1312365 玖、發明說明: 【發明所屬之技術領域】 本發明有關一種液晶介質,其係以一種具有負型介電各 向異性之極性化合物的混合物為底質,其包括至少—種式j 之化合物: R1-(A1-z1)m
其中 R〇、R1 A' 係彼此獨立各為氫、最多具有15個碳原子之垸基 或烯基,其係未經取代或被CN或CF3單取代,或是 至少被鹵素早取代,此外,此等基團中之_或多 個 0^2基可以被-0-、_S---Ο ' -C.C- ^ -0C-0- 或-0-C0-置換,其置換方式係使氧原子不會直接 彼此鍵合, a) 係1,4·伸環己烯基或1,4-伸環己基 個非相鄰CH2基可以被-0·或置換 b) 係I,4-伸苯基,其中一或兩個CH基可被氮置賴 Ο係選自六氫^{4-二基、M.雙環[2·22]伸 f 二萘_2’6-二基、十氫莕_2,6·二基、1,2,3,“ 氣笨-2,6-二基、菲_2,7_二基與苟_2,7_二基, 其中’基團a)、b)與c)可被卣素原子單取:或多 Z1 係-c㈣…〇-CO〜CF2〇·、_〇CF2•、偶〇、〇叫、 -c2F4…CH2CF…CF :、 -CH2CH2-、-(ch2); 89298 1312365 -CF=CF-、-CH=CF-、-CF=CH-、-CH=CH-、-OC-或 一個單鍵,而 m 係0、1或2。 此種介質係特別用於以ECB效應為基礎之主動矩陣定址 的電光顯示器或是用於IPS (平面切換)顯示器。 【先前技術】 電控制雙折射之原理、ECB效應(電控雙折射)或DAP (配 向相變形)效應最早係於1971年提出(M.F. Schieckel與K. Fahrenschon之「具有垂直定向之向列液晶在電場中的變形 (Deformation of nematic liquid crystals with vertical orientation in electrical fields)」,Appl. Phys_ Lett. 19 (1971),3912)。然後是 J.F· Kahn (App-1. Phys. Lett. 20 (1972),1193)與 G. Labrunie與 J. Robert (J· Appl. Phys. 44 (1973),4869)所提出之論文。 J. Robert與 F. Clerc (SID 80 Digest Techn. Papers (1980),30)、 J. Duchene (Displays 7 (1986),3)與11.3(:1^€1(510 82 01层631丁6(±11·
Papers (1982),244)之論文已顯示液晶相必須具有高彈性係 數KVl比值、高光學各向異性值以及自_〇·5至-5之介電各 向異性Δε值,使其適用於以ECB效應為基礎之高資訊量顯 示器元件。以ECB效應為基礎之電光顯示器具有垂直邊緣配 向。負型介電液晶介質亦可用於使用所謂IPS效應之顯示 器。 .此種效應在電光顯示器元件之工業應用需要許多LC相, 其必須符合多項需求。此處特別重要的是對於濕氣、空氣 以及物理影響的耐化學性,諸如熱、在紅外線、可見光與 89298 1312365 ,于、夕卜系鱼γ㈤ %圍内之輻射’以及直流與交流電場。 卜可以工業應用之LC相必須在適當溫度範圍内且古 液晶中PE) 4 t U具有 τ間相與低黏度。 迄八 田 7已揭示之具有液晶中間相的一系列化合物中没有一 二I括苻合所有需求之單一化合物。因此,通常製備自9 2 25種化合物之混合物,自3至18種化合物之混合物為佳,- ^ Γ f仔可作為LC^S之物質。不過,由於迄今仍然没有具 明顯負型介電各向異性與適當長期安定性之液晶材料, 所以以此種方式仍然無法容易地製備最適相。 _ 目可已習知矩陣液晶顯示器(MLC顯示器)。可用以供個別 像素個別切換之非線性元件供係例如主動元恭曰 5# \ ,. 1 、1 咆曰曰 a 用主動矩陣」時’兩種類型的區別是: I以發晶圓作為基材上之MQS (金屬氧化物半導體) 2.以破璃板作為基材上之薄膜電晶體(TFT)。 ^ 在頜土 1田中,所使用之電光效應通常為動態散射或賓主 效應。由於各部件顯示器之偶數模組組合體會產生接頭處 <問題,故使用單晶石夕作 3 7作為基材材料會限制顯示器尺寸。 在更有潛力而且較佳乏相开丨〗1y丨丄 碩土 2 Λ例中,所使用之電光效應 通常為ΤΝ效應。 〜
兩種技術的區別是:包括I # π X g括數種化合物半導體之TFT,諸如 例如包括CdSe,或者以多曰 曰9夕或非晶相石夕為底質之TFT。目 前全世界均使用後一種技術。 將該TFT矩陣裝在該鞛千 ,.肩不备其中一片玻璃板内部,而另一 片玻璃板則將該透明斟啻iT非., 對%極載於其内部。與像素電極尺寸 89298 1312365 相較’ TFT非常小’而且實質對於影像沒有負面影響。此種 技術也可以擴展到全彩相容顯示器,其中將紅、綠及藍濾 波器的嵌鑲排列使遽波器元件位於每個可切換像素對面。 迄今所揭示之TF丁顯示器通常係以具有透射交叉偏振器 之TN構件操作,而且為後照光形式。 此處之MLC顯示器一辭涵蓋具有整合非線性元件之任何 矩陣顯示器’即,該主動矩陣除外,該辭亦涵蓋具有被動 元件之顯示器,此等被動元件係諸如變阻器或二極體 (MIM=金屬-絕緣體-金屬)。 ' 此種MLC顯示器特別適用於TV應用(例如,口袋型TV), 或是用於汽車或飛機構造之高資訊量顯示器。除了對比的 角度依存度與·反應時間等問題之外,由於液晶混合物之比 電阻不夠高,MLC顯示器中會出現許多困難。[TOGASHI,S., SEKIGUCHI, K., TANABE, H., YAMAMOTO, E., SORIMACHI, K., TAJIMA, E., WATANABE, H., SHIMIZU, H., Proc. Eurodisplay 84, Sept. 1984: A 210-288 Matrix LCD Controlled by Double Stage Diode Rings, pp. 141 ff., Paris; STROMER, M., Proc. Eurodisplay 84,Sept. 1984:Design of Thin Film Transistors for Matrix Addressing of Television Liquid Crystal Displays, pp. 145 ff., Paris]。隨著電阻降低,MLC顯示器的對比變差。由於與該 顯示器内部表面交互作用,該液晶混合物之比電阻通常 會隨著MLC顯示器使用壽命而降低,因此對於必須長時間 操作而且具有可接受電阻之顯示器而言,高(初始)電阻非 常重要。 89298 1312365 迄今所揭示之MLC-ΤΝ顯示器的缺點係其對比較低、視角 依存度相當高,以及在此等顯示器中製造濃淡度的困難度。 因此,仍然很需要具有高比電阻,同時操作溫度範圍廣、 反應時間短而且閥限電壓低之MLC顯示器,其中借助於該 低閥限電壓可以產生各種濃淡度。 【發明内容】 本發明目的係提出以ECB或IPS效應為基礎,而且沒有上 述缺點或是上述缺點最少,同時具有非常高比電阻值之 MLC顯示器。 __ 目前已發現,若此等顯示器元件中使用包括至少一種式I 化合物之向列液晶混合物可以達到此一目的。 因此,本發明有關一種以具有負型介電各向異性之極性 化合物之混合物為底質的液晶介質,此等極性化合物中包 括至少一種式I之化合物。 由例如EP 0 637 585 A1已習知式I之化合物。先前技術中 所述之液晶混合物僅希望用於鐵電應用。尚未知悉經氟化 1,2-二氫化茚在ECB或IPS顯示器中之用途。 本發明之混合物顯示非常適宜的電容閥限值、相當高之 保持比值,同時具有非常良好之低溫安定性以及非常低之 旋轉黏度。 下文表示一些較佳實例: a)液晶介質,其額外包括一或多種式IIA及/或IIB之化合物
