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 fabrication apparatus and method use a mold for forming a pattern. The fabrication may be related to a thin film transistor (TFT) used for a switching element and a driving element in a display device, such as a liquid crystal display (LCD) or organic electroluminescent display (OELD). The fabrication method and apparatus fabricate a soft mold using a resin layer that is attached to a back plane in substantially a vacuum environment. The resin layer may be irradiated with ultraviolet (UV) light and then detached from a master plate to form a desired pattern. The fabrication process is such that the soft mold is relatively thin and light-weight, but resistant to being damaged.
