與實施例6相比,對比例1液晶組合物中,不包含式Ⅰ所示化合物。使用結構相近的CPWP-3-2、CPWP-3-O2等量替代式Ⅰ所示化合物。雖然結構相近,但性能相差很大,對比例1液晶組合物介電各向異性相對於實施例6下降十分明顯,需要更大的驅動電壓才能將液晶分子完全驅動,從而消耗更多的電能。與實施例6相比,如果在相同的驅動電壓下,由於對比例1的液晶組合物無法完全驅動將降低其透過率,透過率降低便需要增加背光亮度才能獲得滿足需求的畫面亮度,從而消耗更多的電能。旋轉粘度的增加,也將使對比例1液晶組合物的回應速度變慢。Compared with Example 6, the liquid crystal composition of Comparative Example 1 does not contain the compound represented by formula I. Use equivalent amounts of CPWP-3-2 and CPWP-3-O2 with similar structures to replace the compounds shown in formula I. Although the structures are similar, the properties are quite different. The dielectric anisotropy of the liquid crystal composition of Comparative Example 1 is significantly lower than that of Example 6, and a larger driving voltage is required to fully drive the liquid crystal molecules, thereby consuming more electric energy. Compared with Example 6, if the liquid crystal composition of Comparative Example 1 cannot be fully driven at the same driving voltage, its transmittance will be reduced, and the decrease in transmittance will require increasing the brightness of the backlight to obtain a screen brightness that meets the requirements, thereby consuming More power. The increase of rotational viscosity will also slow down the response speed of the liquid crystal composition of Comparative Example 1.

與實施例6相比,對比例2液晶組合物中,不包含式Ⅱ所示化合物,使用化合物PY-2O-O4替代式Ⅱ所示化合物。組合物Δε增大的同時,ε 反而減小,進而ε /Δε減小,將導致對比例2液晶組合物透過率降低。 Compared with Example 6, the liquid crystal composition of Comparative Example 2 does not contain the compound represented by Formula II, and the compound represented by Formula II is replaced by the compound PY-2O-O4. When the composition Δε increases, ε decreases instead, and then ε /Δε decreases, which will lead to a decrease in the transmittance of the liquid crystal composition of Comparative Example 2.

與實施例1相比,對比例4液晶組合物中,式Ⅰ、式Ⅱ所示化合物的質量百分比含量之和為26%。對比例各項參數雖然與實施例相同或相近,但低溫儲存過程中出現晶析現象,具體低溫儲存情況見表15。Compared with Example 1, in the liquid crystal composition of Comparative Example 4, the sum of the mass percentages of the compounds represented by Formula I and Formula II is 26%.

The liquid crystal compositions of the examples and comparative examples were poured into the liquid crystal test box as the second set of low temperature storage experiments. The glass bottle filled with the liquid crystal composition was placed in a -20°C glove box, and the liquid crystal test box filled with the liquid crystal composition was placed in a -20°C and -30°C glove box, respectively.

從上述表15可以看出,本發明實施例液晶組合物具有更寬的向列相溫度範圍。It can be seen from the above Table 15 that the liquid crystal composition of the embodiment of the present invention has a wider temperature range of the nematic phase.

下述的表16為實施例、對比例液晶組合物信賴性測試資料。The following Table 16 is the reliability test data of the liquid crystal compositions of the examples and comparative examples.

液晶組合物在液晶顯示元件或液晶顯示器生產過程中的信賴性通過紫外老化試驗並進行VHR測試來進行,液晶組合物紫外試驗前後的VHR資料變化越小,抗紫外能力越強。因此,通過比較各個實施例、對比例在試驗前後的VHR資料的變化來判斷抗紫外能力。The reliability of the liquid crystal composition in the production process of the liquid crystal display element or liquid crystal display is carried out through the ultraviolet aging test and the VHR test. The smaller the change of the VHR data before and after the ultraviolet test of the liquid crystal composition, the stronger the anti-ultraviolet ability. Therefore, the anti-ultraviolet ability is judged by comparing the changes of the VHR data of each embodiment and comparative examples before and after the test.

液晶組合物工作過程中的信賴性可以通過背光老化試驗並進行VHR測試來進行。在長時間的背光照射下,液晶組合物將長時間處在可見光、紫外線和60~70℃的工作環境中,受到外界環境的破壞。液晶組合物背光試驗前後的VHR資料變化越小,抗外界環境破壞能力越強。因此,通過比較各個實施例、對比例在試驗前後的VHR資料的變化來判斷抗外界環境破壞能力。The reliability of the liquid crystal composition in the working process can be tested by backlight aging test and VHR test. Under long-term backlight irradiation, the liquid crystal composition will be exposed to visible light, ultraviolet rays and a working environment of 60-70°C for a long time, and will be damaged by the external environment. The smaller the change in VHR data before and after the backlight test of the liquid crystal composition, the stronger the ability to resist external environmental damage. Therefore, by comparing the changes of the VHR data of each embodiment and comparative examples before and after the test, the ability to resist damage from the external environment can be judged.

首先,在進行紫外、背光老化試驗之前,測定液晶組合物的VHR資料作為初始VHR資料,然後,對液晶組合物進行紫外、背光老化試驗,在試驗後再次測定液晶組合物的VHR資料。First, before the UV and backlight aging test, measure the VHR data of the liquid crystal composition as the initial VHR data, then carry out the UV and backlight aging test on the liquid crystal composition, and measure the VHR data of the liquid crystal composition again after the test.

紫外老化試驗:將液晶組合物灌入相應測試盒中,在波長為365nm的紫外燈下照射5000mJ能量。Ultraviolet aging test: pour the liquid crystal composition into a corresponding test box, and irradiate 5000mJ energy under an ultraviolet lamp with a wavelength of 365nm.

背光試驗:將液晶組合物灌入相應測試盒中,封口,放到光強為25000nit的背光上進行背光老化試驗,老化1000H後進行VHR測試。Backlight test: pour the liquid crystal composition into the corresponding test box, seal it, and put it on a backlight with a light intensity of 25000 nit to perform a backlight aging test. After aging for 1000 hours, perform a VHR test.

在老化試驗後VHR資料相對於初始VHR資料變化越小,說明該液晶組合物抗外界環境破壞能力越強,因此,該液晶組合物的信賴性就越高。The smaller the change of the VHR data after the aging test relative to the initial VHR data, the stronger the ability of the liquid crystal composition to resist damage from the external environment, therefore, the higher the reliability of the liquid crystal composition.

另外,將實施例1~8、對比例1~4液晶組合物灌注入液晶測試盒,進行殘像測試,測試結果一併示於下述的表16中。 表16 實施例1~8、對比例1~4液晶組合物信賴性測試資料   VHR(初始) VHR(紫外) VHR(背光1000H) 殘像 實施例1 96.45 93.25 82.51 實施例2 96.77 93.59 82.68 實施例3 96.51 93.15 82.04 實施例4 96.39 94.28 83.42 實施例5 96.29 94.55 83.61 實施例6 96.55 94.35 83.15 實施例7 96.62 94.24 83.28 實施例8 96.48 94.66 83.49 對比例1 96.38 94.32 83.22 對比例2 96.52 94.46 80.15 對比例3 96.34 94.18 76.84 對比例4 96.51 93.21 82.43 In addition, the liquid crystal compositions of Examples 1-8 and Comparative Examples 1-4 were poured into the liquid crystal test box, and the afterimage test was performed, and the test results are shown in Table 16 below. Table 16 Reliability test data of liquid crystal compositions of Examples 1-8 and Comparative Examples 1-4 VHR (initial) VHR (ultraviolet) VHR (backlight 1000H) afterimage Example 1 96.45 93.25 82.51 Example 2 96.77 93.59 82.68 Example 3 96.51 93.15 82.04 Example 4 96.39 94.28 83.42 Example 5 96.29 94.55 83.61 Example 6 96.55 94.35 83.15 Example 7 96.62 94.24 83.28 Example 8 96.48 94.66 83.49 Comparative example 1 96.38 94.32 83.22 Comparative example 2 96.52 94.46 80.15 Comparative example 3 96.34 94.18 76.84 Comparative example 4 96.51 93.21 82.43

從上述表16可以看出,本發明的實施例液晶組合物紫外、背光後的VHR下降較小,具有較高的抗紫外抗高溫能力,對殘像缺陷改善明顯。It can be seen from the above Table 16 that the liquid crystal composition of the embodiment of the present invention has a small decrease in VHR after ultraviolet light and backlight, has high anti-ultraviolet and high temperature resistance, and has obvious improvement on afterimage defects.

對實施例與對比例液晶組合物採用3.5V電壓驅動,延遲量為340nm的設計進行測試。由於對比例1、3介電各向異性較小,需要更大的電壓才能完全驅動,消耗更多的電能。採用與實施例6、對比例2相同的驅動電壓,對比例1、3無法完全驅動,透過率較小。實施例6與對比例2相比,垂直介電常數、ε⊥/Δε比值都更大,透過率更高。透過率的提高有利於背光的充分利用,從而降低背光亮度,降低能耗。The liquid crystal compositions of the examples and the comparative examples were driven by a voltage of 3.5V, and the retardation was designed to be 340nm. Since the dielectric anisotropy of Comparative Examples 1 and 3 is small, a larger voltage is required to fully drive and consume more electric energy. Using the same driving voltage as in Example 6 and Comparative Example 2, Comparative Examples 1 and 3 cannot be fully driven, and the transmittance is relatively small. Compared with Comparative Example 2, Example 6 has larger vertical permittivity, ε⊥/Δε ratio, and higher transmittance. The increase of the transmittance is conducive to the full use of the backlight, thereby reducing the brightness of the backlight and reducing energy consumption.

綜上所述,本發明的液晶組合物具有高的透過率、較高的光學各向異性、高的介電各向異性、高的垂直介電常數、高的ε⊥/Δε比值,較寬的向列相溫度範圍,以及抗紫外抗高溫能力強,無殘像缺陷的液晶組合物。本發明的液晶顯示元件、液晶顯示器通過包含前述的本發明的液晶組合物,具有高的對比度、面板輕薄、能耗低、較寬的使用溫度範圍,以及良好的信賴性。In summary, the liquid crystal composition of the present invention has high transmittance, high optical anisotropy, high dielectric anisotropy, high vertical permittivity, high ε⊥/Δε ratio, and a wide It is a liquid crystal composition with excellent nematic phase temperature range, strong UV resistance and high temperature resistance, and no afterimage defect. The liquid crystal display element and the liquid crystal display of the present invention contain the aforementioned liquid crystal composition of the present invention, and have high contrast, light and thin panel, low energy consumption, wide service temperature range, and good reliability.
