    摘要: Aspects of the present invention provide a blue organic light-emitting device having a continuous operation lifetime. An organic light-emitting device includes a light-emitting layer containing a dopant having the ability to trap electrons or holes, and a hole-blocking layer or electron-blocking layer, in which the difference between the LUMO of the dopant and the LUMO of a host material, the size relationship between the HOMO of the host material and the HOMO of the dopant, and the difference between the T1 of the host material and the T1 of the hole-blocking layer or between the T1 of the host material and the T1 of the electron-blocking layer, are specified.
