Patent ID: 8358060

Claim:
An organic light emitting device, comprising: a first pixel to display a first color light, a second pixel to display a second color light, and a third pixel to display a third color light, wherein each of the first pixel, the second pixel, and the third pixel comprises a pixel electrode, a third color organic emission layer disposed on the pixel electrode, a common electrode disposed on the third color organic emission layer, and a hole injection layer and a hole transport layer disposed on the whole surface of the pixel electrode of the first pixel, the second pixel and the third pixel, wherein the first pixel further comprises a first color organic emission layer disposed between the pixel electrode and the common electrode, wherein the second pixel further comprises a second color organic emission layer and a first distance additional member between the pixel electrode and the common electrode, wherein the third pixel further comprises a second distance additional member disposed between the pixel electrode and the common electrode, wherein the first distance additional member is thicker than the second distance additional member, and wherein the first additional member and the second additional member are made of the same material of the hole transport layer, wherein the distances between the pixel electrode and the common electrode of the first pixel, the second pixel, and the third pixel are referred to as a first resonance distance, a second resonance distance, and a third resonance distance, respectively, and a resonance order of the first color light for the first resonance distance is lower than at least one of resonance orders of the second color light and the third color light for the second resonance distance and the third resonance distance, respectively.
