摘要： An OLED, a method for fabricating the same, and a display device are disclosed. The OLED comprises a first electrode, a first carrier transporting layer, an organic light emitting layer, a second carrier transporting layer, a second electrode, and a light extracting layer between the first electrode and the organic light emitting layer. The light extracting layer is made from a first carrier transporting material. The light extracting layer is formed between the first electrode and the organic light emitting layer at a light exit side of the OLED, and is formed from the first carrier transporting material. This increases the light extracting efficiency of the OLED. The light extracting layer further acts the first carrier transporting layer, thus simplifying the structure of OLED, making OLED easy to fabricate, and efficiently controlling cost.
