    • In a laser irradiation device, a patterning method and a method of fabricating an Organic Light Emitting Display (OLED) using the same. The laser irradiation device includes a light source, a mask, a projection lens, and a Fresnel lens formed at a predetermined portion of the mask to change an optical path. When an organic layer pattern is formed using the laser irradiation device, laser radiation is irradiated onto a region of an organic layer, which is to be cut, and the laser radiation is appropriately irradiated onto a region of the organic layer, which is to be separated from a donor substrate. The laser radiation irradiated onto an edge of the organic layer pattern has a laser energy density greater than that of the laser radiation irradiated onto other portions of the organic layer pattern. As a result, it is possible to form a uniform organic layer pattern and reduce damage of the organic layer.
    • 在激光照射装置,图案化方法和使用其的有机发光显示器(OLED)的制造方法中, 激光照射装置包括形成在掩模的预定部分处的光源,掩模,投影透镜和菲涅耳透镜,以改变光路。 当使用激光照射装置形成有机层图案时,将激光照射到要切割的有机层的区域上,并将激光辐射适当地照射到有机层的区域 与供体底物分离。 照射到有机层图案的边缘上的激光辐射的激光能量密度大于照射到有机层图案的其它部分上的激光辐射的激光能量密度。 结果,可以形成均匀的有机层图案并减少有机层的损伤。
