Abstract

　上部電極と下部電極との間に有機層を介して流れるリーク電流を抑制する有機ＥＬ素子を提供する。有機ＥＬ素子（５１）は、バンク（３）で囲まれた画素領域（Ｒ１１）に形成されて少なくとも１層の発光層（６）を含む有機層（９）と、有機層（９）を挟んで形成された上部電極（７）及び下部電極（２）と、画素領域（Ｒ１１）とバンク領域（Ｒ１３）との間の境界領域（Ｒ１２）の上部電極（７）と下部電極（２）との間に形成され、画素領域（Ｒ１１）とバンク領域（Ｒ１３）との間の境界領域（Ｒ１２）の上部電極（７）と下部電極（２）との間に形成されたリーク電流ブロック層（５）とを備え、リーク電流ブロック層（５）の基板厚み方向における電気抵抗は、リーク電流ブロック層（５）と第１電極（２）との間に介在する有機層（９）の基板厚み方向における電気抵抗よりも大きい。
