Organic electroluminescent element

A method of manufacturing an organic electroluminescent element, comprising:

• forming a transparent electrode;
• forming a first light-emitting unit above the transparent electrode, the first light-emitting unit including a blue fluorescent light-emitting layer containing a blue fluorescent light-emitting material;
• forming an intermediate layer above the first light-emitting unit;
• forming a second light-emitting unit above the intermediate layer, the second light-emitting unit including a red phosphorescent light-emitting layer containing a red phosphorescent light-emitting material and a green phosphorescent light-emitting layer containing a green phosphorescent light-emitting material;
• and
• forming a reflecting electrode above the second light-emitting unit,
• wherein:
• the first light-emitting unit and the second light-emitting unit are stacked such that the intermediate layer is interposed between the first light-emitting unit and the second light-emitting unit;
• and
• in the forming of the second light-emitting unit, a film thickness (tR) of the red phosphorescent light-emitting layer and a film thickness (tG) of the green phosphorescent light-emitting layer satisfy a relation of 7*tR<tG.
