Yoshinobu Kashibuchi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Organic electroluminescent element and display panel using said element
    Patent number: 8084935
    Abstract: There are provided an organic electroluminescent (EL) element, which can realize the provision of a large screen by the formation of a film through coating in a simple and highly efficient manner, and a display panel using the same. The organic EL element comprises: a pair of opposed electrodes, a cathode and an anode; and an organic compound layer having a single-layer or multi-layer structure held between the pair of opposed electrodes, at least one layer constituting the organic compound layer being a layer containing at least one polymer comprising at least one monomer unit of a specific compound.
    Type: Grant
    Filed: November 9, 2004
    Date of Patent: December 27, 2011
    Assignee: Dai Nippon Printing Co., Ltd.
    Inventors: Satoshi Suzuki, Masato Okada, Yoshinobu Kashibuchi, Tohru Kobayashi
  • Charge transport monomer, charge transport material, and process for producing the same
    Patent number: 7105258
    Abstract: There is provided a charge transport material which can easily be coated to form a film, is less likely to be crystallized during or after film formation, has excellent charge transport capability, and high applicability to electronic devices. A charge transport monomer comprising conventional CBP with a specific substituent introduced thereinto is polymerized to prepare a polymer which is brought to a charge transport material comprising this polymer.
