  • Patent number: 8389980
    Abstract: Provided is a light emitting apparatus in which light extraction efficiency can be improved without adversely affecting a functional layer of a light emitting device. The light emitting apparatus includes multiple light emitting devices formed on a substrate, each of the multiple light emitting devices at least including: a reflective layer; a first electrode; the functional layer including an emission layer with an emission region; and a second electrode. In which an optical waveguide including a periodic structure is formed between the emission regions and the optical waveguide includes a surface which is opposite to the substrate and is more repellent to a light emitting material liquid for forming the emission layer than the emission region.

  • Patent number: 7955786
    Abstract: Provided is a light transmissive stamper having light transmissivity with respect to an ultraviolet ray and durability for repeated use. Specifically, on a light transmissive substrate, a light transmissive auxiliary layer and an inorganic resist layer are formed sequentially, and a light beam is selectively irradiated to the inorganic resist layer, to thereby modify an inorganic resist ranging from a surface of the inorganic resist layer to a surface of the light transmissive auxiliary layer. Then, a part modified by the light beam or an unmodified part is selectively removed until the light transmissive auxiliary layer is exposed, thereby forming an uneven pattern corresponding to an information pattern in the inorganic resist layer.

  • Publication number: 20090246712
    Abstract: Provided is a stamper for producing a multilayer optical recording medium, which can be produced in simple steps and can be repeatedly used. Particularly, provided is a stamper for producing a multilayer optical recording medium, including: a translucent substrate; and a translucent inorganic resist layer in which a pit or a guide groove is formed on the substrate. Further, the stamper has an absorptivity of 10% or more with respect to exposure light which is used in patterning the inorganic resist layer, and has a transmittance of 19% or more with respect to an ultraviolet ray which is used when the stamper is used. Furthermore, the inorganic resist layer contains a tungsten oxide or a molybdenum oxide having a composition in which oxygen is lost from a stoichiometric composition.
