  • Publication number: 20070275624
    Abstract: Manufacturing an organic EL display by: forming n types of color filter layers on a transparent substrate; forming a dye layer containing (n?1) types of color conversion dyes by a dry process; forming an organic EL device on the dye layer; and exposing the dye layer to dye-decomposing light from the side of the transparent substrate to form an m-th type color conversion layer at a position corresponding to an m-th type color filter layer; where n represents an integer from 2 to 6; m represents an integer from 1 to (n?1); each of the color filter layers transmits light in a different wavelength region; m-th type color conversion dye is decomposed by light cut by the m-th type color filter layer; and the m-th type color conversion layer emits light transmitted by the m-th type color filter layer after wavelength distribution conversion.

  • Patent number: 6570323
    Abstract: The organic thin-film light-emitting device includes a substrate, a plurality of first electrodes arranged parallel on the substrate, an electroluminescent layer made of an organic material and formed on the first electrodes, a plurality of second electrodes formed on the electroluminescent layer, and an electrically insulating barrier wall. The barrier wall includes barrier wall lines disposed at gaps in an electrode pattern of the second electrodes, and barrier wall end lines connected to the barrier wall lines so that the barrier wall lines do not have ant free ends. Thus, peeling-off of the barrier wall lines as a shadow mask at their end is prevented.

  • Patent number: 6215077
    Abstract: A thin-film laminate type conductor is provided which includes a first conductor that is a metal thin film formed of Al or Al alloy, and a second conductor that is a transparent conductive thin film formed of a metal oxide. The first and second conductors are formed in respective patterns on a transparent substrate, such that at least a part of the second conductor is laminated on at least a part of the first conductor. The transparent conductive thin film is composed of an amorphous film. In another embodiment, the first conductor is composed of laminated metal thin films one of which is formed of Al or Al alloy, and the other of which is formed of a high-melting-point metal. The Al or Al-alloy film is sandwiched between the substrate and the high-melting-point metal film.

  • Patent number: 6133581
    Abstract: An organic light-emitting device is formed of a transparent substrate, anodes in a stripe pattern formed on the transparent substrate, an organic film layer formed on the anodes, and cathodes formed on the organic film layer. Each of the anode includes a first conductor formed of a transparent and electrically conductive film containing a metal oxide as a main component, and a second conductor extending along the first conductor. The second conductor is formed of metal with a resistivity of 1/10 or less than a resistivity of a constituent material of the first conductor. Thus, the organic light-emitting device emits light efficiently with a low power consumption.
