The invention relates to an organic white light-emitting diode comprising at least one blue light-emitting fluoranthene derivative of the general formula I as component A and at least one blue light-emitting arylamine derivative as component B, the HOMO energies and LUMO energies of components A and B being different, with the condition that the LUMO energy of component A is higher than the HOMO energy of component B; to a composition comprising at least one blue light-emitting fluoranthene derivative of the formula I as component A and at least one blue light-emitting arylamine derivative as component B, the HOMO energies and LUMO energies of components A and B being different, with the condition that the LUMO energy of component A is higher than the HOMO energy of component B; and also to a light-emitting layer comprising a composition and to an organic white light-emitting diode comprising an inventive composition or an inventive light-emitting layer. The invention further relates to a device selected from the group consisting of stationary visual display units such as visual display units of computers, televisions, visual display units in printers, kitchen appliances and advertising panels, illuminations, information panels and mobile visual display units such as visual display units in mobile telephones, laptops, vehicles and destination displays in buses and trains, comprising at least one inventive organic light-emitting diode, and to the use of an inventive composition in an organic white light-emitting diode.
