摘要： An organic light-emitting diode (“OLED”) includes a bottom electrode, a top electrode disposed opposite to the bottom electrode, and an organic layer that is interposed between the bottom electrode and the top electrode and includes a hole-transporting host and an electron-transporting host forming an exciplex and a phosphorescent dopant having a triplet energy which is lower than the triplet energy of the hole-transporting host, the triplet energy of the electron-transporting host, and the triplet energy of the exciplex, and a lighting device and a display apparatus including the OLED. Instead of a phosphorescent dopant, the fluorescent dopant having a singlet energy which is lower than the singlet energy of the exciplex may be also used.

An organic compound with high emission efficiency is provided. An organic compound having an excellent hole-transport property is provided. An organic compound having high reliability is provided. An organic compound that has a naphtho[2,3-b;7,6-b′]bisbenzofuran skeleton or a naphtho[2,3-b;7,6-b′]bisbenzothiophene skeleton and has a molecular weight of less than or equal to 5000 is provided. The present inventors have found that the organic compound is a significantly effective skeleton as a luminophor of a light-emitting element. The organic compound has high emission efficiency and exhibits favorable blue light emission; thus, a light-emitting element using the organic compound can be a blue light-emitting element with high emission efficiency.
