Description
(A)分子中にグリシジル基を有する化合物:100重量部
(B)酸無水物硬化剤:50〜150重量部
を主成分とする有機EL素子封止材を見いだした。
各硬化性樹脂を厚み150μmのシート状に加工し硬化させ(硬化条件:表1参照)、60℃×95%の条件で透湿度を測定した。(使用機器:L80−5000型水蒸気透過度計/LYSSY社製)表中単位はg/m2x24hである。
評価2:アウトガス測定
フッ素樹脂コートした板の上に各硬化性樹脂を約20mg計量し所定の硬化条件で硬化させ、ダブルショットパイロライザーおよびガスクロマトグラフ/質量分析計(GC/MS)を用いたダイナミックヘッドスペース法で120℃×15分加熱した際に発生するアウトガス量を測定した。表中単位はppmである。
評価3:透過率測定
パネル用ガラス基板を25mm×50mmにカットし、ガラス片が十字状になるように中央に樹脂を挟み(50μm)所定の硬化条件で硬化させた。これを分光高度計で400nmの透過性を測定し、硬化性樹脂を塗布しないガラスのみのものをブランクとして、透過率を測定した。表中単位は%である。
評価4:パネル信頼性試験(ダークスポット評価)
ガラス基板上にスパッタリングにより透明電極を0.1μmの厚みで成膜した。続いて、透明電極の上部に正孔輸送層及び有機物EL層を0.05μmの厚みで順次成膜した。また有機物EL層の上部に背面電極を0.2μmの厚みで成膜する。これらの素子の成膜を終えた後、ガラス基板1の上部に各硬化性樹脂をEL素子材として約0.1mmの厚みで滴下し、この硬化性樹脂の上から非透水性ガラス基板を密着させた(硬化条件:表1参照)。このようにして有機ELパネルを作製し、連続点灯で60℃、90%の環境でダークスポットの成長を観察した。1000時間経過後の直径100μm以上のダークスポットが発生したものはD、2000時間経過後に直径100μm以上のダークスポットが発生したものはC、同様に3000時間はB、4000時間経過しても直径100μm以上のダークスポットが発生していないものはAとした。これらの結果を表2に示した。

3正孔輸送層
4有機物EL層
5背面電極
6非透水性ガラス基板
7有機EL素子封止材
Claims (2)
- ガラスもしくはフィルム基板1上に透明電極2、正孔輸送層3、有機物EL層4及び背面電極5からなる有機EL層を形成し、有機EL素子封止材7により透明電極2、正孔輸送層3、有機EL層4及び背面電極5の積層を覆う様に、該基板1と非透水性ガラスもしくはフィルム6を貼り合わせる有機EL素子に用いられる有機EL封止材であって、(A)〜(C)成分からなる有機EL素子封止材。
(A)成分 水分が800ppm以下の分子中にグリシジル基を有する化合物:100重量部
(B)成分 水分除去工程直後の水分が1200ppm以下のメチルヘキサヒドロ無水フタル酸:50〜150重量部
(C)成分 硬化促進剤:0.1〜10重量部 - 前記有機EL素子封止材に、さらに(D)成分としてカップリング剤を添加する請求項1に記載の有機EL素子封止材。
