Description
本發明是有關於一種化合物、液晶組成物及液晶顯示元件。更詳細而言,本發明是有關於一種兼具甲基丙烯醯氧基等聚合性基與兩個經-OH基等極性基取代的丙烯醯氧基等聚合性基的化合物、包含該化合物且介電常數各向異性為正或負的液晶組成物及包含該組成物或其一部分硬化物的液晶顯示元件。The invention relates to a compound, a liquid crystal composition and a liquid crystal display element. More specifically, the present invention relates to a compound having a polymerizable group such as methacryloxy group and two polymerizable groups such as acryloxy group substituted by polar groups such as -OH group, including the compound and A liquid crystal composition having a positive or negative dielectric anisotropy and a liquid crystal display device comprising the composition or a part of its cured product.
若基於液晶分子的運作模式而對液晶顯示元件進行分類,則可分類為相變(phase change,PC)、扭轉向列(twisted nematic,TN)、超扭轉向列(super twisted nematic,STN)、電控雙折射(electrically controlled birefringence,ECB)、光學補償彎曲(optically compensated bend,OCB)、共面切換(in-plane switching,IPS)、垂直配向(vertical alignment,VA)、邊緣場切換(fringe field switching,FFS)、電場感應光反應配向(field-induced photo-reactive alignment,FPA)等模式。另外,若基於元件的驅動方式,則可分類為被動矩陣(passive matrix,PM)與主動矩陣(active matrix,AM)。PM被分類為靜態式(static)、多工式(multiplex)等,AM被分類為薄膜電晶體(thin film transistor,TFT)、金屬-絕緣體-金屬(metal insulator metal,MIM)等。進而,TFT可分類為非晶矽(amorphous silicon)及多晶矽(polycrystal silicon)。後者根據製造步驟而分類為高溫型與低溫型。若進行基於光源的分類,則可分類為利用自然光的反射型、利用背光的透過型、以及利用自然光與背光這兩者的半透過型。If liquid crystal display elements are classified based on the operation mode of liquid crystal molecules, they can be classified into phase change (phase change, PC), twisted nematic (twisted nematic, TN), super twisted nematic (super twisted nematic, STN), Electrically controlled birefringence (ECB), optically compensated bend (OCB), in-plane switching (IPS), vertical alignment (vertical alignment, VA), fringe field switching (fringe field switching (FFS), field-induced photo-reactive alignment (FPA) and other modes. In addition, if the drive method is based on components, it can be classified into passive matrix (passive matrix, PM) and active matrix (active matrix, AM). PM is classified into static type (static), multiplex type (multiplex), etc., AM is classified into thin film transistor (thin film transistor, TFT), metal-insulator-metal (metal insulator metal, MIM), etc. Furthermore, TFT can be classified into amorphous silicon (amorphous silicon) and polycrystalline silicon (polycrystalline silicon). The latter are classified into high temperature type and low temperature type according to the manufacturing steps. When classified based on the light source, it can be classified into reflective type utilizing natural light, transmissive type utilizing backlight, and transflective type utilizing both natural light and backlight.
具有向列相的液晶組成物具有適當的特性。藉由提高該組成物的特性,可獲得具有良好特性的AM元件。將所述組成物的特性與AM元件的特性的關聯歸納於下述表1中。A liquid crystal composition having a nematic phase has suitable characteristics. By improving the properties of this composition, an AM device with good properties can be obtained. The correlation between the properties of the composition and the properties of the AM device is summarized in Table 1 below.
基於市售的AM元件來對所述組成物的特性進一步進行說明。向列相的溫度範圍(呈現向列相的溫度範圍)與元件可使用的溫度範圍相關聯。向列相的較佳的上限溫度為約70℃以上,而且向列相的較佳的下限溫度為約-10℃以下。 所述組成物的黏度與元件的響應時間相關聯。為了以元件顯示動態圖像,較佳為響應時間短。理想為短於1毫秒的響應時間。因此,較佳為所述組成物的黏度低,進而,更佳為即便於低溫下,所述組成物的黏度亦低。The characteristics of the composition will be further described based on a commercially available AM device. The temperature range of the nematic phase (the temperature range in which the nematic phase appears) is associated with the usable temperature range of the element. A preferable upper limit temperature of the nematic phase is about 70°C or higher, and a preferable lower limit temperature of the nematic phase is about -10°C or lower. The viscosity of the composition correlates with the response time of the element. In order to display a moving image with a device, it is preferable that the response time is short. A response time of less than 1 millisecond is ideal. Therefore, it is preferable that the viscosity of the composition is low, and it is more preferable that the viscosity of the composition is low even at low temperature.
所述組成物的光學各向異性與元件的對比度相關聯。根據元件的模式,需要光學各向異性大或光學各向異性小,即光學各向異性適當。組成物的光學各向異性(Δn)與元件的單元間隙(d)的積(Δn×d)被設計成使對比度成為最大。積的適當值依存於運作模式的種類。於TN等模式的元件中,該值為約0.45 μm。於VA模式的元件中,該值為約0.30 μm至約0.40 μm的範圍,於IPS模式或FFS模式的元件中,該值為約0.20 μm至約0.30 μm的範圍。該些情況下,對單元間隙小的元件而言較佳為具有大的光學各向異性的組成物。 所述組成物的介電常數各向異性大有助於元件的臨限電壓低、消耗電力小與對比度大。因此,較佳為正或負的介電常數各向異性大。組成物的比電阻大有助於元件的電壓保持率大與對比度大。因此,較佳為於初始階段中不僅於室溫下,而且於接近於向列相的上限溫度的溫度下亦具有大的比電阻的組成物。較佳為於長時間使用後,不僅於室溫下而且於接近向列相的上限溫度的溫度下亦具有大的比電阻的組成物。 組成物對紫外線及熱的穩定性與元件的壽命相關聯。於該穩定性高時,元件的壽命長。此種特性對於液晶投影儀、液晶電視等中所使用的AM元件而言較佳。The optical anisotropy of the composition correlates with the contrast of the element. Depending on the mode of the element, it is necessary to have large optical anisotropy or small optical anisotropy, that is, to have appropriate optical anisotropy. The product (Δn×d) of the optical anisotropy (Δn) of the composition and the cell gap (d) of the device is designed so as to maximize the contrast. The appropriate value of the product depends on the type of operation mode. In devices of TN and other modes, this value is about 0.45 μm. In the device of VA mode, the value is in the range of about 0.30 μm to about 0.40 μm, and in the device of IPS mode or FFS mode, the value is in the range of about 0.20 μm to about 0.30 μm. In these cases, a composition having a large optical anisotropy is preferable for a device having a small cell gap. The large dielectric anisotropy of the composition contributes to the low threshold voltage, low power consumption and high contrast of the device. Therefore, it is preferable that the positive or negative dielectric constant anisotropy is large. The high specific resistance of the composition contributes to high voltage retention and high contrast of the device. Therefore, a composition having a large specific resistance not only at room temperature but also at a temperature close to the upper limit temperature of the nematic phase in the initial stage is preferable. It is preferably a composition having a large specific resistance not only at room temperature but also at a temperature close to the upper limit temperature of the nematic phase after long-term use. The stability of the composition to ultraviolet light and heat is related to the lifetime of the device. When the stability is high, the life of the device is long. Such characteristics are preferable for AM elements used in liquid crystal projectors, liquid crystal televisions, and the like.
於聚合物穩定配向(polymer sustained alignment,PSA)型的液晶顯示元件中,使用含有聚合體的液晶組成物。首先,將添加有少量聚合性化合物的組成物注入至元件中。此處,一般使用具有多個聚合性基的聚合性化合物。其次,一面對夾持該元件的基板之間施加電壓,一面對組成物照射紫外線。聚合性化合物進行聚合而於組成物中生成聚合體的網狀結構。若使用該組成物,則可藉由聚合體來控制液晶分子的配向,因此元件的響應時間縮短,圖像的殘像得以改善。具有TN、ECB、OCB、IPS、VA、FFS、FPA等模式的元件可期待聚合體的此種效果。A liquid crystal composition containing a polymer is used in a polymer sustained alignment (PSA) type liquid crystal display device. First, a composition added with a small amount of a polymerizable compound is injected into the device. Here, generally, a polymerizable compound having a plurality of polymerizable groups is used. Next, while applying a voltage between the substrates sandwiching the device, ultraviolet rays are irradiated to the composition. The polymerizable compound polymerizes to form a polymer network structure in the composition. If this composition is used, the alignment of the liquid crystal molecules can be controlled by the polymer, so the response time of the device is shortened and the afterimage of the image is improved. Such an effect of polymers can be expected for devices having modes such as TN, ECB, OCB, IPS, VA, FFS, and FPA.
於通用的液晶顯示元件中,液晶分子的垂直配向是藉由聚醯亞胺配向膜來達成。另一方面,作為不具有配向膜的液晶顯示元件,提出有將極性化合物添加至液晶組成物中,而使液晶分子配向的模式。首先,將添加有少量極性化合物及少量聚合性化合物的組成物注入至元件中。作為該聚合性化合物,一般使用具有多個聚合性基的聚合性化合物。此處,藉由極性化合物的作用而液晶分子進行配向。其次,一面對夾持該元件的基板之間施加電壓,一面對組成物照射紫外線。此處,聚合性化合物進行聚合,並使液晶分子的配向穩定化。若使用該組成物,則可藉由極性化合物及聚合體來控制液晶分子的配向,因此元件的響應時間縮短,圖像的殘像得以改善。進而,於不具有配向膜的元件中,不需要形成配向膜的步驟。由於不存在配向膜,故不存在元件的電阻因配向膜與組成物的相互作用而降低的情況。具有TN、ECB、OCB、IPS、VA、FFS、FPA等模式的元件可期待利用極性化合物與聚合體的組合的此種效果。In common liquid crystal display elements, the vertical alignment of liquid crystal molecules is achieved by polyimide alignment films. On the other hand, as a liquid crystal display element without an alignment film, a mode in which a polar compound is added to a liquid crystal composition to align liquid crystal molecules has been proposed. First, a composition added with a small amount of polar compound and a small amount of polymerizable compound is injected into the device. As the polymerizable compound, a polymerizable compound having a plurality of polymerizable groups is generally used. Here, the liquid crystal molecules are aligned by the action of the polar compound. Next, while applying a voltage between the substrates sandwiching the device, ultraviolet rays are irradiated to the composition. Here, the polymerizable compound polymerizes and stabilizes the alignment of liquid crystal molecules. If this composition is used, the alignment of the liquid crystal molecules can be controlled by the polar compound and the polymer, so the response time of the device is shortened and the afterimage of the image is improved. Furthermore, in an element without an alignment film, the step of forming an alignment film is unnecessary. Since there is no alignment film, the resistance of the device does not decrease due to the interaction between the alignment film and the composition. Devices having modes such as TN, ECB, OCB, IPS, VA, FFS, and FPA can be expected to have such an effect utilizing a combination of a polar compound and a polymer.

該說明書中的用語的使用方法如下所述。有時將用語「液晶性化合物」、「液晶組成物」、及「液晶顯示元件」分別簡稱為「化合物」、「組成物」、及「元件」。 「液晶性化合物」是具有向列相、層列相等液晶相的化合物,及雖不具有液晶相,但出於調節上限溫度、下限溫度、黏度、介電常數各向異性等組成物的物性的目的而添加的化合物的總稱。該化合物通常具有1,4-伸環己基或1,4-伸苯基等六員環,且其分子結構為棒狀(rod like)。 「聚合性化合物」是出於在組成物中生成聚合體的目的而添加的化合物。具有烯基的液晶性化合物於其意義方面並非為聚合性化合物。 「極性化合物」是藉由極性基與基板表面等相互作用而幫助液晶分子排列。 「液晶顯示元件」為液晶顯示面板及液晶顯示模組等的總稱。The usage of the terms in this specification is as follows. The terms "liquid crystal compound", "liquid crystal composition", and "liquid crystal display device" are sometimes abbreviated as "compound", "composition", and "device", respectively. "Liquid crystal compound" is a compound that has a nematic phase or a smectic liquid crystal phase, and does not have a liquid crystal phase, but is used to adjust the physical properties of the composition such as upper limit temperature, lower limit temperature, viscosity, and dielectric constant anisotropy. A general term for compounds added for purpose. This compound usually has a six-membered ring such as 1,4-cyclohexylene or 1,4-phenylene, and its molecular structure is rod-like. A "polymerizable compound" is a compound added for the purpose of forming a polymer in the composition. A liquid crystal compound having an alkenyl group is not a polymerizable compound in its meaning. "Polar compounds" help liquid crystal molecules to align by interacting with polar groups and substrate surfaces. "Liquid crystal display device" is a general term for liquid crystal display panels, liquid crystal display modules, and the like.
液晶組成物通常藉由將多種液晶性化合物混合來製備。於該組成物中,出於進一步調整物性的目的而視需要來添加聚合性化合物、聚合起始劑、聚合抑制劑、光學活性化合物、抗氧化劑、紫外線吸收劑、光穩定劑、熱穩定劑、色素、及消泡劑等添加物。關於液晶組成物中的液晶性化合物的比例(含量),即便於添加有添加物的情況下,亦是由基於不包含添加物的液晶組成物的重量的重量百分率(重量%)來表示。液晶組成物中的添加物的比例(添加量)是由基於不包含添加物的液晶組成物的重量的重量百分率(重量%)來表示。即,液晶性化合物或添加物的比例是基於液晶性化合物的總重量而算出。有時亦使用重量百萬分率(ppm)。液晶組成物中的聚合起始劑及聚合抑制劑的比例是例外地基於聚合性化合物的重量來表示。A liquid crystal composition is usually prepared by mixing various liquid crystal compounds. To this composition, polymerizable compounds, polymerization initiators, polymerization inhibitors, optically active compounds, antioxidants, ultraviolet absorbers, light stabilizers, heat stabilizers, Additives such as pigments and defoamers. The ratio (content) of the liquid crystal compound in the liquid crystal composition is represented by weight percentage (wt%) based on the weight of the liquid crystal composition not including the additive even when additives are added. The ratio (addition amount) of the additive in the liquid crystal composition is represented by weight percentage (wt%) based on the weight of the liquid crystal composition not containing the additive. That is, the ratio of the liquid crystal compound or the additive is calculated based on the total weight of the liquid crystal compound. Parts per million (ppm) by weight are also sometimes used. The ratio of the polymerization initiator and the polymerization inhibitor in the liquid crystal composition is exceptionally expressed based on the weight of the polymerizable compound.
「透明點」為液晶性化合物中的液晶相-各向同性相的轉變溫度。「液晶相的下限溫度」為液晶性化合物中的固體-液晶相(層列相、向列相等)的轉變溫度。「向列相的上限溫度」為液晶性化合物與母液晶的混合物或液晶組成物中的向列相-各向同性相的轉變溫度,有時簡稱為「上限溫度」。有時將「向列相的下限溫度」簡稱為「下限溫度」。「提高介電常數各向異性」或「大的介電常數各向異性」的表述是指其值的絕對值增加或大。所謂「電壓保持率大」是指元件於初始階段中不僅於室溫下,而且於接近上限溫度的溫度下亦具有大的電壓保持率,而且於將元件長時間使用後,不僅於室溫下而且於接近上限溫度的溫度下亦具有大的電壓保持率。於組成物或元件中,有時於經時變化試驗(包含加速劣化試驗)的前後研究特性。「於液晶組成物中的溶解度高」的表述是指相對於常溫下的包含液晶性化合物的組成物的任一者,溶解度均高,但作為該組成物,可將用以在下述實施例中對溶解性進行評價的組成物設為基準。The "clearing point" is the transition temperature between a liquid crystal phase and an isotropic phase in a liquid crystal compound. The "lower limit temperature of a liquid crystal phase" is the transition temperature of a solid-liquid crystal phase (smectic phase, nematic phase) in a liquid crystal compound. The "upper limit temperature of the nematic phase" is the transition temperature from the nematic phase to the isotropic phase in the mixture of the liquid crystal compound and the mother liquid crystal or the liquid crystal composition, and is sometimes simply referred to as the "upper limit temperature". The "lower limit temperature of the nematic phase" is sometimes simply referred to as the "lower limit temperature". The expression "increased dielectric constant anisotropy" or "large dielectric constant anisotropy" means that the absolute value of the value is increased or large. The so-called "large voltage retention rate" means that the device has a large voltage retention rate not only at room temperature in the initial stage, but also at a temperature close to the upper limit temperature, and after using the device for a long time, not only at room temperature Moreover, it also has a large voltage retention rate at a temperature close to the upper limit temperature. In a composition or device, characteristics may be studied before and after a time-dependent change test (including accelerated deterioration test). The expression "high solubility in the liquid crystal composition" means that the solubility is high with respect to any composition containing liquid crystal compounds at room temperature, but as this composition, it can be used in the following examples The composition evaluated for solubility was used as a reference.
有時將式(1)所表示的化合物簡稱為「化合物(1)」。化合物(1)是指式(1)所表示的一種化合物、兩種化合物的混合物、或三種以上化合物的混合物。該規則亦適用於選自式(2)所表示的化合物的群組中的至少一種化合物等。 由六邊形包圍的A1 、B1 、C1 等記號分別與環A1 、環B1 、環C1 等相對應。六邊形表示環己烷環或苯環等六員環或者萘環等縮合環。橫切該六邊形的一邊的直線表示環上的任意的氫可經-Sp1 -P1 等基取代。 f、g、h等下標表示經取代的基的個數。於下標為0時,不存在此種取代。 於「環A及環C獨立地為X、Y、或Z」的表述中,由於主語為多個,故使用「獨立地」。於主語為「環A為」時,由於主語為單個,故不使用「獨立地」。The compound represented by formula (1) may be simply referred to as "compound (1)". Compound (1) refers to one compound represented by formula (1), a mixture of two compounds, or a mixture of three or more compounds. This rule also applies to at least one compound selected from the group of compounds represented by formula (2), and the like. Symbols such as A 1 , B 1 , and C 1 surrounded by a hexagon correspond to ring A 1 , ring B 1 , ring C 1 , etc., respectively. The hexagon represents a six-membered ring such as a cyclohexane ring or a benzene ring, or a condensed ring such as a naphthalene ring. A straight line crossing one side of the hexagon indicates that any hydrogen on the ring may be substituted by groups such as -Sp 1 -P 1 . Subscripts such as f, g, and h indicate the number of substituted groups. When the subscript is 0, there is no such substitution. In the expression "ring A and ring C are independently X, Y, or Z", since there are plural subjects, "independently" is used. When the subject is "ring A is", since the subject is singular, "independently" is not used.
於化合物的化學式中,將末端基R11 的記號用於多種化合物中,但該些化合物中的R11 所表示的基分別可相同,或亦可不同。例如,於化合物(2)的R11 為乙基的情況下,化合物(3)的R11 可為乙基,亦可為丙基等其他基。該規則亦適用於其他記號。化合物(8)中,於i為2時,存在兩個環D1 。該化合物中,兩個環D1 所表示的兩個基可相同,或亦可不同。於i大於2時,亦適用於任意的兩個環D1 。該規則亦適用於其他記號。In the chemical formula of the compound, the symbol of the terminal group R 11 is used in various compounds, but the groups represented by R 11 in these compounds may be the same or different. For example, when R 11 of compound (2) is ethyl, R 11 of compound (3) may be ethyl or other groups such as propyl. This rule also applies to other tokens. In compound (8), when i is 2, two rings D 1 exist. In this compound, the two groups represented by the two rings D 1 may be the same or different. When i is greater than 2, it is also applicable to any two rings D 1 . This rule also applies to other tokens.
「至少一個‘A’」的表述是指‘A’的個數為任意。「至少一個‘A’可經‘B’取代」的表述包含未經‘B’取代的‘A’本身的情況、一個‘A’經‘B’取代的情況、兩個以上的‘A’經‘B’取代的情況,該些情況中,經‘B’取代的‘A’位置為任意。取代位置為任意的規則亦適用於「至少一個‘A’經‘B’取代」的表述。「至少一個A可經B、C、或D取代」的表述是指包含A未經取代的情況、至少一個A經B取代的情況、至少一個A經C取代的情況、及至少一個A經D取代的情況、以及多個A經B、C、D的至少兩個取代的情況。例如,至少一個-CH2 -(或-CH2 CH2 -)可經-O-(或-CH=CH-)取代的烷基中,包含烷基、烯基、烷氧基、烷氧基烷基、烷氧基烯基、烯氧基烷基。再者,連續的兩個-CH2 -經-O-取代而成為-O-O-的情況欠佳。於烷基等中,甲基部分(-CH2 -H)的-CH2 -經-O-取代而成為-O-H的情況亦欠佳。The expression "at least one 'A'" means that the number of 'A' is arbitrary. The expression "at least one 'A' may be substituted by 'B'" includes the case where 'A' itself is not substituted by 'B', the case where one 'A' is substituted by 'B', the case where two or more 'A's are In the case of 'B' substitution, in these cases, the position of 'A' substituted with 'B' is arbitrary. The rule that substitution positions are arbitrary also applies to the expression "at least one 'A' is substituted with 'B'". The expression "at least one A may be substituted by B, C, or D" refers to the case where A is unsubstituted, the case where at least one A is substituted by B, the case where at least one A is substituted by C, and the case where at least one A is substituted by D The case of substitution, and the case of a plurality of A being substituted by at least two of B, C, and D. For example, at least one -CH 2 - (or -CH 2 CH 2 -) can be substituted by -O- (or -CH=CH-) in the alkyl group, including alkyl, alkenyl, alkoxy, alkoxy Alkyl, alkoxyalkenyl, alkenyloxyalkyl. Furthermore, the case where two consecutive -CH 2 -s are substituted with -O- to become -OO- is unfavorable. In an alkyl group or the like, it is also unfavorable that -CH 2 - in the methyl moiety (-CH 2 -H) is substituted with -O- to become -OH.
有時使用「R11 及R12 獨立地為碳數1至10的烷基或碳數2至10的烯基,該烷基及烯基中,至少一個-CH2 -可經-O-取代,該些基中,至少一個氫可經氟取代」的表述。該表述中,「該些基中」可按照語句進行解釋。於該表述中,「該些基」是指烷基、烯基、烷氧基、烯氧基等。即,「該些基」表示用語「該些基中」之前所記載的所有基。該常識性解釋亦適用於其他用語。Sometimes "R 11 and R 12 are independently an alkyl group with 1 to 10 carbons or an alkenyl group with 2 to 10 carbons, in which at least one -CH 2 - may be substituted by -O- , in these groups, at least one hydrogen may be substituted by fluorine". In this expression, "these bases" can be interpreted according to the sentence. In this expression, "the groups" refer to alkyl, alkenyl, alkoxy, alkenyloxy and the like. That is, "the groups" means all the groups described before the term "in the groups". This commonsense interpretation applies to other terms as well.
鹵素是指氟、氯、溴、或碘。較佳的鹵素為氟或氯。進而佳的鹵素為氟。液晶性化合物中,烷基為直鏈狀或分支狀,且不包含環狀烷基。一般而言,直鏈狀烷基優於分支狀烷基。該些情況對於烷氧基、烯基等末端基而言亦相同。關於與1,4-伸環己基相關的立體構型,為了提高向列相的上限溫度,反式構型優於順式構型。2-氟-1,4-伸苯基是指下述兩個二價基。化學式中,氟可向左(L),亦可向右(R)。該規則亦適用於四氫吡喃-2,5-二基等藉由自環中去除兩個氫而生成的左右非對稱的二價基。Halogen means fluorine, chlorine, bromine, or iodine. Preferred halogens are fluorine or chlorine. A further preferred halogen is fluorine. In the liquid crystal compound, the alkyl group is linear or branched, and does not contain a cyclic alkyl group. In general, straight-chain alkyl groups are preferred over branched ones. The same applies to terminal groups such as alkoxy and alkenyl. Regarding the configuration related to 1,4-cyclohexylene, the trans configuration is preferable to the cis configuration in order to increase the upper limit temperature of the nematic phase. 2-Fluoro-1,4-phenylene refers to the following two divalent groups. In the chemical formula, fluorine can be left (L) or right (R).

於聚合物穩定配向型的元件中,組成物所含的聚合體使液晶分子配向。極性化合物幫助液晶分子排列。即,極性化合物可代替配向膜而使用。製造此種元件的方法的一例如下所述。準備具有被稱為陣列基板與彩色濾光片基板的兩片基板的元件。該基板不具有配向膜。該基板的至少一片具有電極層。將液晶性化合物混合而製備液晶組成物。於該組成物中添加化合物(1)、以及視需要的其他聚合性化合物及極性化合物。視需要亦可進一步添加添加物。將該組成物注入至元件中。於對該元件施加電壓的狀態下進行光照射。較佳為紫外線。藉由光照射而使聚合性化合物聚合。藉由該聚合而生成包含聚合體的組成物,從而製作具有PSA模式的元件。In polymer-stabilized alignment-type devices, the polymer contained in the composition aligns the liquid crystal molecules. Polar compounds help the liquid crystal molecules to align. That is, a polar compound may be used instead of the alignment film. An example of a method of manufacturing such an element is as follows. A device having two substrates called an array substrate and a color filter substrate is prepared. This substrate does not have an alignment film. At least one of the substrates has an electrode layer. Liquid crystal compounds are mixed to prepare a liquid crystal composition. Compound (1), and optionally other polymerizable compounds and polar compounds are added to this composition. Additives can also be further added as needed. The composition is injected into the device. Light irradiation was performed with a voltage applied to the element. Ultraviolet rays are preferred. The polymerizable compound is polymerized by light irradiation. By this polymerization, a composition containing a polymer is produced, and a device having a PSA mode is produced.
該程序中,極性化合物由於極性基與基板表面相互作用,故於基板上排列。該極性化合物使液晶分子配向。於存在多個極性基的情況下,與基板表面的相互作用變得更強,可以低濃度進行配向。於施加電壓時,藉由電場的作用來進一步促進液晶分子的配向。依據該配向,聚合性化合物亦進行配向。於該狀態下聚合性化合物藉由紫外線而聚合,因此生成維持所述配向的聚合體。藉由該聚合體的效果,液晶分子的配向追加地穩定化,因此元件的響應時間縮短。由於圖像的殘像為液晶分子的運作不良,故藉由該聚合體的效果而亦同時改善殘像。化合物(1)為聚合性,因此藉由聚合而被消耗。化合物(1)亦藉由與其他聚合性化合物進行共聚而被消耗。因此,化合物(1)雖具有極性基,但被消耗,因此可獲得電壓保持率大的液晶顯示元件。再者,若使用具有聚合性的極性化合物,則可以一種化合物達成極性化合物與聚合性化合物這兩者的效果,因此亦有時不需要不具有極性基的聚合性化合物。 [實施例]In this procedure, polar compounds are aligned on the substrate due to the interaction of the polar groups with the substrate surface. The polar compound aligns the liquid crystal molecules. In the presence of a plurality of polar groups, the interaction with the substrate surface becomes stronger, and alignment can be performed at a low concentration. When the voltage is applied, the alignment of the liquid crystal molecules is further promoted by the action of the electric field. According to this alignment, the polymerizable compound also aligns. In this state, the polymerizable compound is polymerized by ultraviolet light, thereby producing a polymer that maintains the above-mentioned alignment. Due to the effect of the polymer, the alignment of the liquid crystal molecules is additionally stabilized, so the response time of the device is shortened. Since the afterimage of the image is due to the poor operation of the liquid crystal molecules, the effect of the polymer also improves the afterimage at the same time. Compound (1) is polymerizable, so it is consumed by polymerization. Compound (1) is also consumed by copolymerization with other polymerizable compounds. Therefore, although compound (1) has a polar group, since it is consumed, the liquid crystal display element with a high voltage retention ratio can be obtained. Furthermore, if a polymerizable polar compound is used, the effects of both the polar compound and the polymerizable compound can be achieved with one compound, and therefore a polymerizable compound not having a polar group may not be necessary.

Therefore, the compound of the present application can be said to be an excellent compound having a large compatibility.
