Description
本發明有關於一種含有聚醯胺酸(polyamic acid)或其衍生物和環氧化合物的液晶配向劑、由此液晶配向劑所形成的液晶配向膜、以及具備此液晶配向膜的液晶顯示元件。The present invention relates to a liquid crystal alignment agent containing polyamic acid or a derivative thereof and an epoxy compound, a liquid crystal alignment film formed by the liquid crystal alignment agent, and a liquid crystal display element including the liquid crystal alignment film.
液晶顯示元件被使用在筆記型電腦(note personal computer)或桌上型電腦(desktop computer)的監視器(monitor)、以及攝像機(video camera)的取景器(view finder)、投影式顯示器(projection display)等各種液晶顯示裝置中,近來也開始用在電視中。此外,液晶顯示元件也可以用作光學打印頭(optical printer head)、光學傅立葉變換元件(optical Fourier transform device)、光閥(light valve)等光電子學(optoelectronics)相關元件。The liquid crystal display element is used in a monitor of a note personal computer or a desktop computer, a view finder of a video camera, and a projection display. Among various liquid crystal display devices, etc., they have recently been used in televisions. Further, the liquid crystal display element can also be used as an optoelectronics related element such as an optical printer head, an optical Fourier transform device, and a light valve.
液晶顯示元件通常具有:1)對向配置的一對基板;2)形成在所述一對基板各自所對向的面中的一面或者兩面上的電極;3)形成在所述一對基板各自所對向的面上的液晶配向膜;以及4)形成在所述一對基板之間的液晶層。The liquid crystal display element generally has: 1) a pair of substrates disposed oppositely; 2) electrodes formed on one or both of the faces of the pair of substrates; 3) formed on each of the pair of substrates a liquid crystal alignment film on the opposite surface; and 4) a liquid crystal layer formed between the pair of substrates.
在先前的液晶顯示元件中,使用向列型液晶的顯示元件占主流,目前已經實際應用的有:1)扭轉90度的TN(Twisted Nematic,扭轉向列)型液晶顯示元件、2)通常扭轉180度以上的STN(Super Twisted Nematic,超扭轉向列)型液晶顯示元件、3)使用薄膜晶體管的所謂TFT(Thin Film Transistor,薄膜晶體管)型液晶顯示元件。但這些液晶顯示元件存在以下缺點:可以正確辨識圖像的視角狹窄,從斜方向上觀看時會産生亮度或對比度降低以及半色調下的亮度反轉(brightness inverse)。Among the former liquid crystal display elements, display elements using nematic liquid crystals are dominant, and currently practical applications include: 1) twisted 90 degree TN (Twisted Nematic) type liquid crystal display elements, 2) normal twisting An STN (Super Twisted Nematic) type liquid crystal display element of 180 degrees or more, and a so-called TFT (Thin Film Transistor) type liquid crystal display element using a thin film transistor. However, these liquid crystal display elements have the disadvantage that the angle of view of the image can be correctly recognized, and the brightness or contrast reduction and the brightness inverse at halftone are generated when viewed from an oblique direction.
近年來,此視角問題已經通過1)使用光學補償膜的TN-TFT型液晶顯示元件、2)採用垂直配向和光學補償膜的垂直配向(Vertical Alignment,VA)型液晶顯示元件、3)並用垂直配向和突起結構物技術的MVA(Multi Domain Vertical Alignment,多區域垂直配向)型液晶顯示元件、或者4)橫向電場方式的IPS(In-Plane Switching,面內切換)型液晶顯示元件、5)ECB(Electrically Controlled Birefringence,電控雙折射)型液晶顯示元件、6)光學補償彎曲(Optically Compensated Bend或者Optically self-Compensated Birefringence:OCB)型液晶顯示元件等技術而獲得了改良,經過改良的技術正實際應用,或者正在進行研究。In recent years, this viewing angle problem has been achieved by 1) TN-TFT type liquid crystal display elements using optical compensation films, 2) Vertical Alignment (VA) type liquid crystal display elements using vertical alignment and optical compensation films, and 3) vertical use MVA (Multi Domain Vertical Alignment) type liquid crystal display element of the alignment and protrusion structure technology, or 4) IPS (In-Plane Switching) type liquid crystal display element of the transverse electric field type, 5) ECB Improved (Electrically Controlled Birefringence) liquid crystal display device, 6) Optically Compensated Bend or Optically Self-Compensated Birefringence (OCB) liquid crystal display device, and improved technology Application, or ongoing research.
液晶顯示元件技術的發展不僅僅是只通過改良這些驅動方式或元件結構,也可以通過改良液晶顯示元件所使用的構成構件來達成。液晶顯示元件所使用的構成構件中,特別是液晶配向膜是關係到液晶顯示元件的顯示品質的重要因素之一,隨著液晶顯示元件品質的不斷提高,液晶配向膜的作用也變得越來越重要。The development of the liquid crystal display element technology is not only achieved by improving these driving methods or element structures, but also by improving the constituent members used for the liquid crystal display elements. Among the constituent members used for the liquid crystal display element, in particular, the liquid crystal alignment film is one of the important factors related to the display quality of the liquid crystal display element, and as the quality of the liquid crystal display element continues to increase, the role of the liquid crystal alignment film becomes more and more The more important.
液晶配向膜可以利用液晶配向劑來製備。目前主要使用的液晶配向劑是將聚醯胺酸或者可溶性聚醯亞胺(polyimide)溶解於有機溶劑中而成的溶液。將這種溶液塗布在基板上之後,通過加熱等手段進行成膜,而形成聚醯亞胺系配向膜。這種液晶配向劑例如已知有:作爲聚醯胺酸或其衍生物的原料的四羧酸二酐(tetracarboxylic dianhydride)及二胺(diamine)、和所表現的預傾角(pretilt angle)有所規定的液晶配向劑(例如,參照日本專利特開2002-62537號公報)。目前對聚醯胺酸以外的各種液晶配向劑也進行了研究,但是考慮到耐熱性、耐化學性(耐液晶性)、塗布性、液晶配向性、電特性、光學特性、顯示特性等方面,這些液晶配向劑幾乎未實際應用。The liquid crystal alignment film can be prepared by using a liquid crystal alignment agent. The liquid crystal alignment agent mainly used at present is a solution obtained by dissolving polylysine or a soluble polyimide in an organic solvent. After this solution is applied onto a substrate, film formation is carried out by heating or the like to form a polyimide film. Such a liquid crystal alignment agent is known, for example, as a tetracarboxylic dianhydride and a diamine as a raw material of polylysine or a derivative thereof, and a pretilt angle expressed. A liquid crystal alignment agent is prescribed (for example, refer to Japanese Laid-Open Patent Publication No. 2002-62537).

爲提高液晶顯示元件的顯示品質而要求液晶配向膜具備的重要特性,可以列舉離子密度。如果離子密度高,則在幀時間內施加在液晶上的電壓會降低,結果導致亮度下降,而阻礙正常的灰階顯示。另外,即使初始離子密度低,但是高溫加速試驗後離子密度(長期可靠性)增大等情況也是一個問題。In order to improve the display quality of the liquid crystal display element, an important characteristic of the liquid crystal alignment film is required, and an ion density can be cited. If the ion density is high, the voltage applied to the liquid crystal during the frame time is lowered, resulting in a decrease in brightness and hindering the normal gray scale display. In addition, even if the initial ion density is low, the ion density (long-term reliability) after the high-temperature acceleration test is increased, and the like is also a problem.
解決所述問題的嘗試已知有含有聚醯胺酸或其衍生物和規定量的具有噁嗪(oxazine)結構的化合物的液晶配向劑(例如,參照日本專利特開2007-286597號公報),但是隨著液晶顯示元件的技術的發展,業界對提供可解決所述問題的液晶配向劑的要求越來越迫切。An attempt to solve the problem is known as a liquid crystal alignment agent containing a poly-proline or a derivative thereof and a predetermined amount of a compound having an oxazine structure (for example, refer to Japanese Laid-Open Patent Publication No. 2007-286597). However, with the development of the technology of liquid crystal display elements, the industry is increasingly demanding to provide liquid crystal alignment agents that can solve the problems.
考慮到以上情況,業界期待開發出一種離子密度及長期可靠性的問題獲得改善的液晶顯示元件用液晶配向劑,使用此液晶配向劑所形成的液晶配向膜,以及具備此液晶配向膜的液晶顯示元件。In view of the above, the industry is expected to develop a liquid crystal alignment agent for liquid crystal display elements having improved ion density and long-term reliability, a liquid crystal alignment film formed using the liquid crystal alignment agent, and a liquid crystal display having the liquid crystal alignment film. element.

本發明的液晶配向劑中的聚醯胺酸或其衍生物的含有率,可以根據將液晶配向劑塗布到基板上的塗布方法來選擇。例如,如果是用於普通液晶顯示元件的製造步驟所使用的印刷機(包括膠版印刷機(offset printer)或噴墨印刷機(ink jet printer)。以下有時簡稱爲“印刷機”。)的液晶配向劑,則聚醯胺酸或其衍生物的含有率優選0.5重量%~30重量%,更優選1重量%~15重量%,所述聚醯胺酸或其衍生物的含有率可以根據與液晶配向劑的黏度(下述)之間的關係來適當調整。The content of polyphthalic acid or a derivative thereof in the liquid crystal alignment agent of the present invention can be selected according to a coating method in which a liquid crystal alignment agent is applied onto a substrate. For example, it is a printing machine (including an offset printer or an ink jet printer) used for a manufacturing step of a general liquid crystal display element. Hereinafter, it is sometimes simply referred to as a "printing machine". In the liquid crystal alignment agent, the content of the polyaminic acid or a derivative thereof is preferably 0.5% by weight to 30% by weight, more preferably 1% by weight to 15% by weight, and the content of the polyaminic acid or a derivative thereof may be based on The relationship between the viscosity of the liquid crystal alignment agent (described below) is appropriately adjusted.
本發明的液晶配向劑的黏度根據塗布方法、聚醯胺酸或其衍生物的濃度、所使用的聚醯胺酸或其衍生物的種類、溶劑的種類和比例的不同而多種多樣。例如,當使用印刷機來進行塗布時,液晶配向劑的黏度優選5mPa‧s~100mPa‧s,更優選10mPa‧s~80mPa‧s。如果液晶配向劑的黏度小於5mPa‧s,則液晶配向膜會難以獲得足够的膜厚;如果液晶配向劑的黏度大於100mPa‧s,則印刷不勻會增大。通過旋轉塗布法來塗布液晶配向劑時,液晶配向劑的黏度優選5mPa‧s~200mPa‧s,更優選10mPa‧s~100mPa‧s。The viscosity of the liquid crystal alignment agent of the present invention varies depending on the coating method, the concentration of the polyaminic acid or its derivative, the type of the polyaminic acid or its derivative used, and the type and ratio of the solvent.

If the viscosity of the liquid crystal alignment agent is less than 5 mPa‧s, it may be difficult to obtain a sufficient film thickness for the liquid crystal alignment film; if the viscosity of the liquid crystal alignment agent is more than 100 mPa‧s, the unevenness of printing may increase. When the liquid crystal alignment agent is applied by a spin coating method, the viscosity of the liquid crystal alignment agent is preferably 5 mPa ‧ to 200 mPa ‧ s, and more preferably 10 mPa ‧ to 100 mPa ‧ s

Further, when the use of the liquid crystal alignment film is used in a liquid crystal display device of a transverse electric field type such as an IPS type liquid crystal display element, it is preferable to subject the liquid crystal alignment film to a rubbing treatment.
所述液晶配向膜的膜厚可以根據液晶配向劑的黏度或者液晶配向劑的塗布方法來進行調整。另外,液晶配向膜的膜厚可以使用階差計或橢偏儀(ellipsometer)等衆所周知的膜厚測定裝置來測定。並且,可以根據需要對液晶配向膜進行水解等處理,並利用IR或者質譜法(Mass Spectrometry,MS)等常用的分析方法來分析液晶配向膜中的成分。例如,“Performance improvement of polybenzoxazine by alloying with polyamide:effect of preparation method on the properties”(Tsutomu Takeichi et. al.,polymer,2005,46,p.4909-4916)中,記載了通過IR來對將聚醯胺酸醯亞胺化而成的膜中的噁嗪化合物進行分析的方法。The film thickness of the liquid crystal alignment film can be adjusted according to the viscosity of the liquid crystal alignment agent or the coating method of the liquid crystal alignment agent.

<3.電特性的評價><3. Evaluation of electrical characteristics>
以如下方式測定實施例1~實施例20、比較例1~比較例21所製作的液晶顯示元件的離子密度和長期可靠性。The ion density and long-term reliability of the liquid crystal display elements produced in Examples 1 to 20 and Comparative Examples 1 to 21 were measured in the following manner.
1)離子密度的測定1) Determination of ion density
使用Toyo Technica製造的液晶物性評價裝置6254型來測定離子密度。測定條件如下:波形爲三角波;頻率爲0.01Hz;電壓爲±10V;測定溫度爲60℃。測得的離子密度的值越小,電特性就越好。將結果示於表2、表3。The ion density was measured using a liquid crystal property evaluation device 6254 manufactured by Toyo Technica. The measurement conditions were as follows: the waveform was a triangular wave; the frequency was 0.01 Hz; the voltage was ±10 V; and the measurement temperature was 60 °C. The smaller the value of the measured ion density, the better the electrical characteristics. The results are shown in Table 2 and Table 3.
2)離子密度的保持特性的測定2) Determination of retention characteristics of ion density
針對所製作的液晶顯示元件,隨著時間經過測定離子密度[pC],並且對離子密度的保持特性進行評價。保持特性的試驗方法可以採用如下方法:將液晶顯示元件放置在溫度爲100℃的環境中,隨著時間經過中途取出此液晶顯示元件並測定其離子密度[pC]。200小時後的離子密度的數值越小,離子密度的保持特性就越好,並且電特性的長期可靠性就越好。將100小時後和200小時後的數據示於表2、表3。With respect to the produced liquid crystal display element, the ion density [pC] was measured over time, and the ion density retention characteristics were evaluated. As a test method for maintaining characteristics, a liquid crystal display element can be placed in an environment at a temperature of 100 ° C, and the liquid crystal display element is taken out over time and its ion density [pC] is measured. The smaller the value of the ion density after 200 hours, the better the ion density retention property and the longer the long-term reliability of the electrical characteristics. The data after 100 hours and after 200 hours are shown in Table 2 and Table 3.
如表2、表3所示,使用添加了環氧化合物的實施例1~實施例20的液晶配向劑的液晶顯示元件可以抑制離子密度隨著時間經過而增大。As shown in Table 2 and Table 3, the liquid crystal display element using the liquid crystal alignment agents of Examples 1 to 20 to which the epoxy compound was added can suppress the increase in ion density with time.
<4.配向特性的評價><4. Evaluation of alignment characteristics>
對於實施例1、3、5、7、9、11、12以及比較例1~比較例12中所製作的液晶顯示元件,將注入液晶組合物後、加 熱處理前的此元件夾在兩塊偏向板之間,貼裝背光源(back light),觀察液晶的配向狀態,根據是否存在流動配向(flow orientation)來評價配向特性。不存在流動配向的液晶顯示元件可以認為配向性良好。將結果示於表4。In the liquid crystal display elements produced in Examples 1, 3, 5, 7, 9, 11, 12 and Comparative Examples 1 to 12, after the liquid crystal composition was injected, This element before heat treatment was sandwiched between two deflecting plates, and a back light was attached to observe the alignment state of the liquid crystal, and the alignment characteristics were evaluated based on whether or not there was a flow orientation. A liquid crystal display element in which no flow alignment is present can be considered to have good alignment. The results are shown in Table 4.
如表4所示,此次所研發的添加有環氧化合物的液晶配向劑,即使添加環氧化合物,也未確認到流動配向,可以維持高配向性。As shown in Table 4, the liquid crystal alignment agent to which the epoxy compound was added, which was developed this time, did not confirm the flow alignment even when an epoxy compound was added, and the high alignment property was maintained.
