Abstract: The present disclosure relates to an LED display device, and more particularly, to an LED display device including a repair structure for a deteriorated pixel. In the present disclosure, a subLED electrically connected to first and second connecting electrodes for applying a voltage to a LED is disposed on a deteriorated LED. Thus, deterioration of a display quality due to a deteriorated pixel is prevented. Since it is not required to remove a deteriorated LED, a fabrication cost is reduced and a process efficiency is improved.
