ORGANIC LIGHT EMITTING DEVICE, METHOD OF MANUFACTURING THE SAME, AND ORGANIC LIGHT EMITTING DISPLAY APPARATUS USING THE SAME

摘要

Disclosed are an organic light emitting device, a method of manufacturing the same, and an organic light emitting display apparatus using the same. In the organic light emitting device, an electron transporting layer is not provided between an emission layer and an electron injecting layer. Instead, the emission layer includes a first emission layer on a hole transporting layer, and a second emission layer on the first emission layer. The second emission layer includes a same material as a material of the first emission layer and further includes an n-type dopant material.

主权项

1. An organic light emitting device, comprising:
an anode; a hole injecting layer on the anode; a hole transporting layer on the hole injecting layer; an emission layer on the hole transporting layer, wherein the emission layer includes a host material and a dopant material; an electron injecting layer on the emission layer; and a cathode on the electron injecting layer, wherein the emission layer comprises a first emission layer on the hole transporting layer, and a second emission layer on the first emission layer, and wherein the second emission layer comprises a same material as a material of the first emission layer and further comprises an n-type dopant material.
