PROBLEM TO BE SOLVED: To provide an organic EL display panel having a structure that efflux of ink hardly occurs, and also having stable quality.SOLUTION: An organic EL display panel 10 has a substrate 101, a first lower electrode 111 and a second lower electrode 121 which are disposed above the substrate 101 and aligned in a first direction X with a gap G placed therebetween, a first part 105F above the gap G, and a second part 105S which is adjacent to both the sides n the first direction X of the first part 105F, and located above the first lower electrode 111 or the second lower electrode 121, and also has a partition wall 105 which is shaped to partition the gap between the upper sides of the lower electrodes 111, 121, organic light emission layers 113, 123 which are respectively disposed above the lower electrodes 111, 121, and an upper electrode 107 disposed above the organic light emission layers 113, 123. At least a part of the bottom surface 105FB of the first part 105F is located to be higher than the bottom surface 105SB of the second part 105S.SELECTED DRAWING: Figure 4 【課題】インクの流出が発生しにくい構造を有し、品質が安定した有機ＥＬ表示パネルを提供する。【解決手段】基板１０１と、基板１０１の上方に配置され、第１方向Ｘに間隙Ｇをおいて並ぶ第１下部電極１１１及び第２下部電極１２１と、間隙Ｇの上方にある第１部分１０５Ｆと、第１部分１０５Ｆの第１方向Ｘ両側に隣接し、第１下部電極１１１の上方又は第２下部電極１２１の上方にある第２部分１０５Ｓと、を有し、下部電極１１１、１２１の各上方の間を仕切る形状であって、電気絶縁性材料からなる隔壁１０５と、下部電極１１１、１２１の各上方にそれぞれ配置された有機発光層１１３、１２３と、有機発光層１１３、１２３の上方に配置された上部電極１０７と、を備え、第１部分１０５Ｆの底面１０５ＦＢの少なくとも一部が、第２部分１０５Ｓの底面１０５ＳＢよりも高い位置にある有機ＥＬ表示パネル１０。【選択図】図４
