Description
Rin=d×(nx-ny)
高分子フィルム基板の面内位相差値(Rin)は、Agilent社のUV/VISスペクトロスコープ8453装備を利用して下記方法によって550nm波長の光に対して測定した。UV/VISスペクトロスコープに2枚の偏光子を透過軸が互いに直交するように設置し、前記2枚の偏光子の間に高分子フィルムの遅相軸が2枚の偏光子の透過軸とそれぞれ45度をなすように設置した後、波長による透過度を測定した。波長による透過度グラフにおいて各ピーク(peak)の位相遅延次数(Phase retardation order)を求める。具体的に、波長による透過度グラフにおいて波形は、下記数式Aを満たし、サイン(Sine)波形で最大ピーク(Tmax)条件は、下記数式Bを満たす。数式Aでλmaxである場合、数式AのTと数式BのTは同一であるので、数式を展開する。n+1、n+2およびn+3に対しても数式を展開し、nとn+1数式を整理してRを消去してnをλnおよびλn+1数式で整理すると、下記数式Cが導き出される。数式AのTと数式BのTが同一であることに基づいてnとλを知ることができるので、各λn、λn+1、λn+2およびλn+3に対してRを求める。4ポイントに対して波長によるR値の直線トレンドラインを求め、数式550nmに対するR値を算定する。直線トレンドラインの関数は、Y=ax+bであり、aおよびbは、定数である。前記関数のxに550nmを代入したときのY値が550nm波長の光に対するRin値である。
T=sin2[(2πR/λ)]
T=sin2[((2n+1)π/2)]
n=(λn-3λn+1)/(2λn+1+1-2λn)
高分子フィルム基板の弾性率(Young's modulus)、伸び率(Elongation)および最大応力(Max.stress)は、UTM(Universal Testing Machine)装備(Instron 3342)を利用して、常温(25℃)で10mm/minの引張速度で力を加えて、規格によって引張強度(tensile strength)試験を進めて測定した。この場合、各試験片は、幅が約10mmであり、長さが約30mmとなるようにカットして製造し、前記長さ方向の両終端の各10mmずつをテーピングして装備に固定した後に評価を進めた。
前記SRF基板を2つ使用して光変調デバイスを製造した。前記SRF基板(横:15cm、縦:5cm)のITO(Indium Tin Oxide)膜(電極層)上に配向膜を形成して、第1基板を製造した。配向膜としては、厚さ300nmのポリイミド系水平配向膜(SE-7492,Nissan)をラビング布でラビング処理したものを使用した。第1基板と同一に第2基板を製造した。前記第1および第2基板を相互の配向膜が対向するように対向配置し、それらの間に屈折率異方性△nが0.13である正の誘電率異方性を有する液晶化合物および二色性染料を含むGHLC混合物(MDA-16-1235、Merck)にキラルドーパント(S811、Merck)を約0.519重量%の濃度で配合した組成物を位置させた後に、周縁部を封止して、光変調フィルム層を製造した。前記で第1および第2基板のTD方向(遅相軸方向)は、それぞれ、第1基板配向膜のラビング軸を基準として0度となり、前記第1および第2配向膜のラビング方向は、互いに90度をなすようにした。得られた光変調層は、ねじれ角(twisted angle)が約270度であるSTNモード液晶層であり、セルギャップは12μmであった。前記光変調フィルム層を電圧の無印加時の直進光透過率が約28.0%であり、約15Vの電圧を印加した場合に、直進光透過率が約62.7%であって、透過および遮断モードの間をスイッチング可能なデバイスである。前記で透過率は、NDH5000SP(SECOS社製)装備を使用した透過率であって、約550nm波長の光に対する透過率である。
基板としてPC基板を適用したことを除いて、実施例1と同一に光変調デバイスを製造した。
前記実施例1および比較例1の光変調デバイスを使用して図8および図9に示された形態のアイウェア素子を製造し、前記素子をベンディングさせた状態で熱衝撃試験を進めた。熱衝撃試験は、前記アイウェアを約-40℃から90℃まで約16.25℃/分の昇温速度で温度を上げた後、10分間維持し、さらに約16.25℃/分の減温速度で90℃から-40℃の温度まで減温した後、10分間維持することを1サイクルとして、前記サイクルを500回繰り返す条件に置いた状態で進め、この試験は、曲率半径が約100R程度である曲げ治具に前記アイウェアを付着した状態で進めた。図8は、実施例1の場合であり、図9は、比較例1の場合であり、図面のように比較例1の場合、激しいクラックが観察された。
実施例1と同一に光変調フィルム層を製造するものの、第1および第2基板の第1方向(TD方向)が互いに90度となるようにした。この際、第1基板上の配向膜のラビング方向を基準として第1基板の第1方向は0度、第2基板の第1方向は90度となるようにした。
実施例1と同一に光変調フィルム層を製造するものの、第1および第2基板の第1方向(TD方向)が互いに90度となるようにした。この際、第1基板上の配向膜のラビング方向を基準として第1基板の第1方向は45度、第2基板の第1方向は135度となるようにした。
実施例1、比較例2および3のデバイスをそれぞれ60℃の温度および85%の相対湿度で保管しつつ、ボイド発生を評価し、その結果を下記表2に記載した。具体的に前記条件で保管しつつ、光変調層において目視で視認されるボイドが発生するか否かを評価した。一般的に、目視で視認されるボイドのサイズは、約10μm程度である。
図4の構造の光変調デバイスを製造した。第1~第4高分子フィルム基板31、33、34、36として、前記SRF基板を使用した。前記SRF基板のITO膜上に垂直配向膜(HANCHEM社のPVM-11ポリイミド層)を形成し、光変調層としては、液晶および二色性染料を含むゲストホスト液晶層を用意するものの、前記液晶としては、HCCH社のHNG730200(ne:1.551、no:1.476、ε∥:9.6、ε⊥:9.6、TNI:100、△n:0.075、△ε:-5.7)を用意し、前記二色性染料としては、BASF社のX12を用意した。
実施例2において、第1基板の第1方向(TD方向、遅相軸方向)を0度というとき、第2および第3基板の第1方向(TD方向、遅相軸方向)が90度となるように配置したことを除いて、実施例1と同じ方法で光変調デバイスを製造した。
実施例2において第1光変調層の水平配向時の光軸が+45度となるように変更し、第2光変調層の水平配向時の光軸を-45度となるように変更したことを除いて、実施例1と同じ方法で光変調デバイスを製造した。
実施例2~4のデバイスに対して、正面(傾斜角0度)および視野角(傾斜角-23度)でレインボー特性および電気光学特性を評価し、その結果を図面と下記表3に記載した。
