Description
更に、補助電極3は第1の電極取り出し端子7を通して一電源に接続するようになっている。同様に、上記対向電極6の端部が第2の電極取り出し端子として他電源につながるようになっている。そして、封止部材8により全体が気密封止されている。
ここで、発光面となる透明電極2以外に配設される補助電極3(あるいは3a)の配線幅は50μm以上であっても構わない。第1の電極取り出し端子7から近い部分は配線抵抗を低減させるために太くなっているとよい。

Claims (3)
- 一対の対向する電極間に少なくとも有機発光層を含む正方形パターンの有機EL層が挟持された有機EL素子において、
前記一対の対向電極の一電極より低抵抗の補助電極が前記一電極に電気的に接続され、
前記補助電極は、複数の配線群からなる電極配線であり、かかる電極配線は、相互に交差する配線パターンを有し、
前記一電極面上において前記有機EL層の膜厚の薄い領域よりも前記膜厚の厚い領域に、前記補助電極が高い密度に配設されていることを特徴とする有機EL素子。 - 前記補助電極は、前記一電極面上の配線群から成ることを特徴とする請求項1に記載の有機EL素子。
- 前記一電極は透光性材料から成り、前記補助電極はその配線幅が50μmを超えないことを特徴とする請求項2に記載の有機EL素子。
