  • Patent number: 8736163
    Abstract: An organic electro-luminescence display device and a method for fabricating the same are provided. A first substrate and a second substrate are sealed by a sealant. An organic electro-luminescent diode is formed on the first substrate. The sealant contains a frit glass and a light-heat converter. The frit glass can reduce the moisture and oxygen transmission rate by preventing the organic electro-luminescent diode from being thermally decomposed during a curing process. Since the two substrates are encapsulated by the frit glass, the lifetime and reliability of the organic electro-luminescence display device can be increased.

    Abstract: A light-emitting device having the quality of an image high in homogeneity is provided. A printed wiring board (second substrate) (107) is provided facing a substrate (first substrate) (101) that has a luminous element (102) formed thereon. A PWB side wiring (second group of wirings) (110) on the printed wiring board (107) is electrically connected to element side wirings (first group of wirings) (103, 104) by anisotropic conductive films (105a, 105b). At this point, because a low resistant copper foil is used to form the PWB side wiring (110), a voltage-drop of the element side wirings (103, 104) and a delay of a signal can be reduced. Accordingly, the homogeneity of the quality of an image is improved, and the operating speed of a driver circuit portion is enhanced.
