Description

可聚合化合物、液晶組合物、液晶顯示元件及液晶顯示器 Polymerizable compound, liquid crystal composition, liquid crystal display element and liquid crystal display

本發明屬於液晶顯示技術領域，具體涉及一種可聚合化合物、包含該可聚合化合物的液晶組合物，以及包含有該可聚合化合物或液晶組合物的液晶顯示元件或液晶顯示器。 The invention belongs to the field of liquid crystal display technology, and in particular relates to a polymerizable compound, a liquid crystal composition containing the polymerizable compound, and a liquid crystal display element or a liquid crystal display containing the polymerizable compound or the liquid crystal composition.

隨著顯示技術的發展，液晶顯示元件(Liquid Crystal Display，LCD)等平面顯示裝置因具有高畫質、省電、機身薄及應用範圍廣等優點，而被廣泛的應用於手機、電視、個人數位助理、數位相機、筆記型電腦、台式電腦等各種消費性電子產品，成為顯示裝置中的主流。 With the development of display technology, liquid crystal display (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, TVs, Various consumer electronic products such as personal digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices.

反應性液晶(Reactive Mesogen,RM)目前是液晶顯示行業非常熱門且重要的研究方向，其可能應用的領域包括聚合物穩定配向(PSA)液晶顯示，聚合物穩定藍相(PS-BP)液晶顯示以及圖形化位元相差膜(Pattern Retarder Film)等。 Reactive liquid crystal (Reactive Mesogen, RM) is currently a very popular and important research direction in the liquid crystal display industry.

但是，液晶化合物與RM混合後在PSA模式顯示器中的應用方面仍具有一些缺點。首先，到目前為止並不是所有RM都適合用於PSA顯示器；同時，如果採用紫外光(Ultraviolet light)而不添加光引發劑使RM進行聚合，則能夠選擇RM種類變得更少；另外，要求液晶化合物與所選擇的RM組合形成的液晶組合物具有優良的擴散性。在液晶化合物與RM混合後，需要進行10 天左右的低溫測試，因此需要RM有很好的低溫溶解性。 However, the application of liquid crystal compounds mixed with RMs in PSA mode displays still has some disadvantages. First of all, not all RMs are suitable for PSA displays so far; at the same time, if the RMs are polymerized using Ultraviolet light without adding a photoinitiator, fewer RM types can be selected; in addition, the requirements The liquid crystal composition formed by combining the liquid crystal compound with the selected RM has excellent diffusivity. After the liquid crystal compound is mixed with the RM, 10 Low temperature test of about 10 days, so RM has good low temperature solubility.

為了克服反應性液晶(RM)低溫溶解度差和擴散性差的問題，獲得具有低溫溶解性好和擴散性均勻的液晶組合物，本發明人等進行了深入研究，發現通過在液晶組合物中含有本發明的化合物能夠解決該問題，藉以完成了本發明。 In order to overcome the problems of poor low-temperature solubility and poor diffusivity of reactive liquid crystals (RM), and to obtain a liquid crystal composition with good low-temperature solubility and uniform diffusivity, the present inventors have conducted in-depth research and found that by including the liquid crystal composition in the liquid crystal composition The inventive compound can solve this problem, thereby completing the present invention.

做為本發明的液晶顯示器的製備方法，本領域具有通常知識者能夠根據本領域的常識選擇合適的方法進行製備。做為本發明的液晶顯示器的製備方法的一個例子，例如，包括下述步驟的製備方法： As the preparation method of the liquid crystal display of the present invention, those skilled in the art can select an appropriate method for preparation according to common knowledge in the field. As an example of the preparation method of the liquid crystal display of the present invention, for example, the preparation method comprising the following steps:

在第一基板和第二基板的表面均勻塗布配向材料，配向材料可以選用聚醯亞胺，對均勻塗布的配向材料進行加熱固化，加熱溫度為210-250℃，形成配向層；在第二基板表面散佈間隔物，並沿第一基板的邊緣塗布邊框膠，並在100℃-150℃下進行固化；將第一基板和第二基板相對設置，貼合形成具有夾層空間的結構；將液晶組合物注入第一基板和第二基板之間的夾層空 間，密封固化，藉以將液晶組合物密封在第一基板和第二基板之間，並同時進行加電、紫外光照射。紫外光照射分為第一階段紫外光照射(UV1)、第二階段紫外光照射(UV2)的兩個階段。在UV1階段，紫外光波長為360nm-370nm，紫外光輻照度為60-72mw/cm2。做為紫外光照射的時間，可以為例如50-65s，較佳為50-60s。 Evenly coat the alignment material on the surface of the first substrate and the second substrate. The alignment material can be polyimide, and heat and cure the evenly coated alignment material at a heating temperature of 210-250°C to form an alignment layer; on the second substrate Spread spacers on the surface, apply frame glue along the edge of the first substrate, and cure it at 100°C-150°C; set the first substrate and the second substrate oppositely, and form a structure with a sandwich space; combine the liquid crystal The liquid crystal composition is injected into the interlayer space between the first substrate and the second substrate, sealed and solidified, so as to seal the liquid crystal composition between the first substrate and the second substrate, and simultaneously carry out electrification and ultraviolet light irradiation. The ultraviolet light irradiation is divided into two stages of the first stage ultraviolet light irradiation (UV1) and the second stage ultraviolet light irradiation (UV2). In the UV1 stage, the wavelength of ultraviolet light is 360nm-370nm, and the irradiance of ultraviolet light is 60-72mw/cm 2 . The time for ultraviolet light irradiation may be, for example, 50-65s, preferably 50-60s.

在第一階段的光照射結束後進行第二階段光照射(UV2)，UV2中所使用的光可以列舉出例如紫外光。第二階段紫外光照射(UV2)紫外光波長例如為360nm-370nm，在UV2階段使用紫外光輻照度為例如3-8mw/cm2。通過採用這樣的輻照度，能夠使得未發生聚合的式I所示化合物緩慢的完全聚合，提高可聚合化合物的轉化率，藉以使得液晶組合物中不存在可聚合化合物的殘留。並且由於聚合緩慢，該過程不會對已經形成的預傾角產生影響。UV2階段的紫外光照射時間可以為例如100-150min。 The second-stage light irradiation (UV2) is performed after the first-stage light irradiation is completed, and the light used in UV2 includes, for example, ultraviolet light. In the second stage of ultraviolet irradiation (UV2), the wavelength of ultraviolet light is, for example, 360nm-370nm, and the irradiance of ultraviolet light used in the UV2 stage is, for example, 3-8mw/cm 2 . By adopting such irradiance, the unpolymerized compound represented by formula I can be slowly and completely polymerized, and the conversion rate of the polymerizable compound can be improved, so that there is no residue of the polymerizable compound in the liquid crystal composition. And because the polymerization is slow, the process has no effect on the pretilt angle already formed. The ultraviolet light irradiation time in the UV2 stage can be, for example, 100-150 min.
