  • Patent number: 7195826
    Abstract: The new organic electroluminescent display device has a carrier-transporting layer and/or an organic luminous layer composed of a nematic liquid crystal or a liquid crystal dispersing a carrier-transporting low-molecule therein. When the organic luminous layer is to be bestowed with faculty as a liquid crystal, it is made of a nematic liquid crystal. Both the carrier-transporting layer and the organic luminous layer may be bestowed with faculty as a liquid crystal. Since the liquid crystal is incorporated in the carrier-transporting layer and/or the organic luminous layer, the display device can be driven as a liquid crystal display device in a dark place by charging with a voltage lower than a light emission initiating potential. Of course, it is driven as an electroluminescent display device when it is charged with a voltage higher than the light emission initiating potential. Use of an electroluminescent liquid crystal as a organic luminous layer enables omission of a carrier-transporting layer.

  • Patent number: 6794278
    Abstract: Disclosed is a method for forming a thin-film layer, such as a metallic film or a transparent conductive film, on a functional organic layer formed from an organic compound, by means of a sputtering method performed at a low discharge voltage and a low gas pressure, without imparting any damage to the surface of the organic layer. The thin-film layer is formed by use of a facing-targets-type sputtering apparatus including a pair of facing targets disposed a predetermined distance away from each other; an electron reflection electrode disposed on the periphery of each target; and magnetic field generation means disposed at the sides of each target. The magnetic field generation means generates a magnetic field extending from one target to the other so as to surround a confinement space provided between the paired targets, as well as a magnetic field having a portion parallel to the surface of each target in the vicinity of a peripheral edge portion of the target.
