Definitions
- the present invention relates to a retardation plate and a method of manufacturing a retardation plate.
- the retardation film is widely used as a component of a display device such as a liquid crystal display device and an organic electroluminescence (hereinafter, sometimes referred to as “organic EL”) display device.
- a retardation plate is generally required to uniformly exhibit a desired retardation (for example, 1 ⁇ 4 wavelength or 1 ⁇ 2 wavelength) in a desired wavelength region (for example, the entire visible region).
- a retardation plate having a retardation of reverse wavelength dispersion has been developed as a retardation plate.
- the retardation of the inverse wavelength dispersion means a retardation showing a larger value for the transmitted light having a longer wavelength. That is, in a retardation plate having a retardation of reverse wavelength dispersion, the retardation of transmitted light at a long wavelength is larger than the retardation of transmitted light at a short wavelength.
- the retardation plate having such a reverse wavelength dispersive retardation can exhibit a desired value of retardation in a wide wavelength band, and thus can function uniformly in a wide wavelength band.
- the retardation plate having the reverse wavelength dispersion retardation is formed by combining a resin having a positive intrinsic birefringence value and a resin having a negative intrinsic birefringence value. What is manufactured is known.

- the resin whose retardation is drawn out of the resin having a positive intrinsic birefringence value and the resin having a negative intrinsic birefringence value is a letter plate. It is required to thicken as much as the foundation is pulled.
- the resin for which the retardation is drawn is required to have a predetermined amount of thickness so that the resin can exhibit an appropriate retardation capable of causing reverse wavelength dispersion in the retardation of the entire retardation plate. For this reason, it is difficult to make the retardation plate having the reverse wavelength dispersion retardation thinner than a certain limit as compared with another retardation plate made of a single resin.

- the resin having a negative intrinsic birefringence value means a resin having a refractive index in the stretching direction that is smaller than a refractive index in a direction perpendicular thereto.
- the intrinsic birefringence value can be calculated from the dielectric constant distribution.
- retardation means in-plane retardation.

第二層は、固有複屈折値が負の樹脂からなる層である。固有複屈折値が負の樹脂の種類に制限は無い。ただし、本発明の位相差板においては、厚みを薄くすることと所望のレターデーションを発現させることとの両方を達成する観点から、固有複屈折値が負の樹脂としては、結晶性の樹脂が好ましい。固有複屈折値が負の樹脂として結晶性の樹脂を用いることにより、当該結晶性の樹脂が含む結晶性の重合体を結晶化させたときに大きな複屈折を発現させられるので、薄い厚みの位相差板において高いレターデーションを得ることができる。
本発明の位相差板は、第一層と第二層との間に、第一層及び第二層を接着しうる第三層を備えることが好ましい。これにより、第一層と第二層との剥離を抑制できるので、本発明の位相差板の機械的強度を高めることができる。
本発明の位相差板は、上述した第一層、第二層及び第三層に加え、更に任意の層を備えうる。任意の層としては、例えば、帯電防止層、ハードコート層、及び汚染防止層等が挙げられる。
本発明の位相差板の波長450nmにおけるレターデーションRe(450)〔単位:nm〕、及び、本発明の位相差板の波長550nmにおけるレターデーションRe(550)〔単位:nm〕は、下記式(I)を満たす。
Re(450)/Re(550) < 0.92 (I)
Re(550)/d > 0.0035 (II)
本発明の位相差板の製造方法としては、上述した位相差板が得られる任意の方法を採用しうる。中でも、製造を効率良く行う観点から、本発明の位相差板は、
(a)固有複屈折値が正の樹脂及び固有複屈折値が負の樹脂を共押出して、固有複屈折値が正の樹脂からなる第一層及び固有複屈折値が負の樹脂からなる第二層を備える延伸前積層体を得る、第1の工程と;
(b)第1の工程の後で延伸前積層体を延伸して延伸体を得る、第2の工程と;
(c)第2の工程の後で、延伸体の固有複屈折値が正の樹脂及び固有複屈折値が負の樹脂の少なくとも一方の結晶化を促進させて、位相差板を得る第3の工程と;
を含む製造方法によって製造することが好ましい。
一般に、第一層のレターデーション、及び、第二層のレターデーションは、それぞれ、順波長分散性を示す。順波長分散性のレターデーションとは、より長波長の透過光についてより小さい値を示すレターデーションをいう。ここで、第一層及び第二層のうち、レターデーションが大きい方の層の順波長分散性が、レターデーションが小さい方の層の順波長分散性よりも小さい延伸体を想定する。このような延伸体では、レターデーションが大きい方の層は、短波長におけるレターデーションに比べ、長波長におけるレターデーションは大幅には低くならない。これに対し、レターデーションが小さい方の層は、短波長におけるレターデーションに比べ、長波長におけるレターデーションは大幅に低くなる。そのため、前記のように想定した延伸体では、短波長においては両層のレターデーションの差は小さく、長波長においては両層の間のレターデーションの差は大きいので、逆波長分散性のレターデーションが発現しうる。
本発明の位相差板の用途に特に制限は無く、任意の光学フィルムとして用いうる。例えば、本発明の位相差板は、液晶表示装置、有機EL表示装置等の表示装置用の光学補償フィルム;偏光板保護フィルム;などとして用いうる。特に、本発明の位相差板は、直線偏光子と組み合わせて円偏光板に用いることが好ましい。
〔重合体のラセモ・ダイアッドの割合の測定方法〕
オルトジクロロベンゼン-d4を溶媒として、150℃で、inverse-gated decoupling法を適用して、重合体の13C-NMR測定を行った。この13C-NMR測定の結果から、オルトジクロロベンゼン-d4の127.5ppmのピークを基準シフトとして、メソ・ダイアッド由来の43.35ppmのシグナルと、ラセモ・ダイアッド由来の43.43ppmのシグナルとの強度比に基づいて、重合体のラセモ・ダイアッドの割合を求めた。
位相差測定装置(王子計測器社製「KOBRA-WR」)を用いて、平行ニコル回転法により、位相差板のレターデーションReを測定した。この際、波長450nm及び波長550nmで入射角0°(位相差板の法線方向)において測定されたレターデーションを、それぞれ、Re(450)及びRe(550)とした。
各層の厚みを、位相差板断面の走査型電子顕微鏡(SEM)写真から計測した。次に、ドライエッチング装置(サムコ社製「RIE-10NE」)を使用して、位相差板の表面を第二層側からエッチングした。エッチング時間を10分から60分まで変化させたサンプルを数種類採取し、それぞれサンプルのレターデーションと厚みを測定した。レターデーションと厚みの変化分から、各層のレターデーションを算出した。
シミュレーション用のソフトウェアとしてシンテック社製「LCD Master」を用いて、各実施例及び比較例で製造された円偏光板をモデル化し、反射率を計算した。
シミュレーション用のモデルでは、平面状の反射面を有するミラーの前記反射面に、位相差板側でミラーに接するように円偏光板を貼り付けた構造を設定した。したがって、このモデルでは、厚み方向において、偏光フィルム、位相差板及びミラーがこの順に設けられた構造が設定された。
平面状の反射面を有するミラーを用意した。このミラーを、反射面が水平で且つ上向きになるように置いた。このミラーの反射面上に、偏光フィルム側が上向きになるように円偏光板を貼り付けた。
(i)極角0°、方位角0°の正面方向と、
(ii)極角45°、方位角0°~360°の傾斜方向と
の両方で行った。
この評価(i)及び(ii)を、評価が良好な方から順にA~Eの5段階で判定した。
金属製の耐圧反応器を、充分に乾燥した後、窒素置換した。この金属製耐圧反応器に、シクロヘキサン154.5部、ジシクロペンタジエン(エンド体含有率99%以上)の濃度70%シクロヘキサン溶液42.8部(ジシクロペンタジエンの量として30部)、及び1-ヘキセン1.9部を加え、53℃に加温した。
この触媒溶液を耐圧反応器に加えて、開環重合反応を開始した。その後、53℃を保ちながら4時間反応させて、ジシクロペンタジエンの開環重合体の溶液を得た。
得られたジシクロペンタジエンの開環重合体の数平均分子量(Mn)及び重量平均分子量(Mw)は、それぞれ、8,750および28,100であり、これらから求められる分子量分布(Mw/Mn)は3.21であった。

製造例1で製造したジシクロペンタジエンの開環重合体の水素添加物100部に、酸化防止剤(テトラキス〔メチレン-3-(3’,5’-ジ-t-ブチル-4’-ヒドロキシフェニル)プロピオネート〕メタン;BASFジャパン社製「イルガノックス(登録商標)1010」)1.1部を混合して、樹脂Aを得た。

前記の延伸前フィルムを、恒温槽付引っ張り試験機で自由一軸延伸して、延伸体としての延伸後フィルムを製造した(第2の工程)。この際の延伸条件は、下記の通りである。
・延伸温度:100℃
・延伸倍率:3倍
・延伸速度:3倍/1分
得られた延伸後フィルムは、波長450nmにおけるレターデーションRe(450)及び波長550nmにおけるレターデーションRe(550)が「Re(450)/Re(550)<0.92」を満たしていた。
前記の延伸後フィルムを50mm角に切り出し、その4辺をフレームで保持して、延伸後フィルムを緊張させた。このように延伸後フィルムを緊張させた状態で、この延伸後フィルムに加熱処理を施した(第3の工程)。この際の加熱条件は、処理温度180℃、処理時間2分であった。これにより、延伸後フィルム中の樹脂Aに含まれていたジシクロペンタジエンの開環重合体の水素添加物、及び、ポリスチレン樹脂に含まれていたポリスチレンの結晶化が進行して、厚み28μmの位相差板が得られた。得られた位相差板の各層及び全体のレターデーションを、上述した方法で測定した。
ヨウ素で染色した、ポリビニルアルコール樹脂製の長尺形状を有する樹脂フィルムを用意した。この樹脂フィルムを、当該樹脂フィルムの幅方向に対して90°の角度をなす長手方向に延伸して、長尺形状を有する偏光フィルムを得た。この偏光フィルムは、当該偏光フィルムの長手方向に吸収軸を有し、当該偏光フィルムの幅方向に偏光透過軸を有していた。
得られた円偏光板について、上述した方法で評価を行った。

前記工程(1-2)において、樹脂Aの代わりに非結晶性の環状オレフィンポリマーを含む樹脂(日本ゼオン社製「ZNR1215」)を用い、シンジオタクチック構造を有するポリスチレンを含むポリスチレン樹脂の代わりに非結晶性のスチレン-無水マレイン酸共重合体を含む樹脂(NovaChemicals社製「DylarkD332」)を用いた。

SMA:非結晶性のスチレン-無水マレイン酸共重合体を含む樹脂
反射率(i):円偏光板の正面方向の反射率。
反射率(ii):円偏光板の傾斜方向の反射率。
比較例1では所望のレターデーションが得られているものの、厚みを薄くできなかった。また、比較例2では、厚みを薄くしたことにより、所望のレターデーションが得られなかった。さらに、比較例3では、波長450nmにおいて所望のレターデーションが得られなかったので、位相差板はレターデーションの逆波長分散性に劣り、そのため円偏光板の反射防止性能に劣っていた。これに対し、実施例1及び2では良好な結果が得られている。この結果から、本発明により、逆波長分散性のレターデーションを有し且つ薄い位相差板を実現でき、それによって反射防止性能に優れる円偏光板を得られることが確認された。
