  • Patent number: 8198806
    Abstract: Reducing the manufacturing cost of an EL display device and an electronic device furnished with the EL display device is taken as an objective. A textured structure in which projecting portions are formed on the surface of a cathode is used. External stray light is diffusely (irregularly) reflected by the action of the projecting portions when reflected by the surface of the cathode, and therefore a defect in which the face of an observer or the surrounding scenery is reflected in the surface of the cathode can be prevented. This can be completed without using a conventionally necessary high price circular polarizing film, and therefore it is possible to reduce the cost of manufacturing the EL display device.

  • Patent number: 8049418
    Abstract: The luminance of different colors of light emitted from EL elements in a pixel portion of a light emitting device is equalized and the luminance of light emitted from the EL elements is raised. The pixel portion of the light emitting device has EL elements whose EL layers contain triplet compounds and EL elements whose EL layers contain singlet compounds in combination. The luminance of light emitted from the plural EL elements is thus equalized. Furthermore, a hole transporting layer has a laminate structure to thereby cause the EL elements to emit light of higher luminance.
