Abstract
Provided are a display including a nano-scale LED and a method for manufacturing the same. In detail, nano-scale LED devices, each of which has a nano unit, are connected to nano-scale electrodes without electrical short-circuit to overcome a limitation in which it is difficult to allow nano-scale LED devices according to the related art to stand up and be coupled to electrodes and a limitation in which it is difficult to allow the nano-scale LED devices to be one-to-one coupled to the nano-scale electrodes different from each other, thereby realizing a display including the nano-scale LEDs. Also, the display may have superior light extraction efficiency and prevent defective pixels and the defect of the whole display due to the defects of the nano-scale LED devices, which may rarely occur, from occurring to minimize the defects of the display including the nano-scale LEDs and maintain its original function.
