    摘要: The present invention provides a light-emitting device includes first, second and third light-emitting elements, emitting light having different color. The first light-emitting element includes a first anode; a first cathode; and first and second light-emitting layers therebetween, wherein the first light-emitting layer includes a first high light-emitting substance and a first organic compound, and the second light-emitting layer includes the first high light-emitting substance and a second organic compound. The second light-emitting element includes a second anode; a second cathode; and a third light-emitting layer and a layer for controlling carrier transfer therebetween, wherein the third light-emitting layer includes a second high light-emitting substance, wherein the layer for controlling carrier transfer includes third and fourth organic compounds. The third light-emitting element includes a third anode; a third cathode; and a fourth light-emitting layer, wherein the fourth light-emitting layer includes fifth and sixth organic compounds, and a third high light-emitting substance.
