Description
16 有機固体層
18 陰極
20 保護膜
50 有機TFT
100 有機EL素子
P 有機EL表示装置
本発明者は、無機膜に生じたピンホールを通じて水分、酸素、アウトガスなどの素子へダメージを与える成分が素子へ至ることを防止すべく検討を行った。その結果、驚くべきことに完全に酸化していない酸化前無機膜を形成した後、この酸化前無機膜を酸化させるとピンホールを埋め込むように酸化膜が生成し、ピンホールの幅を減少させ、時にはピンホールを完全に塞ぐ現象を見いだした。
以下、本発明の実施の形態を図面に基づいて説明する。なお、本実施形態については、本発明を実施するための一形態に過ぎず、本発明は本実施形態によって限定されるものではない。
基板10は、その構成する材料は適宜選択して用いればよい。例えば、樹脂としては、熱可塑性樹脂、熱硬化性樹脂、ポリカーボネート、ポリメタクリル酸メチル、ポリアリレート、ポリエーテルスルフォン、ポリサルフォン、ポリエチレンテレフタレートポリエステル、ポリプロピレン、セロファン、ポリカーボネート、酢酸セルロース、ポリエチレン、ポリ塩化ビニル、ポリスチレン、ポリアミド、ポリイミド、ポリ塩化ビニリデン、ポリビニルアルコール、エチレン・酢酸ビニル共重合体けん化物、フッ素樹脂、塩化ゴム、アイオノマー、エチレン・アクリル酸共重合体、エチレン・アクリル酸エステル共重合体等として様々な基板を用いることができる。また、樹脂を主成分とする基板ではなく、ガラス基板や、ガラスとプラスティックの貼り合せ基板、金属板であってもよく、また基板表面にアルカリバリア膜や、ガスバリア膜がコートされていてもよい。また、これら透明基板に反対側から光を射出するトップエミッション型である場合などには、基板10は必ずしも透明でなくともよい。
バリア膜12は本実施形態に限っては有機膜と無機膜を併用しているが無機膜のみであってもよい。バリア膜12を形成する場合には、材料は適宜選択して用いることができる。バリア膜12は保護膜の一つである。
図2には有機EL表示装置Pの有機EL素子100付近の拡大図が示される。有機EL素子100は、バリア膜12側から陽極14/有機固体層16/陰極18とから積層されて構成されている。
図3には、有機EL表示装置Pの有機TFT50付近の拡大図が示される。有機TFT50は、バリア膜12側からバリア膜12上に形成されたゲート電極52と、ゲート電極52の表面を覆うように形成されたゲート絶縁膜54とを有している。
封止膜20は本実施形態に限っては有機膜と無機膜を併用しているが無機膜のみであってもよい。封止膜は保護膜の一つである。
上述の有機EL表示装置Pの発光態様について説明する。
た電子は、発光層166へと輸送される。
本実施形態では保護膜の製造方法として、図4〜10で示されるバリア膜12の製造方法を例示して説明する。
