  • Patent number: 8674370
    Abstract: Panel (11) of the present invention includes substrate (12) having flat surface (12a?) having rectangular display section (13), and adjacent surface (12b?) curved from an edge part of surface (12a?) in the vicinity of a long side of surface (12a?). On surface (12b?), terminals, extending from display section (13) (in the vicinity of the long side), are arranged. Edge parts of surfaces (12a?) of substrates (12) of adjacent panels (11) are combined so that longitudinal directions of light-emitting sections (13) are parallel to each other. Surface (12b?) projects on a back surface side of substrate (12). It is thus possible to provide a light-emitting panel device realizing a large light-emitting surface by combining a desired number of panels, an image display device including the light-emitting panel device, an illumination device including the light-emitting panel device, a panel in the light-emitting panel device, and a method of producing the panel.

  • Patent number: 8664669
    Abstract: An organic EL element has an anode, a cathode, a hole injection layer and at least one functional layer disposed between the anode and the cathode. The at least one functional layer contains an organic material. Holes are injected into the functional layer from the hole injection layer, which contains a tungsten oxide. A Ultraviolet Photoelectron Spectroscopy (UPS) spectrum obtained from a UPS measurement has a protrusion near a Fermi surface and within a region corresponding to a binding energy range lower than a top of the valence band. The tungsten oxide contained in the hole injection layer satisfies a condition, determined from an X-ray Photoelectronic Spectroscopy measurement, that a ratio in a number density of atoms other than tungsten and oxygen atoms to the tungsten atoms does not exceed approximately 0.83.
