式ディスプレイ)に比べて、低消費電力、小型化、軽量化が可能であるために、ツイステッドネマティック(TN)方式、スーパーツイステッドネマティック(STN)方式、薄膜トランジスター(TFT)方式等の種々のLCDが実用化されてきた。その中で薄膜トランジスター(TFT)方式等のアクティブマトリックスLCD(AM−LCD)はカラー化、高精細化が進みフラットパネルディスプレイとして広く普及している。また、近年、次世代の有望な高速応答表示モードとして、OCB(Optically Compensated Birefringence)方式のLCDが脚光を浴びてきている。
【0003】
AM−LCD用液晶組成物に求められる一般的な特性には、
(1)LCDの高コントラストを維持するために、液晶組成物を注入したセルの電圧保持率(V.H.R)が高いこと、
(2)ネマティック液晶相を示す温度範囲が広いこと、
(3)セル厚に応じて、適当な屈折率異方性(Δn)を取り得ること、
(4)駆動回路に応じて、適当なしきい値電圧を取り得ること、
がある。セル厚が小さい、特に、好ましくは3μm以下のセル厚のAM−LCDに用いられる液晶材料には、上記(3)項のΔnの値が大きいことが要求される。
【0004】
AM−LCDの動作方式では、上下の電極基盤間における液晶分子の配向を約90°ツイストさせたTN表示方式が広く採用されている。このTN表示方式においては、電圧を印加しない状態での干渉による液晶セルの着色を防ぎ、かつ、最適なコントラストを得るために、屈折率異方性(Δn)とセル厚(d)μmの積(Δn・d)をある一定の値(例えばΔn・d=〜0.5μm等)に設定する必要がある。このような制限のもとで現在実用化されているTFT用液晶組成物のΔnはファ−ストミニマム条件で0.07〜0.15程度、特に0.08〜0.13が主体になっている。E.Jakemanなど(Phys. Lett., A, 39(1972)69)によって提唱されているように、応答時間(以下τと略記することがある)は液晶材料の粘度(以下ηと略記することがある)に比例し、かつ、セル厚dの2乗に比例する。Δnの大きな液晶組成物を使用すればセル厚dの値を小さくできるため、τは著しく低下する。このように液晶表示素子に用いられる液晶組成物は、適当に大きなΔnを有することが非常に有益である。
【0005】
また、小型軽量で携帯可能なノート型パーソナルコンピューター等が開発され、さらにLCDの用途が広がってきている。携帯用途のLCDは、駆動電源によって特性の制約を受ける。長時間使用するためには消費電力を小さくする必要があるので、駆動電力の低電圧化、すなわち、しきい値電圧の小さい液晶組成物が要求される。要求される液晶材料のしきい値電圧の値は、実用化されている5V駆動装置で2.0V程度、4V駆動装置で1.6V程度である。最近ではさらに低電圧化を要求されるようになり、しきい値電圧が1.5V以下の液晶組成物も探求されている。さらには、LCDの小型化に伴って、屋外での使用を目的とした装置の開発も検討されている。屋外の使用に耐えうるには、使用環境の温度範囲を超えた領域にわたってネマティック相を呈することが要求される。このような観点から現在実用化されているTFT用液晶組成物は、そのネマティック−アイソトロピック相転移温度(透明点:TNI)が60℃以上、スメクティック−ネマティック相転移温度(TSN)が−20℃以下のものが主体である。
【0006】
このような背景に伴って、特表平5−500679号公報には、新規な化合物およびその化合物を用いた液晶組成物が開示されている。しかし、この組成物の中にはΔnの値が大きいものもあるが、同時にしきい値電圧が大きすぎ、実用化されている駆動電圧、特に低電圧駆動には適していない。このように液晶組成物は種々の目的に応じて鋭意検討されてはいるものの、常に新規な改良を要求されているのが現状である。
【0007】
【発明が解決しようとする課題】
本発明者らは、これら従来の課題を解決すべく、種々の液晶化合物を用いた組成物について鋭意検討した。その結果、特に高Δnを必要とするアクティブ・マトリックス方式の液晶表示素子(AM−LCD表示素子)にも好適に使用される組成物を見いだし、本発明を完成した。以上の記述から明らかなように、本発明の目的は、AM−LCD表示素子に求められる一般的な特性を満たしながら、適当なしきい値電圧を持ち、特に、高温領域において電圧保持率の高い、屈折率異方性Δnの大きい液晶組成物,液晶表示素子を提供することである。

【0018】
本発明の第二成分である一般式(2−1)で表される化合物は、誘電率異方性(Δε)がおよそ6〜25の範囲にあり、透明点(Tc)がおよそ−20〜80℃の範囲、屈折率異方性(Δn)がおよそ0.12〜0.17の範囲にあり、熱および紫外線の安定性および化学的安定性に優れている。このため、本発明で一般式(2−1)で表される化合物は、特に高信頼性を要求されるTFT用液晶組成物のΔnを大きくし、また化合物の構造によってはしきい値電圧を小さくする機能を有する。
【0019】

【0020】
本発明の第三成分である一般式(3)で表される化合物は、誘電率異方性(Δε)がおよそ0であり、透明点(Tc)がおよそ220〜270℃の範囲にあり、屈折率異方性(Δn)がおよそ0.15〜0.27の範囲にあり、熱および紫外線の安定性および化学的安定性に優れている。このため、本発明で一般式(3)で表される化合物は、特に高信頼性を要求されるTFT用液晶組成物の透明点を高くする機能を有する。
【0021】
本発明は従来のAM−LCD用液晶組成物に求められる一般的な特性を満たしながら、適当なしきい値電圧を持ち、特に、高い信頼性および大きいΔnの値を持つことを特徴とする液晶組成物である。これらの特徴を発揮するために、本発明では第一成分および第二成分、または第一成分、第二成分および第三成分を含有した構成の液晶組成物になっている。

液晶組成物の特性は、以下のように測定し求めた。
ネマチック液晶相の上限温度TNIは、偏光顕微鏡を用いて、昇温過程において、ネマチック相から等方性液体相に変化するとき状態を観察して、その温度を測定することにより求めた。ネマチック液晶相の下限温度Tは、0℃、−10℃、−20℃、および−30℃のそれぞれの温度に保ったフリーザー中に、液晶組成物を30日間放置し、結晶もしくはスメクチック相が出現するフリーザーの温度で判断した。例えば、一つの液晶組成物について、−20℃でネマチック状態をとり、−30℃で結晶化またはスメクチック状態となった場合には、その液晶組成物のTは、<−20℃と表現した。
【0031】
屈折率異方性Δnは、589nmの波長を有する光源ランプを使用し、アッベ屈折計を用いて25℃で測定した。誘電率異方性Δεは25℃で測定した。しきい値電圧Vthは、セル厚d=約9μmの80°ツイストセルに注入し、25℃で測定したV−T曲線から求めた。
【0032】
電圧保持率VHRの測定は、日本電子機会工業会規格EIAJ ED−2521Aで規定される液晶材料および配向膜の電圧保持率測定法に準じて面積法にて行った。この測定方法は、特開平5−331464号公報にも記載されている。すなわち、試料の液晶組成物をポリイミド系配向膜を設けたセル厚6μmのTNセルに封入して作成した液晶素子に、波高値±5V、パルス幅60μsのパルス電圧を、周期30Hzの交流電圧として印可したときの、該液晶素子の電極間電圧波形を陰極線オシロスコープで観測する。単位周期における該印可電圧と周期の積(面積)に対する観測電圧の絶対値の積算値(面積)との割合を百分率で表し、電圧保持率とした。

BACKGROUND OF THE INVENTION
The present invention relates to a nematic liquid crystal composition, and more particularly to a liquid crystal composition suitably used for a liquid crystal display element using an active matrix LCD display method, and a liquid crystal display element using the liquid crystal composition.
[0002]
[Prior art]
Liquid crystal display elements (LCDs) can have lower power consumption, smaller size, and lighter weight than CRTs (CRT display), so twisted nematic (TN) method, super twisted nematic (STN) method, thin film Various LCDs such as a transistor (TFT) type have been put into practical use. Among them, an active matrix LCD (AM-LCD) such as a thin film transistor (TFT) system has been widely used as a flat panel display as colorization and high definition have progressed. In recent years, an OCB (Optically Compensated Birefringence) type LCD has been in the spotlight as a next-generation promising fast response display mode.
[0003]
General characteristics required for liquid crystal compositions for AM-LCD include:
(1) In order to maintain the high contrast of the LCD, the voltage holding ratio (VHR) of the cell into which the liquid crystal composition is injected is high.
(2) The temperature range showing the nematic liquid crystal phase is wide.
(3) An appropriate refractive index anisotropy (Δn) can be taken according to the cell thickness;
(4) An appropriate threshold voltage can be taken according to the drive circuit;
There is. A liquid crystal material used for an AM-LCD having a small cell thickness, particularly preferably a cell thickness of 3 μm or less, is required to have a large Δn value in the above item (3).
[0004]
In the operation system of AM-LCD, a TN display system in which the orientation of liquid crystal molecules between upper and lower electrode substrates is twisted by about 90 ° is widely adopted. In this TN display system, the product of refractive index anisotropy (Δn) and cell thickness (d) μm is used in order to prevent coloration of the liquid crystal cell due to interference in the state where no voltage is applied and to obtain an optimum contrast. It is necessary to set (Δn · d) to a certain value (for example, Δn · d = ˜0.5 μm). Under such restrictions, Δn of the liquid crystal composition for TFTs currently in practical use is about 0.07 to 0.15, particularly 0.08 to 0.13 under the fast minimum conditions. Yes. E. As proposed by Jakeman et al. (Phys. Lett., A, 39 (1972) 69), the response time (hereinafter sometimes abbreviated as τ) is sometimes referred to as the viscosity of liquid crystal material (hereinafter abbreviated as η). ) And proportional to the square of the cell thickness d. If a liquid crystal composition having a large Δn is used, the value of the cell thickness d can be reduced, so that τ significantly decreases. As described above, it is very useful that the liquid crystal composition used in the liquid crystal display element has an appropriately large Δn.
[0005]
In addition, notebook personal computers and the like that are small and light and portable have been developed, and the use of LCDs has further expanded. LCDs for portable use are limited in characteristics by the drive power supply. Since it is necessary to reduce power consumption in order to use it for a long time, a liquid crystal composition having a low driving power, that is, a threshold voltage is required. The required threshold voltage value of the liquid crystal material is about 2.0 V for a practical 5 V drive device and about 1.6 V for a 4 V drive device. Recently, there has been a demand for further lowering the voltage, and liquid crystal compositions having a threshold voltage of 1.5 V or less are being sought. Furthermore, with the miniaturization of LCDs, development of devices intended for outdoor use is also being studied. In order to be able to withstand outdoor use, it is required to exhibit a nematic phase over a region exceeding the temperature range of the use environment. From this point of view, a liquid crystal composition for TFT that is currently in practical use has its nematic-isotropic phase transition temperature (clearing point: T NI ) Is 60 ° C. or higher, smectic-nematic phase transition temperature (T SN ) Is -20 ° C or lower.
[0006]
With such a background, Japanese translation of PCT publication No. 5-500679 discloses a novel compound and a liquid crystal composition using the compound. However, some of these compositions have a large value of Δn, but at the same time, the threshold voltage is too large and is not suitable for a practical driving voltage, particularly low voltage driving. As described above, although the liquid crystal composition has been intensively studied according to various purposes, the current situation is that a new improvement is always required.
[0007]
[Problems to be solved by the invention]
In order to solve these conventional problems, the present inventors diligently studied compositions using various liquid crystal compounds. As a result, a composition that can be suitably used for an active matrix type liquid crystal display element (AM-LCD display element) that particularly requires a high Δn was found, and the present invention was completed. As is clear from the above description, the object of the present invention is to have an appropriate threshold voltage while satisfying general characteristics required for an AM-LCD display element, and in particular, a high voltage holding ratio in a high temperature region. It is to provide a liquid crystal composition and a liquid crystal display device having a large refractive index anisotropy Δn.

The characteristics of the liquid crystal composition were measured and determined as follows.
Maximum temperature T of nematic liquid crystal phase NI Was obtained by observing the state when changing from a nematic phase to an isotropic liquid phase in a temperature rising process using a polarizing microscope and measuring the temperature. Minimum temperature T of nematic liquid crystal phase C The liquid crystal composition was allowed to stand for 30 days in a freezer maintained at 0 ° C., −10 ° C., −20 ° C., and −30 ° C., and the temperature was determined based on the temperature of the freezer where a crystal or smectic phase appeared. . For example, when one liquid crystal composition takes a nematic state at −20 ° C. and becomes a crystallized or smectic state at −30 ° C., the T of the liquid crystal composition C Was expressed as <−20 ° C.
[0031]
The refractive index anisotropy Δn was measured at 25 ° C. using an Abbe refractometer using a light source lamp having a wavelength of 589 nm. The dielectric anisotropy Δε was measured at 25 ° C.
