Organic light-emitting elements of LED with light reflection layers in each spaced on opposite sides of transparent conductive layer

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 first 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 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 commonly forming the first transparent conductive layer on 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.

An organic light-emitting device, comprising:

• a substrate;
• and
• a plurality of organic light-emitting elements formed on the substrate,
• wherein the plurality of the organic light-emitting elements include 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,
• wherein each of the organic light-emitting elements has a first electrode, an organic compound layer containing a light-emitting layer, and a second electrode in this order on the substrate,
• wherein the first electrode of the first and second organic light-emitting elements has a light reflection layer and a first transparent conductive layer,
• wherein the light reflection layer of the first organic light-emitting element is formed between the substrate and the first transparent conductive layer of the first organic light-emitting element, and
• wherein the light reflection layer of the second organic light-emitting element is formed between the first transparent conductive layer of the second organic light-emitting element and the organic compound layer of the second organic light-emitting element.
