Abstract:
1. A fabricating method of an electro luminescence display device, comprising: attaching to a roller a resin plate with a plurality of display concavo-convex patterns formed at a location corresponding to a display area of a substrate and with at least one dummy concavo-convex pattern formed at a location corresponding to a non display area of the substrate; supplying an organic material to the resin plate; and printing the organic material spread on the resin plate to the substrate by rotating the roller, wherein each of convex surfaces of the display concavo-convex patterns and the dummy concavo-convex pattern has a hemispherical shape with a same size, wherein the resin plate has a first base surface formed between outmost one of the display concavo-convex patterns and the dummy concavo-convex pattern and a second base surface formed on outer side of the dummy concavo-convex pattern, wherein a height from the first base surface to the convex surface of the display concavo-convex patterns is smaller than a height from the second base surface to the convex surface of the dummy concavo-convex pattern, and wherein a height of the first base surface is different from that of the second base surface.
