T→N :ネマチック相となる相転移温度
Δn :298Kにおける屈折率異方性
no :
Δε :298Kにおける誘電率異方性
ε⊥ :
γ1 :298Kにおける回転粘度
Vth :厚さ8.5ミクロンのTNセルに液晶を封入し、298K、クロスニコル偏光板下において透過率が10%変化する電圧。
耐熱試験後VHR:組成物サンプルを封入した電気光学特性評価用TEG(テスト・エレメント・グループ)を130℃の恒温槽中に1時間保持した後、上述のVHR測定方法と同条件で測定した。
液晶組成物を、TN用液晶セル(セルギャップ8.3μm)に真空注入し、UV硬化性樹脂(スリーボンド社製、Three Bond 3026)で封止し、液晶セルを作製した。
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)
プロセス適合性 :
プロセス適合性は、ODFプロセスにおいて、定積計量ポンプを用いて、液晶を1回に50pLずつ「0〜100回、101〜200回、201〜300回、・・・・」と100回ずつ滴下したときの各100回滴下分の液晶の質量を計測し、質量のバラつきがODFプロセスに適合できない大きさに達した滴下回数で評価した。
滴下回数が多いほど長時間にわたって安定的に滴下可能であり、プロセス適合性が高いといえる。
例)
サンプルA:95000回
サンプルB:40000回
サンプルC:100000回
サンプルD:10000回
性能は、C>A>B>Dである。
低温での保存性評価は、組成物を調製後、1mLのサンプル瓶に組成物を0.5g秤量し、これを−25℃の温度制御式試験槽の中で240時間保存して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。析出発生までの試験時間が長いほど低温での保存性が良好であるといえる。
液晶材料の揮発性評価は、真空攪拌脱泡ミキサーの運転状態をストロボスコープを用いて観察し、液晶材料の発泡を目視により観察することによって行った。具体的には、容量2.0Lの真空攪拌脱泡ミキサーの専用容器に組成物を0.8kg入れ、4kPaの脱気下、公転速度15S−1、自転速度7.5S−1で真空攪拌脱泡ミキサーを運転し、発泡が始まるまでの時間を計測した。
発泡が始まるまでの時間が長いほど揮発しにくく、製造装置を汚染する可能性が低いので、高性能であることを示す。
例)
サンプルA:200秒
サンプルB:45秒
サンプルC:60秒
サンプルD:15秒
性能は、A>C>B>Dである。
