Description
本発明は、硬化膜形成組成物、配向材および位相差材に関する。 The present invention relates to a cured film forming composition, an alignment material, and a retardation material.
近年、液晶パネルを用いたテレビ等のディスプレイの分野においては、高性能化に向けた取り組みとして、3D画像を楽しむことができる3Dディスプレイの開発が進められている。3Dディスプレイでは、例えば、観察者の右目に右目用画像を視認させ、観察者の左目に左目用画像を視認させることにより、立体感のある画像を表示させることができる。 In recent years, in the field of displays such as a television using a liquid crystal panel, development of a 3D display capable of enjoying 3D images has been promoted as an effort toward high performance. In the 3D display, for example, a right-eye image is visually recognized by an observer's right eye, and a left-eye image is visually recognized by an observer's left eye, whereby a stereoscopic image can be displayed.
3D画像を表示する3Dディスプレイの方式には多様なものがあり、専用のメガネを必要としない方式としては、レンチキュラレンズ方式およびパララックスバリア方式等が知られている。
そして、観察者がメガネを着用して3D画像を観察するディスプレイの方式の1つとしては、円偏光メガネ方式等が知られている(例えば、特許文献1を参照。)。There are various 3D display methods for displaying 3D images, and lenticular lens methods, parallax barrier methods, and the like are known as methods that do not require dedicated glasses.
And as one of the display systems in which an observer wears glasses and observes a 3D image, a circularly polarized glasses system or the like is known (see, for example, Patent Document 1).
円偏光メガネ方式の3Dディスプレイの場合、液晶パネル等の画像を形成する表示素子の上にパターニングされた位相差材が配置されるのが通常である。このパターニングされた位相差材は、位相差特性の異なる2種類の位相差領域がそれぞれ複数、規則的に配置されることにより構成される。尚、以下、本明細書においては、このような位相差特性の異なる複数の位相差領域を配置するようにパターニングされた位相差材をパターン化位相差材と称する。 In the case of a circularly polarized glasses type 3D display, a patterned retardation material is usually disposed on a display element that forms an image, such as a liquid crystal panel. The patterned retardation material is configured by regularly arranging a plurality of two kinds of retardation regions having different retardation characteristics. Hereinafter, in the present specification, a retardation material patterned so as to arrange a plurality of retardation regions having different retardation characteristics is referred to as a patterned retardation material.
パターン化位相差材は、例えば、特許文献2に開示されるように、重合性液晶からなる位相差材料を光学パターニングすることで作製することができる。重合性液晶からなる位相差材料の光学パターニングは、液晶パネルの配向材形成で知られた光配向技術を利用する。すなわち、基板上に光配向性の材料からなる塗膜を設け、これに偏光方向が異なる2種類の偏光を照射する。そして、液晶の配向制御方向の異なる2種類の液晶配向領域が形成された配向材として光配向膜を得る。この光配向膜の上に重合性液晶を含む溶液状の位相差材料を塗布し、重合性液晶の配向を実現する。その後、配向された重合性液晶を硬化してパターン化位相差材を形成する。 For example, as disclosed in Patent Document 2, the patterned retardation material can be produced by optically patterning a retardation material made of a polymerizable liquid crystal. Optical patterning of a retardation material made of a polymerizable liquid crystal utilizes a photo-alignment technique known for forming an alignment material for a liquid crystal panel. That is, a coating film made of a photo-alignment material is provided on a substrate, and two types of polarized light having different polarization directions are irradiated on the coating film. Then, a photo-alignment film is obtained as an alignment material in which two types of liquid crystal alignment regions having different liquid crystal alignment control directions are formed. A solution-like retardation material containing a polymerizable liquid crystal is applied on the photo-alignment film to realize the alignment of the polymerizable liquid crystal. Thereafter, the aligned polymerizable liquid crystal is cured to form a patterned retardation material.
液晶パネルの光配向技術を用いた配向材形成では、利用可能な光配向性の材料として、側鎖にシンナモイル基およびカルコン基等の光二量化部位を有するアクリル樹脂やポリイミド樹脂等が知られている。これらの樹脂は、偏光UV照射することにより、液晶の配向を制御する性能(以下、液晶配向性とも言う。)を示すことが報告されている(特許文献3〜特許文献5を参照。)。 In the formation of alignment materials using the photo-alignment technology of liquid crystal panels, acrylic resins and polyimide resins having photodimerization sites such as cinnamoyl groups and chalcone groups in the side chain are known as usable photo-alignment materials. . It has been reported that these resins exhibit the ability to control the alignment of liquid crystal (hereinafter also referred to as liquid crystal alignment) by irradiation with polarized UV (see Patent Documents 3 to 5).
しかしながら、本発明者らの検討によれば、こうした側鎖にシンナモイル基やカルコン基等の光二量化部位を有するアクリル樹脂は、位相差材の形成に適用した場合に充分な特性(配向感度)が得られないことが分かっている。特に、これらの樹脂に偏光UVを照射して配向材を形成し、その配向材を用いて重合性液晶からなる位相差材料の光学パターニングをするためには、大きな偏光UV露光量が必要となる。その偏光UV露光量は、通常の液晶パネル用の液晶を配向させるのに十分な偏光UV露光量(例えば、100mJ/cm2程度。)より格段に多くなる。However, according to the study by the present inventors, an acrylic resin having a photodimerization site such as a cinnamoyl group or a chalcone group in the side chain has sufficient characteristics (orientation sensitivity) when applied to the formation of a retardation material. I know I can't get it. In particular, in order to form an alignment material by irradiating these resins with polarized UV and to perform optical patterning of a retardation material composed of a polymerizable liquid crystal using the alignment material, a large amount of polarized UV exposure is required. . The polarized UV exposure amount is much larger than the polarized UV exposure amount (for example, about 100 mJ / cm 2 ) sufficient to align the liquid crystal for a normal liquid crystal panel.
偏光UV露光量が多くなる理由としては、位相差材形成の場合には液晶パネル用の液晶と異なり、重合性液晶が溶液の状態で用いられ、配向材の上に塗布されることが挙げられている。 The reason why the amount of polarized UV exposure increases is that, in the case of forming a retardation material, different from the liquid crystal for a liquid crystal panel, a polymerizable liquid crystal is used in a solution state and applied onto an alignment material. ing.
具体的には、側鎖にシンナモイル基等の光二量化部位を有するアクリル樹脂等を用いて配向材を形成し、該配向材を用いて重合性液晶を配向させようとする場合、まずアクリル樹脂等において光二量化反応による光架橋が行われる。そして、重合性液晶溶液に対する耐性が発現するまで、大きな露光量の偏光照射を行う必要がある。
一方、液晶パネルの液晶を配向させるためには、通常、光配向性の配向材の表面のみを二量化反応させればよい。
しかし、上述のアクリル樹脂等の従来材料を用いて配向材に重合性液晶溶液に対する耐性(溶剤耐性)を発現させようとすると、配向材の内部まで反応を進行させる必要があり、より多くの露光量が必要となる。その結果、従来材料の配向感度は非常に小さくなってしまうという問題があった。Specifically, when an alignment material is formed using an acrylic resin or the like having a photodimerization site such as a cinnamoyl group in the side chain, and an attempt is made to align the polymerizable liquid crystal using the alignment material, the acrylic resin or the like is first used. The photocrosslinking is carried out by photodimerization reaction. And it is necessary to irradiate polarized light with a large exposure amount until resistance to the polymerizable liquid crystal solution is developed.
On the other hand, in order to align the liquid crystal of the liquid crystal panel, it is usually sufficient to dimerize only the surface of the photo-alignment alignment material.
However, if the alignment material is to be made resistant to the polymerizable liquid crystal solution (solvent resistance) using a conventional material such as the above-mentioned acrylic resin, it is necessary to advance the reaction to the inside of the alignment material, and more exposure. A quantity is required. As a result, there is a problem that the orientation sensitivity of the conventional material becomes very small.
また、上述の従来材料である樹脂にこのような溶剤耐性を発現させるため、架橋剤を添加する技術が知られている。しかし、架橋剤による熱硬化反応を行った後、形成される塗膜の内部には3次元構造が形成され、光反応性が低下することがわかっている。すなわち従来材料に架橋剤を添加して使用しても、結果として配向感度が大きく低下してしまい、所望とする効果は得られていない。 In addition, a technique of adding a crosslinking agent is known in order to develop such solvent resistance in the above-described conventional resin. However, it has been found that after a thermosetting reaction with a crosslinking agent, a three-dimensional structure is formed inside the formed coating film and the photoreactivity is lowered. That is, even when a crosslinking agent is added to a conventional material, the orientation sensitivity is greatly reduced as a result, and a desired effect is not obtained.
以上より、配向材の配向感度を向上させ、偏光UV露光量を低減できる光配向技術と、その配向材の形成に用いられる硬化膜形成組成物が求められている。そして、高効率にパターン化位相差材を提供することができる技術が求められている。 From the above, there is a need for a photo-alignment technique that can improve the alignment sensitivity of an alignment material and reduce the amount of polarized UV exposure, and a cured film forming composition used for the formation of the alignment material. And the technique which can provide a patterned phase difference material with high efficiency is calculated | required.
また、光配向技術を用いて3Dディスプレイのパターン化位相差材を製造する場合、従来はガラス基板上での形成がなされてきた。しかし、近年は製造コスト低減の要求に応じ、TAC(トリアセチルセルロース)フィルム、COP(シクロオレフィンポリマー)フィルムなどの安価な樹脂フィルム上で、所謂ロールツーロールにより生産されることが求められている。 Moreover, when manufacturing the patterned phase difference material of 3D display using a photo-alignment technique, it has conventionally been formed on a glass substrate.

As used herein, the term “aliphatic polyamide” can refer to aliphatic polyamides, aliphatic copolyamides, and blends or mixtures thereof.
こうして得られるポリアミドや、市販のポリアミドを、例えば、T.L.Cairnsら(J.Am.Chem.Soc.,71,P651(1949))が提案するような方法で、アミド結合の窒素原子Nにアルコキシメチル基またはアルキルチオメチル基を導入することができる。 Polyamides thus obtained and commercially available polyamides can be synthesized by, for example, a method such as proposed by TLCairns et al. (J. Am. Chem. Soc., 71, P651 (1949)) to the nitrogen atom N of the amide bond with alkoxymethyl. Groups or alkylthiomethyl groups can be introduced.
例えば、ポリアミドのギ酸溶液に、ホルマリンのアルコールまたはメルカプタン溶液を作用させた後、水/アセトン混合液などの貧溶媒中に注ぎ、アンモニアで中和することによって変性ポリアミドの沈澱物が生じる。また、工業的には、上記ポリアミドに、高温、高圧下でりん酸触媒を用いて、直接にホルマリンとアルコールまたはメルカプタンを作用させることにより、変性ポリアミドを作製することができる。ポリアミドの窒素原子Nの置換度が進むにつれて、樹脂の結晶性、融点、弾性率は低下し、溶解性、柔軟性は増大する。置換度は、反応条件によって広範囲で選択することができるが、本発明においては、置換度が10〜50モル%、好ましくは20〜40モル%のものが用いられる。この置換領域のものが、最もアルコールに可溶で、溶液状態での安定性がよい。10モル%より低いものは、溶剤溶解性や密着性、および体積抵抗率において特性を満足することができない。他方、置換度が50モル%より高くなると、反応条件設定が困難になる。アミド結合の窒素原子の置換基の種類は、変性反応に用いる溶剤によって選択することができ、アルコールを用いる場合は、例えば、メトキシメチル基、エトキシメチル基、イソブトキシメチル基等を有するものが得られ、メルカプタンを用いる場合は、例えば、エチルチオメチル基、イソブチルチオメチル基等を有するものが得られる。この上記変性ポリアミド樹脂のアミド結合の窒素原子を置換した極性基の機能により、得られる樹脂の溶解度を向上させることができる。 For example, a formalin alcohol or mercaptan solution is allowed to act on a polyamide formic acid solution, which is then poured into a poor solvent such as a water / acetone mixture and neutralized with ammonia to form a modified polyamide precipitate. Further, industrially, a modified polyamide can be produced by allowing formalin and alcohol or mercaptan to act directly on the polyamide using a phosphoric acid catalyst at high temperature and high pressure. As the degree of substitution of the nitrogen atom N in the polyamide proceeds, the crystallinity, melting point and elastic modulus of the resin decrease, and the solubility and flexibility increase. The degree of substitution can be selected in a wide range depending on the reaction conditions. In the present invention, the degree of substitution is 10 to 50 mol%, preferably 20 to 40 mol%. Those in this substitution region are most soluble in alcohol and have good stability in solution. If the content is lower than 10 mol%, the solvent solubility, adhesion, and volume resistivity cannot satisfy the characteristics. On the other hand, when the degree of substitution is higher than 50 mol%, it is difficult to set reaction conditions. The type of the substituent of the nitrogen atom of the amide bond can be selected depending on the solvent used for the modification reaction. When an alcohol is used, for example, one having a methoxymethyl group, an ethoxymethyl group, an isobutoxymethyl group or the like is obtained. In the case of using mercaptan, for example, those having an ethylthiomethyl group, an isobutylthiomethyl group or the like can be obtained. The solubility of the resulting resin can be improved by the function of the polar group in which the nitrogen atom of the amide bond of the modified polyamide resin is substituted.

It can be used properly according to the phase difference.
また、3Dディスプレイに用いられるパターン化位相差材を製造する場合には、本実施形態の硬化膜組成物から上記した方法で形成された硬化膜に、ラインアンドスペースパターンのマスクを介して所定の基準から、例えば、+45度の向きで偏光UV露光し、次いで、マスクを外してから−45度の向きで偏光UVを露光し、液晶の配向制御方向の異なる2種類の液晶配向領域が形成された配向材を得る。その後、重合性液晶溶液からなる上述の位相差材料を塗布した後、液晶の相転移温度まで加熱することで位相差材料を液晶状態とし、配向材上で配向させる。そして、配向状態となった位相差材料をそのまま硬化させ、位相差特性の異なる2種類の位相差領域がそれぞれ複数、規則的に配置された、パターン化位相差材を得ることができる。 Moreover, when manufacturing the patterned phase difference material used for 3D display, it is predetermined | prescribed via the mask of a line and space pattern to the cured film formed by the above-mentioned method from the cured film composition of this embodiment. For example, polarized UV exposure is performed in a +45 degree direction from the reference, and then the polarized UV light is exposed in a -45 degree direction after removing the mask, and two types of liquid crystal alignment regions having different liquid crystal alignment control directions are formed. To obtain an alignment material. Then, after apply | coating the above-mentioned phase difference material which consists of a polymeric liquid crystal solution, it heats to the phase transition temperature of a liquid crystal, makes a phase difference material a liquid crystal state, and aligns it on an orientation material. Then, the retardation material in an oriented state is cured as it is, and a patterned retardation material in which a plurality of two types of retardation regions having different retardation characteristics are regularly arranged can be obtained.
また、上記のようにして形成された、本実施の形態の配向材を有する2枚の基板を用い、スペーサを介して両基板上の配向材が互いに向かい合うように張り合わせた後、それらの基板の間に液晶を注入して、液晶が配向した液晶表示素子とすることもできる。
このように、本実施の形態の硬化膜形成組成物は、各種位相差材(位相差フィルム)や液晶表示素子等の製造に好適に用いることができる。Further, after using the two substrates having the alignment material of the present embodiment formed as described above, the alignment materials on both the substrates are bonded to each other through a spacer, and then the substrates A liquid crystal display element in which the liquid crystal is aligned can also be obtained by injecting liquid crystal therebetween.
