  • Composite thin film holding substrate, transparent conductive film holding substrate, and panel light emitting body
    Patent number: 7582351
    Abstract: There is provided a composite thin film-holding substrate in which a composite thin film (4) comprising a filler (2) having a refractive index lower than that of a substrate (1) and a binder (3) having a refractive index higher than that of the filler (2) is formed on a surface of the substrate (1). Light is efficiently scattered when passing through the composite thin film (3) which comprises the filler (2) and the binder (3) having different refractive indexes from each other. In addition, the refractive index of a composite thin film (4) comprising a filler (2) having a low refractive index is low. As a result, the discharge efficiency of light which passes through the composite thin film (4) from the substrate (1) to the external is improved.

  • Apparatus for and method of vacuum vapor deposition and organic electroluminescent device
    Patent number: 6696096
    Abstract: A vacuum vapor deposition apparatus includes a vacuum chamber having a plurality of vapor sources and a heater for heating the vapor sources to achieve vacuum vapor deposition on a surface of at least one substrate within the vacuum chamber. At least one of the vapor sources utilizes an organic material. A hot wall, which encloses the vapor sources and a space in which the vapor sources and the substrate confront each other, is heated to a temperature at which the organic material is neither deposited nor decomposed. The organic material is vapor deposited on the surface of the substrate by heating the vapor sources while the vapor sources and the substrate are moved relative to each other.
