Abstract
An organic light-emitting device includes a first electrode, a second electrode, and a light-emitting layer disposed between the first and second electrodes. The light-emitting layer contains an organic compound emitting photoluminescent light with a peak wavelength of 430 to 480 nm. The organic compound has a profile factor of 0.02 or less at a wave number of 1,300 to 1,680 cmas calculated from Huang-Rhys factors.
