    • Disclosed is a light-emitting device having high luminous efficiency and excellent durability. Specifically disclosed is a light-emitting device which comprises at least a light-emitting layer arranged between an anode and a cathode and emits light by an electrical energy. This light-emitting device is characterized in that the light-emitting layer contains a pyrene compound represented by the general formula (1) below and an organic fluorescent substance having a fluorescence peak wavelength of not less than 500 nm but not more than 680 nm (In the formula, R1-R15 may bethe same or different and each represents a member selected from the group consisting of a hydrogen, alkyl groups, cycloalkyl groups, heterocyclic groups, alkenyl groups, cycloalkenyl groups, alkynyl groups, alkoxy groups, alkylthio groups, arylether groups, arylthioether groups, aryl groups, heteroaryl groups, an amino group, a silyl group,-P(=O)R16R17 groups and ring structures formed together with an adjacent substituent, and R16 and R17 are be selected from aryl groups and heteroaryl groups; n-number of R1-R10 is used for a linkage with a bicyclic benzoheterocyclic ring, and n is an integer of 1-4; X is selectedfrom an oxygen atom, a sulfur atom and a-NR18-group, and R18 is selected from a hydrogen, alkyl groups, cycloalkyl groups, heterocyclic groups, aryl groups and heteroaryl groups; and R18 and R15 may combine together to form a ring).
