Description

光學機能薄膜
本發明涉及光學機能薄膜。
近年來，對影像顯示裝置要求亮度、鮮豔度(即廣色域化)，而有機EL顯示裝置(OLED)備受矚目，從而對液晶顯示裝置亦同樣尋求廣色域化。舉例而言，作為使液晶顯示裝置等影像顯示裝置廣色域化之方法，有文獻提出一種將於特定波長範圍內展現吸收極大波長的色彩校正濾光片配置於影像顯示裝置之視辨側的方法(專利文獻1)。然而，在以往之方法中，有因色彩校正濾光片吸收光而發生的亮度降低之問題、含有色素的色彩校正濾光片會隨時間褪色之耐久性問題等。

發明效果 根據本發明，可提供一種光學機能薄膜，該光學機能薄膜可有助於影像顯示裝置之廣色域化，且可抑制亮度降低並具優異耐久性。
用以實施發明之形態 以下說明本發明之較佳實施形態，惟本發明不受該等實施形態限定。
A.光學機能薄膜 圖1(a)係本發明之一實施形態的光學機能薄膜的概略截面圖。本實施形態之光學機能薄膜100具備光學機能層10。光學機能層10之透濕度為100g/m2 以下。上述光學機能層10於580nm~610nm之範圍的波長帶區域具有吸收峰。所述光學機能層可藉由使該光學機能層含有預定之色素而製得。光學機能薄膜除了光學機能層之外，亦可具備任意適當之構件。例如，光學機能薄膜可如後述具備黏著劑層、基材等。
圖1(b)係本發明之另一實施形態的光學機能薄膜的概略截面圖。本實施形態之光學機能薄膜100’於光學機能層10之至少單側更具備黏著劑層20。圖1(c)係本發明之又另一實施形態的光學機能薄膜的概略截面圖。本實施形態之光學薄膜100’’於光學機能層10之至少單側更具備基材30。代表上，光學機能層10與基材30係透過黏著劑層20來積層。
本發明中，係使用後述之特定色素(通式(I)或(II)所示色素)，使上述光學機能層選擇性吸收特定波長範圍(580nm~610nm)的光，並抑制其在該特定波長範圍以外的波長範圍中進行不需要的吸收，藉此可製得可有助於影像顯示裝置之廣色域化及高亮度化的光學機能薄膜。只要使用本發明之光學機能薄膜，即使不使用高成本之技術(有機EL技術、量子點技術)，仍可使影像顯示裝置顯著地廣色域化。且，使光學機能層之透濕度為100g/m2 以下，可使該光學機能層之耐久性優異，而即使如上述為了形成具有光吸收特性的光學機能層而使用色素，仍可抑制色素褪色(分解)，從而可歷時性穩定地維持廣色域化。本發明的成果之一係可將耐久性低的上述色素使用於光學機能薄膜。在光學機能薄膜具備黏著劑層等其他層時，不使該其他層含有該色素，而使透濕度低的光學機能層含有該色素，可獲得本發明之效果。
A-1.光學機能層 如上述，上述光學機能層於580nm~610nm之範圍的波長帶區域具有吸收峰。只要形成所述光學機能層，即可製得可有助於影像顯示裝置之廣色域化及高亮度化的光學機能薄膜。此外，吸收光譜可利用分光光度計(股份有限公司日立High-Technologies製，製品名「U-4100」)測定。
上述光學機能層在波長580nm~610nm中之最大吸收峰值的吸光度Amax 、與在波長545nm之吸光度A545 的比(A545 /Amax )宜為0.13以下，更宜為0.12以下，且0.11以下更佳，0.1以下尤佳。依上所述，只要形成在波長545nm中吸光度小的光學機能層，即可吸收在色彩表現上不需要的光，而可製得可有助於影像顯示裝置之廣色域化的光學機能薄膜。又，由於不易吸收來自光視效能高的545nm左右之光源的發光，因此可減少亮度降低之情形。
上述光學機能層之位於波長580nm~610nm之範圍內的吸收峰之半值寬度宜為35nm以下，且30nm以下更佳，25nm以下又更佳，20nm以下尤佳。只要在所述範圍內，即可製得可有助於影像顯示裝置之廣色域化的光學機能薄膜。
在一實施形態中，上述光學機能層於530nm~570nm之範圍內不具有吸收峰。更具體而言，上述光學機能層於530nm~570nm之範圍內不具有吸光度在0.1以上的吸收峰。只要形成所述光學機能層，即可製得可有助於影像顯示裝置之廣色域化的光學機能薄膜。
在一實施形態中，上述光學機能層更於440nm~510nm之範圍的波長帶區域具有吸收峰。即，在本實施形態中，上述光學機能層於440nm~510nm及580nm~610nm之範圍的波長帶區域具有吸收峰。只要為所述構成，即可良好地防止紅色光與綠色光混色、以及綠色光與藍色光混色。只要將依所述方式構成之光學機能薄膜應用於影像顯示裝置，即可使影像顯示裝置廣色域化，而可獲得明亮且鮮豔的畫質。如上所述具有2個以上之吸收峰的光學機能層可藉由使用多種色素來製得。
光學機能層在吸收峰下之透射率宜為0%~80%，更宜為0%~70%。若為所述範圍內，本發明之上述效果便更明顯。
上述光學機能層的可見光透射率宜為30%~90%，且較宜為30%~80%。只要在所述範圍內，即可製得可在抑制亮度降低的同時使影像顯示裝置廣色域化的光學機能薄膜。
如上述，上述光學機能層之透濕度為100g/m2 以下。光學機能層之透濕度宜為90g/m2 以下，更宜為80g/m2 以下，又更宜為70g/m2 以下。光學機能層之透濕度越低越好，惟其下限例如為0.5g/m2 。另，本說明書中所謂「透濕度」係指依據JIS Z0208之透濕度試驗(透濕杯法(cup method))，於溫度40℃、濕度92%RH之氣體環境中，測定在24小時內通過面積1m2 之試料的水蒸氣量(g)所得之值。
光學機能層之厚度通常為0.1μm~100μm，以1μm~100μm為宜，以2μm~50μm為佳，以5μm~35μm更佳。
述光學機能層可由含有樹脂與色素之樹脂組成物形成。
