    摘要： A display device includes a substrate having a red pixel region, a blue pixel region, and a green pixel region. An anode is on the substrate, a light-emitting layer is on the anode, and a cathode is on the light-emitting layer, wherein the light-emitting layer includes a red light-emitting layer emitting red light on the red pixel region, a blue light-emitting layer emitting blue light on the blue pixel region, and a green light-emitting layer emitting green light on the red pixel region, the blue pixel region, and the green pixel region. Each of the red light, the blue light, and the green light is resonated between the anode and the cathode.

    摘要： A light-emitting element with high emission efficiency which includes fluorescent materials is provided. The light-emitting element includes a first light-emitting layer and a second light-emitting layer. The first light-emitting layer includes a first fluorescent material and a first host material, and the second light-emitting layer includes a second fluorescent material and a second host material. The second host material includes a first organic compound and a second organic compound. The first organic compound and the second organic compound form an exciplex. A singlet excited energy level of the first host material is higher than a singlet excited energy level of the first fluorescent material, and a triplet excited energy level of the first host material is lower than a triplet excited energy level of the first fluorescent material.

    摘要： An organic light emitting device includes four sub-organic light emitting devices. The first device includes a first anode, a first common light emitting portion, and a first sub-light emitting portion. The second device includes a second anode, a second common light emitting portion, a first auxiliary layer, and a second sub-light emitting portion. The third device includes a third anode and a third common light emitting portion. The fourth device includes a fourth anode, a fourth common light emitting portion, and a light emitting layer emitting a first light. The first and second sub-light emitting portions have an integral structure and emit second light. The first, second, third, and fourth common light emitting portions have an integral structure and emit third light having a wavelength longer than a wavelength of at least one of the first or second lights.
