Abstract
【解決手段】本発明の有機電界発光素子100は、素子を構成する多数の構成要素の全体構造上部に多層構造の保護層10を形成して外部環境から構成要素を完全に隔離できる構造を有する。保護層10は、素子の構成要素上部に形成された有機物層11、有機物層上に形成された非有機物層12、及び非有機物層上に形成されたコーティング層13からなる。非有機物層上に形成されたコーティング層13は、窒化アルミチタン(TiAlN)等を用いる。
【選択図】 図2
Description
非有機物層12上に形成されたコーティング層13の材料は、オキサイド系の窒化アルミチタン(TiAlN)であり、スパッタリング工程またはe−ビーム方式によって形成される。このコーティング層13が全体構造上部に形成されることで非有機物層12、有機物層11及び素子の構成要素Eは外部環境と完全に隔離される。
一方、素子100の作動のためには電源が印加され、電源によって導電性材料からなる構成要素Eに静電気が発生しうる。発生された静電気は構成要素Eに帯電され素子100の機能に影響を与えることができ、激しい場合、素子100自体が損傷される恐れがある。
