Abstract
Description
1)誘電率(ε‖)の測定:よく洗浄したガラス基板にオクタデシルトリエトキシシラン(0.16mL)のエタノール(20mL)溶液を塗布した。ガラス基板をスピンナーで回転させたあと、150℃で1時間加熱した。2枚のガラス基板の間隔(セルギャップ)が4μmであるVA素子に試料を入れ、この素子を紫外線で硬化する接着剤で密閉した。この素子にサイン波(0.5V、1kHz)を印加し、2秒後に液晶分子の長軸方向における誘電率(ε‖)を測定した。
2)誘電率(ε⊥)の測定:よく洗浄したガラス基板にポリイミド溶液を塗布した。このガラス基板を焼成した後、得られた配向膜にラビング処理をした。2枚のガラス基板の間隔(セルギャップ)が9μmであり、ツイスト角が80度であるTN素子に試料を注入した。この素子にサイン波(0.5V、1kHz)を印加し、2秒後に液晶分子の短軸方向における誘電率(ε⊥)を測定した。
Δφ(deg.)=φ(after)−φ(before) (式2)
これらの測定はJ. Hilfiker, B. Johs, C. Herzinger, J. F. Elman, E. Montbach, D. Bryant, and P. J. Bos, Thin Solid Films, 455-456, (2004) 596-600を参考に行った。Δφが小さいほうが液晶配向軸の変化率が小さく、液晶配向軸の安定性が良いといえる。
