Definitions
- the present invention relates to a liquid crystal composition, and more particularly to having a wide nematic phase temperature range, high optical anisotropy, suitable dielectric anisotropy, good low temperature stability, and high voltage retention.
- a liquid crystal composition having characteristics such as rate, good high temperature stability, and good ultraviolet resistance, and a liquid crystal display device including the liquid crystal composition.
- the liquid crystal display element has been developed from clocks and calculators to various electrical appliances for home use, measuring equipment, automotive panels, word processors, electronic notebooks, printers, computers, televisions, and the like.
- Typical liquid crystal display methods include a TN (twisted nematic) type, an STN type (super twisted nematic) type, a DS (dynamic light scattering) type, a GH (guest-host) type, and an IPS (planar conversion) type.
- OCB optical compensation birefringence
- ECB voltage controlled birefringence
- VA vertical alignment
- CSH color super vertical
- FLC strong dielectric liquid crystal
- examples of the driving method of the liquid crystal display device include a static driving, a multiplex driving, a simple matrix method, and an active matrix (AM) method driven by a TFT (Thin Film Transistor), a TFD (Thin Film Diode), or the like.
- a static driving a multiplex driving
- a simple matrix method a simple matrix method
- AM active matrix
- the IPS type, the ECB type, the VA type, or the CSH type have characteristics such as a liquid crystal composition exhibiting a negative value using dielectric anisotropy ⁇ ⁇ .
- the VA type display mode which is driven by AM in particular, is used for a display element (for example, a television set) requiring a high-speed response and a wide viewing angle.
- prior art liquid crystal media have relatively unfavorable optical anisotropy ([Delta]n) values, which are often significantly less than 0.11, and in some cases less than 0.10.
- SA optical anisotropy
- such small ⁇ n values are not particularly advantageous, for example, for VA type displays, since they require the use of a liquid crystal cell having a relatively large layer thickness (d) of 4 ⁇ m or more, and thus cause response time for many applications. In terms of unacceptable length. Therefore, d ⁇ n of about 0.30 ⁇ m is used in the case of untwisted orientation misalignment.
- the use of a liquid crystal cell having a very small layer thickness (d) often results in a low yield of the display. Therefore, the use of a liquid crystal medium having a higher ⁇ n value facilitates the production of the display mode and display.
- JPH08104869A discloses a liquid crystal composition comprising liquid crystal compounds II-1-3 and II-3-5 having a 2.3-difluorophenylene skeleton as follows.
- the liquid crystal composition also uses the liquid crystal compound III-2 and the liquid crystal compound (A) as a component having a ⁇ ⁇ of substantially zero.
- the composition does not reach a sufficiently low viscosity capable of satisfying a high speed.
- EP0474062A1 has also disclosed a liquid crystal composition using liquid crystal compound II-6-5, but is a liquid crystal composition in which ⁇ n is small in combination with the above liquid crystal compound (A), but since the liquid crystal composition also contains The liquid crystal composition of the liquid crystal compound III-10, which has an alkenyl group in the molecule (alkenyl compound) (see JP2006037054A), it is necessary to carry out further research in order to achieve both high ⁇ n and high reliability.
- JP2001354967A a liquid crystal composition including the liquid crystal compound II-4-5 and the liquid crystal compound III-10 has been disclosed in JP2001354967A, but it requires further high-speed response.
- JP2001354967A a liquid crystal composition containing the above alkenyl compound of III-10 is liable to cause image retention and display unevenness.
- WO2007077872A1 discloses a liquid crystal composition in which a liquid crystal compound of the formula (B) having a ⁇ of substantially zero and a liquid crystal compound II-1-3 and a liquid crystal compound II-4-5 are combined.
- the compound having a low vapor pressure is volatilized by taking an extremely low pressure, and therefore it is considered that the content of the compound having a low vapor pressure cannot be increased. Therefore, there is a problem in that the content of the liquid crystal compound represented by the formula (B) in the liquid crystal composition is limited, and the obtained liquid crystal composition exhibits a large ⁇ n but a high viscosity.
- An object of the present invention is to provide a liquid crystal composition having negative dielectric anisotropy, having appropriate dielectric anisotropy, appropriate rotational viscosity, and a high clearing point, a wide range of nematic phase temperatures, and a high A liquid crystal composition having characteristics such as optical anisotropy, good low-temperature miscibility, high voltage holding ratio, good high-temperature stability, and good ultraviolet performance.
- the liquid crystal composition of the present invention avoids the influence of exposure and/or high temperature on the liquid crystal composition, so that the liquid crystal display comprising the liquid crystal composition of the present invention can satisfy the demand for normal operation in a harsh environment. Meanwhile, the liquid crystal display including the liquid crystal composition of the present invention has a property of fast response.

Abstract
一种负介电各向异性的液晶组合物以及包括所述液晶组合物的液晶显示器件。所述液晶组合物包含：第一成分，所述第一成分包括一种或多种式Ⅰ的化合物；第二成分，所述第二成分包括两种或两种以上式Ⅱ的化合物；以及第三成分，所述第三成分包括一种或多种式Ⅲ的化合物。
Description
本发明涉及一种液晶组合物，特别涉及一种具有较宽的向列相温度范围、较高的光学各向异性、合适的介电各向异性、良好的低温稳定性、较高的电压保持率、良好的高温稳定性以及良好的抗紫外线性能等特性的液晶组合物，以及包括该液晶组合物的液晶显示器件。
液晶显示元件从时钟、计算器开始，发展到用于家庭用的各种电器设备、测定设备、汽车用面板、文字处理器、电子记事本、打印机、电脑、电视机等。作为代表性液晶显示方式，其可以举出TN(扭曲向列)型、STN型(超扭曲向列)型、DS(动态光散射)型、GH(宾主)型、IPS(平面转换)型、OCB(光学补偿双折射)型、ECB(电压控制双折射)型、VA(垂直取向)型、CSH(彩色超垂直)型或FLC(强介电性液晶)型等。此外，作为液晶显示器件的驱动方式，也可以举出静态驱动、多工驱动、单纯矩阵方式、通过TFT(薄膜晶体管)、TFD(薄膜二极管)等来驱动的有源矩阵(AM)方式。
在这些显示方式中，IPS型、ECB型、VA型或CSH型等具有使用介电各向异性Δε表现负值的液晶组合物这样的特征。在这些显示方式中，特别是通过AM驱动的VA型显示方式被用于要求高速响应且宽视角的显示元件(例如电视机等)用途。
对于大部分液晶显示器而言，现有技术的液晶介质具有相对不利的光学各向异性(Δn)值，所述的Δn值经常显著小于0.11，并且在一些情况之下小于0.10。然而，这种小的Δn值不是特别有利的，例如，对于VA型显示器，因为它们需要使用具有4μm或更大的相对较大层厚度(d)的液晶盒，并因此导致响应时间对于许多应用而言是不可接受地长。因此，在未扭转取向失排列的情况下采用约为0.30μm的d·Δn。但是，使用具有非常小的层厚度(d)的液晶盒经常导致所述显示器的产量低。因此，采用较高Δn值的液晶介质有利于所述的显示模式和显示器的制作。
作为Δε为负的液晶组合物，JPH08104869A公开了包括如下的具有2.3-二氟亚苯基骨架的液晶化合物II-1-3及II-3-5的液晶组合物。
该液晶组合物还使用液晶化合物III-2及液晶化合物(A)作为Δε大致为0的组分。但是，对于液晶电视机等的要求高速响应的液晶显示器件而言，该组合物未达到能够满足高速相应的充分低的粘性。
另一方面，EP0474062A1也已经公开了使用液晶化合物II-6-5的液晶组合物，但是是组合了上述液晶化合物(A)的Δn小的液晶组合物，但是由于该液晶组合物也是包含有下述液晶化合物III-10此类在分子内具有链烯基的化合物(链烯基化合物)的液晶组合物(参见JP2006037054A)，有必要为了兼顾高Δn和高可靠性而进行进一步的研究。
此外，JP2001354967A中已经公开了包括液晶化合物II-4-5及液晶化合物III-10的液晶组合物，但其要求更进一步的高速响应化。但是JP2001354967A中指出含有上述III-10的链烯基化合物的液晶组合物，存在容易发生图像保留、显示不均等弊病。
WO2007077872A1公开了将Δε大致为零的式(B)的液晶化合物与液晶化合物II-1-3及液晶化合物II-4-5组合而成的液晶组合物。然而，在液晶显示元件的制造工序中，向液晶单元注入液晶组合物时，会因采取极低压而导致蒸气压低的化合物挥发，因此认为无法增加蒸气压低的化合物的含量。因此，存在如下问题：该液晶组合物中式(B)所表示的液晶化合物的含量受限，所得的液晶组合物虽然表现出大的Δn但粘度明显高。
进一步，在专利文献JP2003327965A和WO2007077872A1中，也已经公开了使用具有被氟取代的三联苯结构的化合物的液晶组合物。
