Description

液晶組成物及使用其之液晶顯示元件 Liquid crystal composition and liquid crystal display element using same

本發明係關於一種作為電氣光學之液晶顯示材料有用的介電各向導性(△ε)表示為正值之向列型液晶組成物。 The present invention relates to a nematic liquid crystal composition having dielectric constant (Δε) which is useful as an electro-optical liquid crystal display material and which has a positive value.

液晶顯示元件被用於以時鐘、計算器為代表之各種測定機器、汽車用面板、文字處理機、電子記事本、印表機、電腦、電視、時鐘、廣告顯示板等。作為液晶顯示方式，其代表有以使用TN(扭轉向列)型、STN(超扭轉向列)型、TFT(薄膜電晶體)之垂直定向為特徵的VA型或以水平定向為特徵之IPS(橫向電場效應)型/FFS型等。用於該等液晶顯示元件所使用之液晶組成物，相對於水、空氣、熱、光等之外部因素為穩定，又，謀求以室溫為中心，而儘可能以寬廣溫度範圍表示液晶相、低黏性，且驅動電壓低。進而液晶組成物，為了相對於各別顯示元件配合最適當的介電各向導性(△ε)或/及將折射率異向性(△n)等成為最適當的值，而由數種至數十種之化合物來構成。 The liquid crystal display element is used for various measuring machines represented by clocks and calculators, automobile panels, word processors, electronic notebooks, printers, computers, televisions, clocks, advertisement display boards, and the like. As the liquid crystal display mode, it is represented by a VA type characterized by a vertical orientation using a TN (twisted nematic) type, an STN (super twisted nematic) type, a TFT (thin film transistor), or an IPS characterized by horizontal orientation ( Transverse electric field effect) type / FFS type, etc. The liquid crystal composition used for the liquid crystal display elements is stable with respect to external factors such as water, air, heat, light, etc., and is intended to represent the liquid crystal phase in a wide temperature range as much as possible centering on the room temperature. Low viscosity and low drive voltage. Further, in order to match the optimum dielectric conductivity (Δε) or/and the refractive index anisotropy (Δn) to the respective display elements, the liquid crystal composition is optimally used. Dozens of compounds are formed.

垂直定向型顯示器係使用△ε為負之液晶組成物，TN型、STN型或IPS型等水平定向型顯示器係使用△ε為正之液晶組成物。近年，亦報告有在無施加電壓時，使△ε為正之液晶組成物定向為垂直，以施加IPS型/FFS型電場來顯示之驅動方式，而△ε為正之液晶組成物的必要性更進一步提升。另一方面，於全部的驅動方式中，被要求有低電壓驅動、 高速應答、寬廣動作溫度範圍。即，要求有△ε為正且絕對值大、黏度(η)小、向列相-等向性液體相轉移溫度(Tni)高。又，必須根據△n與單元間隙(d)之積即△n×d之設定，配合單元間隙而將液晶組成物之△n調整於適當的範圍。此外，將液晶顯示元件應用於電視等時，由於重視高速應答性，故要求γ1小之液晶組成物。 The vertical alignment type display uses a liquid crystal composition having a negative Δ ε, and a horizontal directional display such as a TN type, an STN type or an IPS type uses a liquid crystal composition having a positive Δ ε. In recent years, it has been reported that, when no voltage is applied, the liquid crystal composition having a positive Δε is oriented perpendicularly, and an IPS type/FFS type electric field is applied to display the driving mode, and the necessity of Δε being a positive liquid crystal composition is further advanced. Upgrade. On the other hand, in all driving methods, low voltage driving, high speed response, and wide operating temperature range are required. That is, it is required that Δε is positive and the absolute value is large, the viscosity (η) is small, and the nematic phase-isotropic liquid phase transition temperature (T ni ) is high. Further, it is necessary to adjust the Δn of the liquid crystal composition to an appropriate range in accordance with the setting of Δn × d which is the product of Δn and the cell gap (d), in accordance with the cell gap. Further, when a liquid crystal display element is applied to a television or the like, since high-speed responsiveness is emphasized, a liquid crystal composition having a small γ 1 is required.

揭示有作為液晶組成物之構成成分，使用△ε為正之液晶化合物即式(A-1)或式(A-2)所示之化合物的液晶組成物(專利文獻1至專利文獻4)，而該等之液晶組成物難以達到充分地實現低黏性 A liquid crystal composition (Patent Document 1 to Patent Document 4) of a compound represented by Formula (A-1) or Formula (A-2) in which a liquid crystal compound having a positive Δ ε is used as a constituent component of a liquid crystal composition is disclosed. These liquid crystal compositions are difficult to achieve sufficient low viscosity

另一方面，揭示有一種關於為了改善液晶顯示器的性能，將具有氟原子或三氟甲氧基作為極性基者以外之具有各種基之化合物及含有其之組成物的發明(專利文獻5至專利文獻18)。然而，同樣地該等之液晶組成物仍無法說是必定能達到充分地實現低黏性。 On the other hand, there is disclosed an invention having a compound having various groups other than a fluorine atom or a trifluoromethoxy group as a polar group and a composition containing the same in order to improve the performance of the liquid crystal display (Patent Documents 5 to 5) Literature 18). However, it is still impossible to say that such liquid crystal compositions are capable of achieving a sufficiently low viscosity.

為了高速應答之低黏性化外，於液晶組成物中，為了液晶顯示元件之高壽命化，而要求有即使長時間使用品質或經時變化小者。尤其是，揭示有一種關於一般低分子有機化合物之液晶材料，由於對於紫外線有安定性不強等問題，為了解決該問題，於具有嘧啶環之化合物含有添加劑之液晶組成物(專利文獻19)或於組合有特定化合物之介電各向導性為 負之液晶組成物含有添加劑之液晶組成物(專利文獻20)的發明。 In addition to the low viscosity of the high-speed response, in the liquid crystal composition, in order to increase the life of the liquid crystal display element, it is required to have a small quality or a small change over time. In particular, it is disclosed that a liquid crystal material of a general low molecular organic compound has a problem that the stability of the ultraviolet light is not strong, and the like, in order to solve the problem, a liquid crystal composition containing an additive in a compound having a pyrimidine ring (Patent Document 19) or The dielectric conductivity of a combination of specific compounds is The negative liquid crystal composition contains the liquid crystal composition of the additive (Patent Document 20).

又，使用液晶組成物之液晶顯示元件，廣泛地被使用於VA(垂直定向)型或IPS(橫向電場效應)型等，且其大小亦達成50型以上之超大型尺寸之顯示元件之實用化。隨著基板尺寸的大型化，對液晶組成物之基板之注入方法亦從先前之真空注入法變成滴加注入(ODF：One Drop Fill)法，而成為注入方法的主流(參照專利文獻21)，將液晶組成物於基板滴加時之滴加痕係導致顯示品質之下降且將問題表面化，顯示不良導致液晶顯示元件之產率有惡化之情形而成為問題。又，於液晶組成物中添加抗氧化劑、光吸收劑等添加物時，亦有使其產率惡化的問題，進一步，除了滴加痕以外，亦有若液晶顯示元件長時間同樣持續顯示，則產生即使關閉顯示而其顯示仍持續顯示之被稱為殘像現象的問題。謀求作為液晶顯示元件之基本性能之對比或應答速度等特性，與難以發生殘像或滴加痕等畫質品質之信賴性兩者均備之液晶顯示元件的開發，謀求適合該等之液晶組成物之開發。 Further, a liquid crystal display element using a liquid crystal composition is widely used in a VA (Vertical Alignment) type or an IPS (Transverse Field Effect) type, and the size of the display element of a very large size of 50 or more is put into practical use. . With the increase in the size of the substrate, the method of injecting the substrate of the liquid crystal composition has been changed from the previous vacuum injection method to the one-drop filling (ODF) method, and has become the mainstream of the injection method (see Patent Document 21). When the liquid crystal composition is dropped on the substrate, the drop in the display quality causes a deterioration in display quality and causes a problem to be surfaced, which causes a problem that the yield of the liquid crystal display element is deteriorated due to poor display. Further, when an additive such as an antioxidant or a light absorbing agent is added to the liquid crystal composition, the yield is deteriorated. Further, in addition to the dropping mark, if the liquid crystal display element continues to be displayed for a long period of time, There is a problem called an afterimage phenomenon even if the display is continuously displayed even if the display is turned off. In order to develop a liquid crystal display element which is compatible with characteristics such as comparison of basic performance of a liquid crystal display element, response speed, and the like, and reliability of image quality such as afterimage or dripping, it is suitable for liquid crystal composition. Development of things.

一般而言，TN、ECB方式中之夫瑞德利克茲轉移(Freedericksz transition)的臨界電壓(Vc)係藉由式(I)表示， STN方式以式(II)表示， VA方式以式(III)表示， (式中，Vc表示夫瑞德利克茲轉移(V)、II表示圓周率、dcell表示第一基板與第二基板之間隔(μm)、dgap表示畫素電極與通用電極之間隔(μm)、dITO表示畫素電極及/或通用電極的寬度(μm)、<r1>、<r2>及<r3>表示外插長(μm)、K11表示噴射的彈性係數(N)、K22表示扭轉的彈性係數(N)、K33表示彎曲之彈性係數(N)，△ε表示介電率之各向導性)。 In general, the threshold voltage (Vc) of the Freedericksz transition in the TN and ECB modes is represented by the formula (I).

Therefore, if the interval (d) is 3 to 4 μm, the thickness tends to be thin. The product (Δn × d) is preferably 0.31 to 0.33 in the TN mode, the ECB mode, and the IPS mode. In the VA-IPS mode, when it is oriented perpendicularly to the two substrates, it is preferably 0.20 to 0.59, and particularly preferably 0.30 to 0.40.
