(環構造)
T→N :ネマチック相下限温度(℃)
Δn :20℃における屈折率異方性
Δε :20℃における誘電率異方性
γ1 :20℃における回転粘度(mPa・s)
K33 :20℃における弾性定数K33(pN)
応答速度 : VA型の液晶表示素子の20℃における応答速度を、オートロニック社製電気光学測定装置DMS703により測定した。
VHR(UV):高圧水銀ランプを用いて、365nmにおける照度が100mW/cm2の光を120秒照射した後の、周波数60Hz、印加電圧1V、60℃における電圧保持率(%)
焼き付き : 液晶表示素子の焼き付き評価は、表示エリア内に所定の固定パターンを任意の試験時間表示させた後に、全画面均一な表示を行ったときの固定パターンの残像が、許容できない残像レベルに達するまでの試験時間を計測した。
1)ここで言う試験時間とは固定パターンの表示時間を示し、この時間が長いほど残像の発生が抑制されており、性能が高いことを示している。
2)許容できない残像レベルとは、出荷合否判定で不合格となる残像が観察されるレベルである。
例)
サンプルA:1000時間
サンプルB:500時間
サンプルC:200時間
サンプルD:100時間
性能は、A>B>C>Dである。
液晶表示装置の滴下痕の評価は、全面黒表示した場合における白く浮かび上がる滴下痕を目視にて以下の5段階評価で行った。
4:滴下痕ごく僅かに有るも許容できるレベル(良)
3:滴下痕僅かに有り、合否判定のボーダーラインレベル(条件付で可)
2:滴下痕有り許容できないレベル(不可)
1:滴下痕有りかなり劣悪(悪)
低温でのネマチック相安定性 :
低温でのネマチック相安定性の評価は、組成物を調製後、2mLのサンプル瓶に組成物を1g秤量し、これに温度制御式試験槽の中で、次の運転状態「−20℃(1時間保持)→昇温(0.1℃/毎分)→0℃(1時間保持)→昇温(0.1℃/毎分)→20℃(1時間保持)→降温(−0.1℃/毎分)→0℃(1時間保持)→降温(−0.1℃/毎分)→−20℃」を1サイクルとして温度変化を与え続け、目視にて組成物からの析出物の発生を観察し、析出物が観察されたときの試験時間を計測した。
試験時間が長いほど長時間にわたって安定して液晶相を保っており、低温でのネマチック相安定性が良好である。
例)
サンプルA:24時間
サンプルB:120時間
サンプルC:48時間
サンプルD:240時間
性能は、D>B>C>Aである。
液晶材料の揮発性評価は、液晶組成物0.020gを1Paの環境下に90分放置したときの質量変化を評価した。
質量変化が小さいほど揮発しにくく、製造装置を汚染しないので、高性能であることを示す。
例)
サンプルA:0.019g
サンプルB:0.017g
サンプルC:0.018g
サンプルD:0.013g
性能は、A>C>B>Dである。
