Organic light emitting display including color-adjusting layer and manufacturing method thereof

An organic light emitting display comprising:

• a substrate;
• a first electrode and a second electrode disposed on the substrate and opposed to each other;
• an organic light emitting layer positioned between the first electrode and the second electrode and including at least one first organic light emitting layer emitting first color light, at least one second organic light emitting layer emitting second color light, and at least one third organic light emitting layer emitting third color light;
• wherein the third color light is blue light;
• the first organic light emitting layer and the second organic light emitting layer are positioned to contact each other;
• a color adjusting layer contacting at least one of the first to third organic light emitting layers;
• the color adjusting layer is positioned between the first organic light emitting layer and the second electrode;
• and
• an electron transporting layer disposed between the color adjusting layer and the second electrode,
• wherein the color adjusting layer contains a first material having a high electron transport capability and a second material having a high hole transport capability.

A manufacturing method of an organic light emitting display, comprising:

• forming a first electrode on a substrate;
• forming at least one organic light emitting layer on the first electrode;
• forming a color adjusting layer on the at least one organic light emitting layer;
• forming an electron-transporting layer directly on the color adjusting layer;
• and
• forming a second electrode on the electron-transporting layer;
• and
• wherein the color adjusting layer contains a first material having a high electron transport capability and a second material having a high hole transport capability;
• wherein the at least one organic light emitting layer includes first and second organic light emitting layers formed to contact each other, the first organic light emitting layer emitting first color light, and the second organic light emitting layer emitting second color light;
• and
• wherein the color adjusting layer is positioned on the first organic light emitting layer or the second organic light emitting layer.
