An organic light-emitting device includes an anode, a cathode, and an organic compound layer including at least a light-emitting sublayer and being arranged between the anode and the cathode, the light-emitting sublayer containing a host serving as a main component, a first dopant, and a second dopant, in which for the host, the first dopant, and the second dopant, the following relationships (a) to (c) hold, whereby only the second dopant emits light:n (a) first maximum emission wavelength (H)<first maximum emission wavelength (D1)<first maximum emission wavelength (D2), (b) LUMO (D2)<LUMO (D1)<LUMO (H), and (c) HOMO (D2) is equal to or lower than HOMO (H)<HOMO (D1). |
