  • Patent number: 7718452
    Abstract: Disclosed is a display apparatus, and method of making same, including a plurality of lower electrodes patterned on a substrate on the basis of each pixel, an auxiliary wiring composed of the same layer as the lower electrodes and arranged in the state of being insulated from the lower electrodes, an insulating film formed on the substrate and provided with pixel openings for exposing central portions of the lower electrodes and connection holes reaching the auxiliary wiring, organic layers so patterned as to cover bottom portions of the pixel openings and to have end portions partly overlapping on each other between the adjacent pixels, and an upper electrode so formed as to cover the organic layers and to be connected to the auxiliary wiring through the connection holes between the organic layers.

  • Patent number: 6884556
    Abstract: Electrophotographic photoreceptors having improved mechanical properties, electrical properties with excellent response characteristics are prepared by forming a photosensitive layer on an electroconductive substrate. The photosensitive layer contains a binder resin, which may be a polyarylate or a copolymer of polyarylate. The binder resin may be mixed with other resins up to 50 wt % with other resins to impove surface slip properties or fire retardant properties.
