  • ORGANIC EL COMPONENT
    Publication number: 20070159088
    Abstract: An organic EL element includes a positive electrode layer, a hole injection layer, a hole transport layer, a light emitting portion, an electron transport layer, an electron injection layer, and a negative electrode layer laminated on a substrate. The light emitting portion has three first light emitting layers, three hole transport layers, and a second light emitting layer. The three first light emitting layers and the three layer hole transport layers are alternately laminated. The organic EL element is capable of enhancing luminous efficiency and minimizing the attenuation of the luminous efficiency and luminance.

  • Method of manufacturing organic electroluminescence display device
    Patent number: 6991954
    Abstract: A metal layer A constituting the stripe-shaped cathode electrode is formed on the surface of the organic electroluminescence layer 13, a peeling film B is stuck to the surface of the metal layer A through such an adhesive C as to reduce adhesion to the metal layer by the irradiation of ultraviolet light, and a pattern according to the stripe-shaped cathode electrodes 14 is baked onto the peeling film B by the irradiation of ultraviolet light E by using a mask D and the peeling film B is then peeled from the organic electroluminescence layer 13.
