Summary:PROBLEM TO BE SOLVED: To provide an organic light-emitting device with a luminous efficacy (current luminous efficacy) per unit current. SOLUTION: The organic light-emitting device has a luminous layer containing a conjugated polymer between an electron transport layer containing the conjugated polymer and a hole transport layer containing the conjugated polymer. In the organic light-emitting device, electron mobility in the luminous layer is 1/2 times or less the electron mobility in the electron transport layer, and hole mobility in the luminous layer is 1/2 times or less the hole mobility in the hole transport layer.
