Abstract
本發明公開了一種液晶組合物,包含有一種或多種式Ⅰ化合物、一種或多種式Ⅱ所示化合物以及一種或多種式Ⅲ所示化合物,
Description
本發明涉及液晶顯示技術領域,具體涉及一種液晶組合物,以及包含該液晶組合物的液晶顯示元件或液晶顯示器。
在LCD的發展過程中,目前LCD用液晶向著回應速度更快,信賴性更好的方向發展,而液晶混合物的高速回應特性來源於其組分的相應物理參數,如旋轉黏度gamma1、彈性常數(K)等,高清晰點的單體也有助於混晶的組合搭配。由此可以看到,理想的液晶單體應具有低gamma1,高K,適當折射率,高清晰點等特徵。
為了實現這一特徵,在設計分子時會將烷氧基引入分子結構,通常來講,會將烷氧基與苯環相連接,以獲得高K,低黏度,寬的向列型溫度範圍等的特徵。
比如:
本發明,藉由液晶混合物搭配這一途徑,儘量克服烷氧基近晶的缺點,使之在商業液晶應用中成為可能,將會大幅度提高液晶的顯示速度。
本發明的目的是提供一種向列型液晶組合物,該組合物包含烷氧基類液晶以及其他液晶組合物,組分中存在烷氧基類液晶化合物。

對比例1中,相較於實施例1,將I組分-5BBO2替換為5BB1,Cp明顯下降,K11
由實施例1中24.8降低為對比例1中的14.9,折射率、旋轉黏度幾乎不變,回應速度變差,液晶相溫度範圍變窄。
由此可見,5BBO2較5BB1能夠明顯提高回應速度,擴寬液晶元件使用溫度範圍。
