Description
[有機EL表示装置の電極構成]
図1は、画素の第一電極の平面図である。画素1は、R画素、G画素、B画素の3つの副画素を有している。各副画素の第一電極4は第一画素電極2と第二画素電極3とを有している。第一画素電極2と隣接する副画素の第一画素電極2との間には、第二画素電極3が配置されている。例えば、G画素の第一画素電極2GとB画素の第一画素電極2Bとの間には、第二画素電極3G及び第二画素電極3Bが配置されている。各第一電極上には不図示の有機EL層が複数の画素に亘って共通層として設けられている。共通層とは、平面内において分離されることなく形成されている層である。
図4は、本発明の有機EL表示装置に用いられる画素回路の一例である。図4において、副画素10は、有機EL素子11と、有機EL素子11を駆動する駆動回路とによって構成されている。有機EL素子11は、11aと11bとに分けて記載されている。有機EL素子11は全副画素10に対して共通に設けられた第二電極18が接続されている。第二電極はカソード電極であってよい。有機EL素子11の第一電極である、アノード電極は、副画素毎に2つに分割されているため有機EL素子11a、有機EL素子11bと表すことができる。有機EL素子11aは、第一画素電極に電流を供給する回路であり、有機EL素子11bは第二画素電極に電流を供給する回路である。
図6は、本実施形態に係る画素の平面図である。本実施形態は、特定の副画素の第一電極のみが、第一画素電極及び第二画素電極を有し、その他の副画素の第一電極は分割されていないことを除いて、第一の実施形態と同じである。第一の実施形態の構造及び説明は本実施形態においても同様に適用することが可能である。
図7は、本実施形態に係る画素の平面図である。本実施形態は、同じ色を発光する副画素の第一画素電極同士の間には、第二画素電極を設けないことを除いて、第一の実施形態と同じである。実施例1の構造及び説明は本実施例においても同様に適用することが可能である。
本発明に係る表示装置は、基板を有してよい。基板は、高い強度を有する基板であっても、フレキシブル基板であってもよい。具体的には、ガラス基板、シリコン基板等の強度が高い基板であってよい。また、ポリアクリル基板、ポリイミド基板等のフレキシブル基板であってよい。
