Description
tin oxide)等からなる複数のライン状の陽極と、この各陽極と直交するアルミニウム(Al)等からなる複数のライン状の陰極との間に少なくとも発光層を有する有機層を形成してなる有機EL素子を透光性の基板上に設けてなるドットマトリクス型の有機ELパネルが知られている(例えば特許文献1参照)。かかる有機EL素子は、前記陽極から正孔を注入し、また、前記陰極から電子を注入して正孔及び電子が前記発光層にて再結合することによって光を発するものである。また、前記有機EL素子は、前記陰極側から前記陽極側へは電流が流れにくい、いわゆるダイオード特性を有するものである。

Claims (3)
- 一対の電極間に少なくとも発光層を有する有機層を積層形成してなる有機EL素子を基板上に設けてなる有機ELパネルであって、
前記有機EL素子として、正孔輸送性材料を少なくとも含むホスト材料を有する共通発光層と前記共通発光層上に形成され前記共通発光層とは異なる発光色を示す異色発光層とを有する第一の有機EL素子と、前記共通発光層と前記共通発光層上に形成され前記正孔輸送性材料を少なくとも含むホスト材料を有し前記共通発光層と同じ発光色を示す同色発光層とを有する第二の有機EL素子と、を隣接して形成してなることを特徴とする有機ELパネル。 - 前記同色発光層は、前記正孔輸送性材料の濃度が前記共通発光層と異なるように形成されてなることを特徴とする請求項1に記載の有機ELパネル。
- 前記第一の有機EL素子は白色発光を呈することを特徴とする請求項1に記載の有機ELパネル。
