  • Patent number: 7348600
    Abstract: The invention provides a nitride semiconductor light-emitting device comprising gallium nitride semiconductor layers formed on a heterogeneous substrate, wherein light emissions having different light emission wavelengths or different colors are given out of the same active layer. Recesses 106 are formed by etching in the first electrically conductive (n) type semiconductor layer 102 formed on a substrate with a buffer layer interposed between them. Each recess is exposed in plane orientations different from that of the major C plane. For instance, the plane orientation of the A plane is exposed. An active layer is grown and joined on the plane of this plane orientation, on the bottom of the recess and the C-plane upper surface of a non-recess portion.

  • Patent number: 7320900
    Abstract: Before cutting a gang-printed substrate having a multiplicity of liquid crystal display panel regions provided thereon into individual liquid crystal display panels, a voltage is applied to all of the multiplicity of liquid crystal display panel regions to inspect display defects, polymerize a monomer in the liquid crystal component, and control alignment of the liquid crystal, which allows the time required for a voltage applying step to be reduced and allows a reduction in the manufacturing cost. A dispenser injection process is used to allow a liquid crystal to be injected between mother boards that have not been cut into individual display panels, and a voltage is applied after the pair of glass substrates are combined and before they are cut into individual display panels to perform a test on display defects (dynamic operating test), pretilt control, and an aligning process.
