Organic el display panel and method of manufacturing organic el display panel

A method of manufacturing an organic EL display panel, comprising:

• forming a plurality of first electrodes that are spaced away from each other and are arrayed in rows and columns above a substrate;
• forming a plurality of light-emitting layers that include organic light-emitting material above the first electrodes;
• forming a second electrode above the light-emitting layers;
• forming a first protection layer through applying resin material above the second electrode excluding an auxiliary region which, in plan view, extends in a column direction between ones of the first electrodes that are adjacent in a row direction across the substrate;
• forming a second protection layer through applying inorganic material above the first protection layer and the second electrode;
• forming a contact opening in the second protection layer within the auxiliary region;
• and
• forming an auxiliary electrode layer within the auxiliary region in the column direction, the auxiliary electrode layer electrically connecting to the second electrode through the contact opening.

An organic electroluminescence (EL) display panel, comprising:

• a substrate;
• a plurality of first electrodes arrayed in rows and columns above the substrate, wherein adjacent first electrodes of the plurality of first electrodes are spaced from each other;
• a plurality of light-emitting layers, wherein each of the plurality of light-emitting layers is over a corresponding first electrode of the plurality of first electrodes, and each of the plurality of light-emitting layers comprises an organic material;
• a second electrode over the plurality of light-emitting layers;
• a first protection layer over the second electrode, wherein the first protection layer fails to extend into an auxiliary region which, in plan view, extends in a column direction between the adjacent first electrodes, and the first protection layer comprises a resin;
• a second protection layer over the first protection layer and the second electrode, wherein the second protection layer comprises an inorganic material;
• an auxiliary electrode layer that extends in the column direction within the auxiliary region and is electrically connected to the second electrode within the auxiliary region;
• a plurality of first partition walls between the auxiliary region and a light emitting region, wherein each of the plurality of first partition walls has a first height;
• a second partition wall between adjacent first partition walls of the plurality of first partition walls, wherein the second partition wall has a second height different from the first height.
