摘要 |
An organic light-emitting device (OLED) having high luminescent efficiency in which most electrons and holes are combined within a light-emitting layer of the OLED is disclosed. The OLED comprises a first electrode formed on a substrate, at least one organic layer including an organic light-emitting layer, a second electrode formed on the organic layer, a hole inducing layer including a material having an ionization potential higher than that of the organic light-emitting layer and formed between the first electrode and the organic light-emitting layer and/or an electron blocking layer including a material having an electron affinity higher than that of the organic light-emitting layer and formed between the second electrode and the organic light-emitting layer.
