    摘要: A top-emitting organic light-emitting device (OLED) including a reflective first electrode layer; a semitransparent second electrode layer facing the first electrode layer; and an organic layer between the first electrode layer and the second electrode layer, wherein the organic layer comprises a first layer, a second layer, and an emission layer between the first layer and the second layer, wherein the sum of the thicknesses of the emission layer and the second layer is about 0.15 to about 0.30 times the thickness of the entire organic layer. The top-emitting OLED may have high efficiency, and thus driving voltage may be reduced.

    摘要: An organic electroluminescent device includes an emission layer interposed between a first electrode and a second electrode. The emission layer may be composed of a host material and a phosphorescent dopant material. The host material may be composed of a mixture of a hole transport material and an electron transport material. The hole transport material may be a carbazole compound and the electron transport material may include at least a compound selected from spirofluorenes and organic metal complexes. The use of the mixture facilitates the re-combination of holes and electrons in neighboring organic layers, thus decreasing the driving voltage and increasing the luminous efficiency and lifetime of the organic electroluminescent device.
