Description

液晶顯示元件、液晶組成物、及其用途及化合物及其用途Liquid crystal display element, liquid crystal composition, use thereof, compound and use thereof

本發明是有關於一種含有介電各向異性為負的液晶組成物的液晶顯示元件、液晶組成物及化合物。尤其是有關於一種利用了液晶組成物的液晶顯示元件，所述液晶組成物含有在部分結構中具有伸乙烯基（vinylene group）的配向性單體，並藉由該化合物的作用而可達成液晶分子的配向。The present invention relates to a liquid crystal display element, a liquid crystal composition, and a compound containing a liquid crystal composition having a negative dielectric anisotropy. In particular, it relates to a liquid crystal display device using a liquid crystal composition containing an alignment monomer having a vinylene group in a part of the structure, and the liquid crystal can be achieved by the action of the compound. Molecular alignment.

液晶顯示元件中，基於液晶分子的運作模式的分類為相變（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。基於元件的驅動方式的分類為被動矩陣（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。TFT的分類為非晶矽（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。基於光源的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。In liquid crystal display elements, the operation modes based on liquid crystal molecules are classified into phase change (PC), twisted nematic (TN), super twisted nematic (STN), and electrically controlled birefringence ( electrically controlled birefringence (ECB), optically compensated bend (OCB), in-plane switching (IPS), vertical alignment (VA), fringe field switching (FFS), Field-induced photo-reactive alignment (FPA) and other modes. The component-based driving methods are classified into a passive matrix (PM) and an active matrix (AM). PM is classified as static, multiplex, etc. AM is classified as thin film transistor (TFT), metal-insulator-metal (MIM), and the like. TFTs are classified into amorphous silicon and polycrystal silicon. The latter is classified into a high temperature type and a low temperature type according to manufacturing steps. The classification based on the light source is a reflection type using natural light, a transmission type using backlight, and a semi-transmission type using both natural light and backlight.

液晶顯示元件含有具有向列相的液晶組成物。該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。將兩者的特性中的關聯歸納於下述表1中。基於市售的AM元件來對組成物的特性進一步進行說明。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。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影像（moving image），較佳為響應時間短。理想為短於1毫秒的響應時間。因此，較佳為組成物的黏度小。尤佳為低溫下的黏度小。The liquid crystal display element contains a liquid crystal composition having a nematic phase. This composition has appropriate characteristics. By improving the characteristics of the composition, an AM device having good characteristics can be obtained. The correlation between the characteristics of the two is summarized in Table 1 below. The characteristics of the composition will be further described based on a commercially available AM device. The temperature range of the nematic phase is related to the temperature range in which the element can be used. A preferred upper limit temperature of the nematic phase is about 70 ° C or higher, and a preferred lower limit temperature of the nematic phase is about -10 ° C or lower. The viscosity of a composition is related to the response time of the element. In order to display a moving image as a component, it is preferable that the response time is short. Ideally a response time shorter than 1 millisecond. Therefore, the viscosity of the composition is preferably small. Especially preferred is low viscosity at low temperatures.

[表1] [Table 1]

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，而需要大的光學各向異性或小的光學各向異性、即適當的光學各向異性。組成物的光學各向異性（Δn）與元件的單元間隙（cell gap）（d）的積（Δn×d）被設計成使對比度為最大。適當的積的值依存於運作模式的種類。VA模式的元件中，該值為約0.30 μm至約0.40 μm的範圍，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，對於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。組成物的大的介電各向異性有助於元件的低臨限電壓、小的電力消耗與大的對比度。因此，較佳為大的介電各向異性。組成物的大的比電阻有助於元件的大的電壓保持率與大的對比度。因此，較佳為在初始階段中，具有大的比電阻的組成物。較佳為在長時間使用後，具有大的比電阻的組成物。組成物相對於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。此種特性對於用於液晶監視器、液晶電視等的AM元件而言較佳。The optical anisotropy of the composition is related to the contrast of the element. Depending on the mode of the element, a large optical anisotropy or a small optical anisotropy is required, that is, an 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 to maximize the contrast. The value of the appropriate product depends on the type of operation mode. In the VA mode device, the value ranges from about 0.30 μm to about 0.40 μm, and in the IPS mode or FFS mode devices, the value ranges from about 0.20 μm to about 0.30 μm. In these cases, a composition having a large optical anisotropy is preferred for an element having a small cell gap. The large dielectric anisotropy of the composition contributes to the low threshold voltage of the device, small power consumption, and large contrast. Therefore, a large dielectric anisotropy is preferred. The large specific resistance of the composition contributes to the large voltage holding ratio and large contrast of the device. Therefore, a composition having a large specific resistance in the initial stage is preferred. A composition having a large specific resistance after long-term use is preferred. The stability of the composition with respect to ultraviolet rays and heat is related to the life 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 monitors and liquid crystal televisions.

具有TN模式的AM元件中使用具有正的介電各向異性的組成物。具有VA模式的AM元件中使用具有負的介電各向異性的組成物。具有IPS模式或FFS模式的AM元件中使用具有正或負的介電各向異性的組成物。 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。繼而，一邊對該元件的基板之間施加電壓，一邊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。該組成物中，可利用聚合體來控制液晶分子的配向，因此元件的響應時間縮短，圖像的殘像得到改善。於具有TN、ECB、OCB、IPS、VA、FFS、FPA之類的模式的元件中可期待聚合體的此種效果。 IPS模式、FFS模式、ECB模式中，於不對液晶分子施加電壓時，需要在相對於基板的主面而大致水平的方向上進行配向。為了實現此種液晶分子的配向控制，一直使用聚醯亞胺之類的配向膜。近年來，推進液晶面板的狹框緣化，配向膜與密封劑的接著寬度變窄，藉此存在如下情況：接著強度變弱，自配向膜與密封劑的界面進行剝離。為了防止此種問題，提出有不使用先前的聚醯亞胺之類的配向膜的方法（專利文獻1～專利文獻3）。A composition having a positive dielectric anisotropy is used for an AM device having a TN mode. A composition having a negative dielectric anisotropy is used for an AM device having a VA mode. A composition having a positive or negative dielectric anisotropy is used for an AM device having an IPS mode or an FFS mode. In a polymer sustained alignment (PSA) type liquid crystal display device, a liquid crystal composition containing a polymer is used. First, a composition to which a small amount of a polymerizable compound is added is injected into a device. Then, while applying a voltage between the substrates of the element, the composition was irradiated with ultraviolet rays. The polymerizable compound is polymerized to form a polymer network structure in the composition. In this composition, the polymer can be used to control the alignment of liquid crystal molecules, so the response time of the device is shortened, and the afterimage of the image is improved. Such an effect of a polymer can be expected in a device having a mode such as TN, ECB, OCB, IPS, VA, FFS, and FPA. In the IPS mode, FFS mode, and ECB mode, when no voltage is applied to the liquid crystal molecules, alignment needs to be performed in a direction substantially horizontal to the main surface of the substrate. In order to achieve such alignment control of liquid crystal molecules, alignment films such as polyimide have been used. In recent years, the narrow frame of the liquid crystal panel has been promoted, and the bonding width between the alignment film and the sealant has been narrowed. As a result, there is a case where the bonding strength is weak and the interface between the alignment film and the sealant is peeled. In order to prevent such a problem, a method is proposed in which an alignment film such as a polyimide is not used (Patent Literature 1 to Patent Literature 3).

報告有如下方法：代替聚醯亞胺之類的配向膜而使用具有肉桂酸酯基的低分子化合物或聚肉桂酸乙烯酯、具有查耳酮結構的低分子化合物、具有偶氮苯結構的低分子化合物或樹枝狀聚合物來控制液晶的配向（專利文獻1）。專利文獻1的方法中，首先，將該低分子化合物或聚合物以添加物的形式溶解於液晶組成物中。繼而，藉由使該添加物進行相分離而於基板上生成包含該低分子化合物或聚合物的薄膜。最後，於高於液晶組成物的上限溫度的溫度下對基板照射直線偏光。於低分子化合物或聚合物藉由該直線偏光而進行二聚化或異構化時，其分子在固定方向上進行排列。該方法中，藉由選擇低分子化合物或聚合物的種類而可製造IPS或FFS之類的水平配向模式的元件與VA之類的垂直配向模式的元件。該方法中，重要的是低分子化合物或聚合物容易於高於液晶組成物的上限溫度的溫度下溶解，恢復至室溫時，該化合物容易自液晶組成物中進行相分離。但是，難以確保低分子化合物或聚合物與液晶組成物的相容性。 專利文獻2及專利文獻3的方法中，將具有偶氮苯作為部分結構的樹枝狀聚合物以添加物的形式溶解於液晶組成物中。繼而，藉由使該化合物進行相分離而於基板上生成該化合物的薄膜。此時，液晶組成物相對於基板而垂直配向。繼而，不對基板進行加熱而照射直線偏光。於樹枝狀聚合物藉由該直線偏光而進行二聚化或異構化時，其分子在相對於基板而水平的方向上進行排列。可製造IPS或FFS之類的水平配向模式的元件。該方法中，亦為了使樹枝狀聚合物容易進行溶解與相分離，而必須適當組合樹枝狀聚合物與液晶組成物。於使用具有偶氮苯作為部分結構的樹枝狀聚合物的情況下，存在有源自偶氮苯的著色的問題。 專利文獻4中揭示有高分子分散型的液晶光學元件，其包含將手性向列液晶與具有二苯乙烯骨架的(甲基)丙烯酸酯系化合物光聚合而成的高分子樹脂。此處的液晶光學元件為減低驅動電壓與遲滯者。由於為將手性向列液晶設為必需成分，於未施加電壓時成為透明狀態或選擇反射狀態，於施加電壓時成為散射狀態的高分子分散型的液晶光學元件，因此與本申請案發明的構成不同。另外，亦不存在具有二苯乙烯骨架的(甲基)丙烯酸酯系化合物藉由偏光照射而引起液晶性化合物的水平配向等的暗示或記載。 [現有技術文獻] [專利文獻]The following methods are reported: instead of an alignment film such as polyimide, a low-molecular compound having a cinnamate group or a polyvinyl cinnamate, a low-molecular compound having a chalcone structure, Molecular compounds or dendrimers to control the alignment of liquid crystals (Patent Document 1). In the method of Patent Document 1, first, the low-molecular compound or polymer is dissolved in a liquid crystal composition as an additive. Then, the additive is subjected to phase separation to generate a thin film containing the low-molecular compound or polymer on the substrate. Finally, the substrate is irradiated with linearly polarized light at a temperature higher than the upper limit temperature of the liquid crystal composition. When a low molecular compound or polymer undergoes dimerization or isomerization by the linearly polarized light, its molecules are aligned in a fixed direction. In this method, by selecting the type of the low-molecular compound or polymer, an element in a horizontal alignment mode such as IPS or FFS and an element in a vertical alignment mode such as VA can be manufactured. In this method, it is important that the low-molecular compound or polymer is easily dissolved at a temperature higher than the upper limit temperature of the liquid crystal composition, and when it is returned to room temperature, the compound easily undergoes phase separation from the liquid crystal composition. However, it is difficult to ensure compatibility of the low-molecular compound or polymer with the liquid crystal composition. In the methods of Patent Documents 2 and 3, a dendritic polymer having azobenzene as a partial structure is dissolved in a liquid crystal composition as an additive. Then, a thin film of the compound is formed on the substrate by phase-separating the compound. At this time, the liquid crystal composition is aligned vertically with respect to the substrate. Then, linearly polarized light is irradiated without heating the substrate. When the dendrimer is dimerized or isomerized by the linearly polarized light, its molecules are aligned in a horizontal direction with respect to the substrate. Components can be manufactured in horizontal alignment modes such as IPS or FFS. In this method, in order to facilitate the dissolution and phase separation of the dendrimer, it is necessary to appropriately combine the dendrimer and the liquid crystal composition. When a dendrimer having azobenzene as a partial structure is used, there is a problem in that the coloring is derived from azobenzene. Patent Document 4 discloses a polymer-dispersed liquid crystal optical element including a polymer resin obtained by photopolymerizing a chiral nematic liquid crystal with a (meth) acrylate compound having a stilbene skeleton. The liquid crystal optical element here is a device that reduces the driving voltage and the hysteresis. Since a chiral nematic liquid crystal is an essential component, it is a polymer-dispersed liquid crystal optical element that is in a transparent state or a selective reflection state when no voltage is applied, and becomes a scattering state when a voltage is applied. different. In addition, there is no suggestion or description that the (meth) acrylic acid ester compound having a stilbene skeleton causes horizontal alignment of the liquid crystal compound by polarized light irradiation.

Furthermore, in order to realize a liquid crystal display element having excellent transmittance characteristics and contrast, an alignment monomer that exhibits good compatibility with a liquid crystal composition and is not colored is provided. [Means for solving problems]

本發明使用利用了液晶組成物的液晶顯示元件、液晶組成物及化合物，所述液晶組成物含有在部分結構中具有伸乙烯基的配向性單體而且具有負的介電各向異性。 [發明的效果]The present invention uses a liquid crystal display element, a liquid crystal composition, and a compound using a liquid crystal composition that contains an alignment monomer having a vinyl group in a partial structure and has negative dielectric anisotropy. [Effect of the invention]

根據本發明，藉由使用包含配向性單體的液晶組成物，可製造即便為狹框緣（narrow frame）亦難以剝離的液晶顯示元件。 另外，藉由使用對於液晶組成物的溶解性優異且無著色的配向性單體，可實現透過率特性或對比度優異的液晶顯示元件。 進而，液晶顯示元件的製造中，不需要配向膜的形成步驟，可削減液晶顯示元件的製造成本。According to the present invention, by using a liquid crystal composition containing an alignment monomer, a liquid crystal display element that is difficult to peel off even with a narrow frame can be manufactured. In addition, by using an alignment monomer having excellent solubility in a liquid crystal composition and no coloration, a liquid crystal display element having excellent transmittance characteristics and contrast can be realized. Furthermore, in the manufacturing of a liquid crystal display element, the formation step of an alignment film is not necessary, and the manufacturing cost of a liquid crystal display element can be reduced.

該說明書中的用語的使用方法為如下所述。有時將「液晶組成物」及「液晶顯示元件」的用語分別簡稱為「組成物」及「元件」。「液晶顯示元件」為液晶顯示面板及液晶顯示模組的總稱。「液晶性化合物」是具有向列相、層列相等液晶相的化合物，以及雖不具有液晶相，但出於調節向列相的溫度範圍、黏度、介電各向異性之類的特性的目的而混合於組成物中的化合物的總稱。該化合物具有例如1,4-伸環己基或1,4-伸苯基之類的六員環，且其分子結構為棒狀（rod like）。「聚合性化合物」是出於使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。The terminology used in this specification is as follows. The terms "liquid crystal composition" and "liquid crystal display element" may be simply referred to as "composition" and "element", respectively. "Liquid crystal display device" is a generic term for a liquid crystal display panel and a liquid crystal display module. A "liquid crystal compound" is a compound that has a nematic phase and a smectic liquid crystal phase, and although it does not have a liquid crystal phase, it is used to adjust the temperature range, viscosity, and dielectric anisotropy of the nematic phase A general term for compounds mixed in the composition. The compound has a six-membered ring such as 1,4-cyclohexyl or 1,4-phenylene, and its molecular structure is rod-like. The "polymerizable compound" is a compound added for the purpose of forming a polymer in the composition. The liquid crystal compound which has an alkenyl group is not polymerizable in the meaning.

液晶組成物是藉由將多種液晶性化合物混合來製備。向該組成物中視需要而添加光學活性化合物、抗氧化劑、紫外線吸收劑、色素、消泡劑、聚合性化合物、聚合起始劑、聚合抑制劑、極性化合物之類的添加物。即便於添加有添加物的情況下，液晶性化合物的比例亦是由基於不含添加物的液晶組成物的重量的重量百分率（重量%）來表示。添加物的比例是由基於不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。有時使用重量百萬分率（ppm）。聚合起始劑及聚合抑制劑的比例例外地基於聚合性化合物的重量來表示。The liquid crystal composition is prepared by mixing a plurality of liquid crystal compounds. To this composition, additives such as an optically active compound, an antioxidant, an ultraviolet absorber, a pigment, an antifoaming agent, a polymerizable compound, a polymerization initiator, a polymerization inhibitor, and a polar compound are added as needed. That is, when it is convenient to add an additive, the ratio of the liquid crystal compound is also expressed by a weight percentage (% by weight) based on the weight of the liquid crystal composition containing no additive. The ratio of the additive is expressed by a weight percentage (% by weight) based on the weight of the liquid crystal composition containing no 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. Sometimes parts per million by weight (ppm) is used. The ratio of the polymerization initiator and the polymerization inhibitor is exceptionally expressed based on the weight of the polymerizable compound.

有時將「向列相的上限溫度」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」。「比電阻大」是指組成物在初始階段中具有大的比電阻，而且在長時間使用後亦具有大的比電阻。「電壓保持率大」是指元件在初始階段中不僅於室溫下，而且於接近於上限溫度的溫度下亦具有大的電壓保持率，而且在長時間使用後不僅於室溫下，而且於接近於上限溫度的溫度下亦具有大的電壓保持率。為了對組成物或元件的特性進行研究，有時使用經時變化試驗。「提高介電各向異性」的表述於介電各向異性為正的組成物時，是指其值正向地增加，於介電各向異性為負的組成物時，是指其值負向地增加。The "upper limit temperature of the nematic phase" may be simply referred to as the "upper limit temperature". The "lower limit temperature of the nematic phase" may be simply referred to as the "lower limit temperature". "High specific resistance" means that the composition has a large specific resistance in the initial stage, and also has a large specific resistance after long-term use. "Large voltage retention" means that the element has a large voltage retention not only at room temperature in the initial stage, but also at a temperature close to the upper limit temperature, and not only at room temperature but also after It also has a large voltage holding ratio at a temperature close to the upper limit temperature. In order to investigate the characteristics of a composition or an element, a change with time is sometimes used. The expression "improving dielectric anisotropy" refers to a composition with a positive dielectric anisotropy, which means that its value increases positively, and a composition with a negative dielectric anisotropy means a negative value. Increase to the ground.

有時將式（1）所表示的化合物簡稱為「化合物（1）」。有時將選自式（1）所表示的化合物的群組中的至少一種化合物簡稱為「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。對於其他式所表示的化合物亦相同。「至少一個‘A’」的表述是指‘A’的數量為任意。「至少一個‘A’可經‘B’取代」的表述是指於‘A’的數量為一個時，‘A’的位置為任意，於‘A’的數量為兩個以上時，它們的位置亦可無限制地選擇。該規則亦適用於「至少一個‘A’經‘B’取代」的表述。The compound represented by formula (1) may be simply referred to as "compound (1)". At least one kind of compound selected from the group of compounds represented by formula (1) may be simply referred to as "compound (1)". "Compound (1)" means one compound, a mixture of two compounds, or a mixture of three or more compounds represented by formula (1). The same applies to compounds represented by other formulas. The expression "at least one" A "" means that the number of "A" is arbitrary. The expression "at least one 'A' may be replaced by 'B'" means that when the number of 'A' is one, the position of 'A' is arbitrary, and when the number of 'A' is two or more, their positions are You can also choose unlimitedly. This rule also applies to the expression "at least one 'A' is replaced by 'B'".

於該說明書中使用「至少一個-CH2 -可經-O-取代」之類的表述。該情況下，-CH2 -CH2 -CH2 -可藉由不鄰接的-CH2 -經-O-取代而轉換為-O-CH2 -O-。然而，鄰接的-CH2 -不會經-O-取代。這是因為該取代中生成-O-O-CH2 -（過氧化物）。即，該表述是指「一個-CH2 -可經-O-取代」與「至少兩個不鄰接的-CH2 -可經-O-取代」這兩者。該規則不僅適用於取代為-O-的情況，亦適用於取代為-CH=CH-或-COO-之類的二價基的情況。The expression "at least one -CH 2 -may be substituted with -O-" is used in this specification. In this case, -CH 2 -CH 2 -CH 2 -can be converted to -O-CH 2 -O- by non-adjacent -CH 2 -substituted with -O-. However, adjacent -CH 2 -will not be replaced by -O-. This is because -OO-CH 2- (peroxide) is formed during the substitution. That is, the expression refers to both "one -CH 2 -may be substituted with -O-" and "at least two non-adjacent -CH 2 -may be substituted with -O-". This rule applies not only when substituted with -O-, but also when substituted with a divalent group such as -CH = CH- or -COO-.

成分化合物的化學式中，將末端基R1 的記號用於多種化合物。該些化合物中，任意的兩個R1 所表示的兩個基可相同，或亦可不同。例如，有化合物（1-1）的R1 為乙基，且化合物（1-2）的R1 為乙基的情況。亦有化合物（1-1）的R1 為乙基，而化合物（1-2）的R1 為丙基的情況。該規則亦適用於其他末端基等的記號。式（1）中，於下標‘a’為2時，存在兩個環A。該化合物中，兩個環A所表示的兩個環可相同，或亦可不同。於下標‘a’大於2時，該規則亦適用於任意的兩個環A。該規則亦適用於Z1 、環D等記號。In the chemical formula of the component compound, the symbol of the terminal group R 1 is used for various compounds. In these compounds, the two groups represented by any two R 1 may be the same or different. For example, there may be a case where R 1 of the compound (1-1) is an ethyl group and R 1 of the compound (1-2) is an ethyl group. There are also cases where R 1 of compound (1-1) is ethyl and R 1 of compound (1-2) is propyl. This rule also applies to other terminal group marks. In formula (1), when the subscript 'a' is 2, there are two rings A. In this compound, the two rings represented by the two rings A may be the same or different. When the subscript 'a' is greater than 2, this rule also applies to any two rings A. This rule also applies to symbols such as Z 1 and ring D.

由六邊形包圍的A、B、C、D等記號分別與環A、環B、環C、環D等環相對應，且表示六員環、縮合環等環。式（3）中，橫切六邊形的一邊的斜線表示環上的任意氫可經-Sp1 -P1 等基取代。‘e’等下標表示經取代的基的數量。於下標‘e’為0（零）時，不存在此種取代。於下標‘e’為2以上時，於環F上存在多個-Sp1 -P1 。由-Sp1 -P1 所表示的多個基可相同，或亦可不同。Symbols A, B, C, and D surrounded by hexagons correspond to rings such as ring A, ring B, ring C, and ring D, respectively, and represent rings such as a six-membered ring and a condensed ring. In the formula (3), a diagonal line crossing one side of the hexagon indicates that any hydrogen on the ring may be substituted with a group such as -Sp 1 -P 1 . Subscripts such as 'e' indicate the number of substituted groups. When the subscript 'e' is 0 (zero), there is no such substitution. When the subscript 'e' is 2 or more, there are multiple -Sp 1 -P 1 on the ring F. The plural groups represented by -Sp 1 -P 1 may be the same or different.

2-氟-1,4-伸苯基是指下述兩種二價基。化學式中，氟可為朝左（L），亦可為朝右（R）。該規則亦適用於四氫吡喃-2,5-二基之類的藉由自環中去除兩個氫而生成的非對稱的二價基。該規則亦適用於羰基氧基（-COO-或-OCO-）之類的二價鍵結基。 2-Fluoro-1,4-phenylene refers to the following two divalent groups. In the chemical formula, fluorine may be leftward (L) or rightward (R). This rule also applies to asymmetric divalent groups such as tetrahydropyran-2,5-diyl, which are generated by removing two hydrogens from the ring. This rule also applies to divalent bonding groups such as carbonyloxy (-COO- or -OCO-).

液晶性化合物的烷基為直鏈狀或分支狀，不包含環狀烷基。直鏈狀烷基優於分支狀烷基。該些情況對於烷氧基、烯基等末端基亦相同。為了提高上限溫度，與1,4-伸環己基相關的立體構型是反式構型優於順式構型。The alkyl group of the liquid crystal compound is linear or branched, and does not include a cyclic alkyl group. Linear alkyl groups are preferred over branched alkyl groups. The same applies to terminal groups such as an alkoxy group and an alkenyl group. In order to raise the upper limit temperature, the stereo configuration associated with 1,4-cyclohexyl is a trans configuration that is better than a cis configuration.

認為具有伸乙烯基的配向性單體藉由照射紫外光而產生由自反式體向順式體的光異構化或二聚化所引起的環丁烷環的形成。可利用該性質來製備可使液晶分子配向的薄膜。 為了製備該薄膜，所照射的紫外線合適的是直線偏光。 首先，於將液晶性化合物的合計量設為100重量份時，將配向性單體以0.1重量份至10重量份的範圍添加於液晶組成物中，為了使配向性單體溶解，而對組成物進行加溫。將該組成物注入至不具有配向膜的元件中。繼而，一邊將元件加溫至向列相的上限溫度以上，一邊照射直線偏光，藉此促進配向性單體的光異構化或二聚化。光異構化的化合物或二聚化的化合物在固定方向上進行排列。同時，亦產生光聚合，於基板上形成薄膜。所形成的薄膜具有作為液晶配向膜的功能。It is considered that the alignment monomer having a vinyl group is irradiated with ultraviolet light to generate a cyclobutane ring caused by photoisomerization or dimerization of a trans-isomer to a cis-isomer. This property can be used to prepare a thin film capable of aligning liquid crystal molecules. In order to prepare the film, the ultraviolet rays to be irradiated are suitably linearly polarized light. First, when the total amount of the liquid crystal compound is 100 parts by weight, an alignment monomer is added to the liquid crystal composition in a range of 0.1 to 10 parts by weight. In order to dissolve the alignment monomer, the composition is adjusted. The material is warmed. This composition was injected into a device without an alignment film. Then, the element is heated to a temperature above the upper limit of the nematic phase, and linearly polarized light is irradiated to promote photoisomerization or dimerization of the alignment monomer.

The first step is to add an alignment monomer to the liquid crystal composition and heat the composition at a temperature higher than the upper limit temperature to dissolve the composition. The second step is to inject the composition into a liquid crystal display element. In this step, if the liquid crystal composition is heated and injected at a temperature higher than the upper limit temperature, the shear stress when the liquid crystal composition flows in the cell can be reduced, and the occurrence of alignment defects can be easily prevented. The third step is to irradiate the linearly polarized ultraviolet rays while heating the liquid crystal composition to a temperature higher than the upper limit temperature. The alignment monomer undergoes dimerization or isomerization by linearly polarized ultraviolet light, and also undergoes polymerization.

2.液晶分子的配向評價 ＜偏光曝光條件＞ 使用250 W的超高壓水銀燈（牛尾（Ushio）電機股份有限公司製造的多光源燈（Multi-Light））與線柵（wire grid）偏光板（毛特克（MOXTEK）公司製造的ProFlux（UVT-260A）），並照射3 mW/cm2 （使用牛尾（Ushio）電機股份有限公司製造的紫外線照度計UIT-150及UVD-S313來測定波長313 nm的照度）的強度的光。 實施例1 將配向性單體（A-1-1）以0.3重量份的比例添加於組成物（M1）中。於90℃（上限溫度以上）下將該混合物注入至不具有配向膜的IPS元件中。一邊於90℃（上限溫度以上）下對IPS元件進行加熱，一邊自法線方向對元件照射直線偏光的紫外線（313 nm、5.0 J/cm2 ），從而獲得形成有配向控制層的元件。所照射的紫外線通過偏振器，藉此成為直線偏光。繼而，將形成有配向控制層的元件設置於偏光顯微鏡上而對液晶的配向狀態進行觀察。偏光顯微鏡的偏振器與檢偏器以各自的透過軸正交的方式配置。首先，以液晶分子的配向方向與偏光顯微鏡的偏振器的透過軸成為平行的方式，即，以液晶分子的配向方向與偏光顯微鏡的偏振器的透過軸所形成的角度成為0度的方式，將元件設置於偏光顯微鏡的水平旋轉平台上。自元件的下側即偏振器側照射光，並觀察有無透過檢偏器的光。由於未觀察到透過檢偏器的光，因此配向判定為「良好」。再者，相同的觀察中，於觀察到透過檢偏器的光的情況下，配向判定為「不良」。繼而，使元件於偏光顯微鏡的水平旋轉平台上旋轉，並使偏光顯微鏡的偏振器的透過軸與液晶分子的配向方向所形成的角度自0度變化。確認到：透過檢偏器的光的強度隨著偏光顯微鏡的偏振器的透過軸與液晶分子的配向方向所形成的角度變大而增大，於其角度為45度時，大致成為最大。由以上所獲得的元件中，液晶分子在相對於元件的基板的主面而大致水平的方向上配向，且判定為「水平配向」。2. Orientation evaluation of liquid crystal molecules <Polarized light exposure conditions> A 250 W ultra-high pressure mercury lamp (Multi-Light manufactured by Ushio Electric Co., Ltd.) and a wire grid polarizer (hair ProFlux (UVT-260A) manufactured by MOXTEK Co., Ltd. was irradiated at 3 mW / cm 2 (Ultraviolet illuminance meter UIT-150 and UVD-S313 manufactured by Ushio Electric Co., Ltd. were used to measure a wavelength of 313 nm Intensity of light). Example 1 An alignment monomer (A-1-1) was added to the composition (M1) in a proportion of 0.3 parts by weight. This mixture was injected into an IPS device without an alignment film at 90 ° C (above the upper limit temperature). While heating the IPS element at 90 ° C. (above the upper limit temperature), the element was irradiated with linearly polarized ultraviolet rays (313 nm, 5.0 J / cm 2 ) from the normal direction to obtain an element having an alignment control layer formed thereon. The irradiated ultraviolet rays pass through a polarizer, thereby becoming linearly polarized light. Next, the element on which the alignment control layer was formed was set on a polarizing microscope to observe the alignment state of the liquid crystal. The polarizer and the analyzer of a polarizing microscope are arranged so that their respective transmission axes are orthogonal to each other. First, the alignment direction of the liquid crystal molecules is parallel to the transmission axis of the polarizer of the polarizing microscope, that is, the angle formed by the alignment direction of the liquid crystal molecules and the transmission axis of the polarizer of the polarizing microscope is 0 degrees. The element is set on a horizontal rotating platform of a polarizing microscope. Light was irradiated from the lower side of the element, that is, the polarizer side, and the presence or absence of light passing through the analyzer was observed. Since no light transmitted through the analyzer was observed, the alignment was judged to be "good". In addition, in the same observation, when the light transmitted through the analyzer is observed, the alignment is determined to be "bad". Then, the element is rotated on the horizontal rotating platform of the polarizing microscope, and the angle formed by the transmission axis of the polarizer of the polarizing microscope and the alignment direction of the liquid crystal molecules is changed from 0 degrees. It was confirmed that the intensity of the light transmitted through the analyzer increases as the angle formed by the transmission axis of the polarizer of the polarizing microscope and the alignment direction of the liquid crystal molecules increases, and becomes approximately maximum when the angle is 45 degrees. In the device obtained from the above, the liquid crystal molecules are aligned in a direction substantially horizontal to the main surface of the substrate of the device, and it is determined as "horizontal alignment".

An area where light does not pass through the analyzer is confirmed in the element, and an area where light passes through the analyzer is also confirmed. Alignment was judged to be poor.

3.配向性單體與液晶組成物的相容性 對所述實施例中所獲得的液晶組成物與配向性單體的混合物及所述比較例中所獲得的液晶組成物與聚合性化合物的混合物於室溫狀態下的穩定性進行評價。混合後，於100℃下變化為各向同性的液體並放置冷卻至25℃。於室溫下經過半日後確認有無析出，結果實施例1～實施例27、比較例2的混合物中未確認到析出，任一者的配向性單體的相容性良好。3. Compatibility of the alignment monomer and the liquid crystal composition with respect to the mixture of the liquid crystal composition and the alignment monomer obtained in the example and the liquid crystal composition and the polymerizable compound obtained in the comparative example. The stability of the mixture at room temperature was evaluated. After mixing, the solution was changed to an isotropic liquid at 100 ° C and left to cool to 25 ° C. After half a day at room temperature, the presence or absence of precipitation was confirmed. As a result, no precipitation was confirmed in the mixtures of Examples 1 to 27 and Comparative Example 2, and the compatibility of any of the alignment monomers was good.

根據表4可知，實施例1至實施例27中，雖改變了組成物或配向性單體的種類，但未觀察到漏光。當使用複數個配向性單體時情形亦有相同的傾向。該結果表示即便於元件中無聚醯亞胺之類的配向膜，配向亦良好，且所有的液晶分子亦在固定方向上進行排列。另一方面，於不含有配向性單體的比較例1中觀測到漏光。另外，不具有聚合性基的配向控制層形成化合物中，未獲得充分的配向性。 根據以上的結果，可知由具有兩個以上的聚合性基的配向性單體生成的薄膜對於液晶分子的配向均勻化而言發揮重要的作用。另外，可知與液晶組成物的相容性亦良好。 於其他配向性單體（例如，化合物（A-2-1-1）、化合物（A-2-2-1）、化合物（A-2-3）、化合物（A-2-4）、化合物（D-1-7）、化合物（D-1-8）、化合物（A-A-4）、化合物（A-A-13）、化合物（A-A-14）、化合物（A-A-15））的情況下，亦可期待相同的效果。 因此，若使用本發明的液晶組成物，則亦可期待獲得具有可使用元件的溫度範圍廣、響應時間短、電壓保持率高、臨限電壓低、對比度大、壽命長之類的特性的液晶顯示元件。 進而，亦可期待獲得具有如下液晶組成物的液晶顯示元件，所述液晶組成物於向列相的上限溫度高、向列相的下限溫度低、黏度小、光學各向異性適當、負的介電各向異性大、比電阻大、相對於紫外線的穩定性高、相對於熱的穩定性高之類的特性中，滿足至少一種特性。 [產業上之可利用性]As can be seen from Table 4, although the composition or the type of the alignment monomer was changed in Examples 1 to 27, no light leakage was observed. The same tendency occurs when a plurality of alignment monomers are used. This result indicates that even if an alignment film such as polyimide is not included in the device, the alignment is good, and all the liquid crystal molecules are aligned in a fixed direction. On the other hand, in Comparative Example 1 not containing an alignment monomer, light leakage was observed. In addition, in the alignment control layer-forming compound having no polymerizable group, sufficient alignment was not obtained. From the above results, it is understood that a thin film formed from an alignment monomer having two or more polymerizable groups plays an important role in uniformizing the alignment of liquid crystal molecules. Moreover, it turns out that compatibility with a liquid crystal composition is also favorable. For other alignment monomers (for example, compound (A-2-1-1), compound (A-2-2-1), compound (A-2-3), compound (A-2-4), compound (D-1-7), compound (D-1-8), compound (AA-4), compound (AA-13), compound (AA-14), compound (AA-15)), also The same effect can be expected. Therefore, if the liquid crystal composition of the present invention is used, a liquid crystal having characteristics such as a wide temperature range of usable elements, a short response time, a high voltage holding ratio, a low threshold voltage, a large contrast ratio, and a long life can be expected. Display element. Further, a liquid crystal display element having a liquid crystal composition having a high upper temperature in the nematic phase, a low lower temperature in the nematic phase, a low viscosity, a suitable optical anisotropy, and a negative dielectric material can also be expected. Among the characteristics such as large electrical anisotropy, large specific resistance, high stability to ultraviolet rays, and high stability to heat, at least one characteristic is satisfied.
