Organic light-emitting device and method for producing the same

A method for producing an organic light-emitting device comprising a plurality of organic light-emitting elements including a first organic light-emitting element which emits a light of a first emission color and a second organic light-emitting element which emits a light of a second emission color different from the first emission color, comprising the steps of:

• forming a first electrode having a light reflection layer and a transparent conductive layer on a substrate;
• forming an organic compound layer including a light-emitting layer on the first electrode;
• and
• forming a second electrode as a light extraction electrode on the organic compound layer,
• wherein the step of forming the first electrode comprises, in mentioned order:
• a step of forming the light reflection layer on a region of the first organic light-emitting element,
• a step of forming the transparent conductive layer on and between both regions of the first and second organic light-emitting elements,
• a step of forming the light reflection layer on the region of the second organic light-emitting element, and
• a step of removing the transparent conductive layer formed between the elements.
