  • Patent number: 7221094
    Abstract: An electroluminescent display (EL) device and a method of manufacturing the same. The EL device includes a substrate, a first electrode unit including first electrodes formed on the substrate in a predetermined pattern, and first electrode terminals connected to the respective first electrodes; a second electrode unit including second electrodes formed on the first electrodes, and second electrode terminals connected to the respective second electrodes; an emission area formed where the first electrodes intersect the second electrodes, an electroluminescent layer disposed between the first electrodes and the second electrodes in the emission area, and an outer insulating layer between the emission area and the second electrode terminals; wherein the outer insulating layer comprises an insulating material formed to contact at least an edge of the second electrode terminals facing the emission area to reduce a steepness of a step between the second electrode terminal and the substrate.

  • Publication number: 20060168839
    Abstract: A layer on a semiconductor substrate is scanned with a stream of heated gas to bake the layer. A baking apparatus includes a stage that supports the semiconductor substrate and a gas injector that expels the stream of the heated gas. The stage and the gas injector are moved relative to one another to scan the substrate with the stream of heated gas and thus, bake the layer that is disposed thereon. Fumes emanating from the layer are removed while the layer is scanned. To this end, the apparatus also includes a vacuum head that is fixed in position relative to the gas injector.

  • Patent number: 6794815
    Abstract: An organic electroluminescent display (EL) device includes a substrate, an organic light emitting portion formed such that a positive electrode formed in a predetermined pattern, an organic layer formed on the positive electrode, and a negative electrode having a predetermined pattern in a direction orthogonal with the positive electrode are sequentially stacked, an encapsulation cap which encapsulates the organic light emitting portion, first and second groups of electrodes which are drawn out from at least one edge of the encapsulation cap and connected to the positive and negative electrodes to drive the organic light emitting portion, and first and second dummy electrodes formed at one side of the substrate.
