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 sub LED electrically coupled 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.

Abstract: An LED display apparatus with a simplified manufacturing process is provided. The LED display apparatus includes a common electrode layer on a first substrate, a second substrate including a first pixel driving device and a second pixel driving device, and a first light emitting device and a second light emitting device on the common electrode layer. The first light emitting device includes a first n-type semiconductor layer, a first active layer, and a first p-type semiconductor layer. The second light emitting device includes a second n-type semiconductor layer, a second active layer, and a second p-type semiconductor layer. As such, it is possible to provide an LED display apparatus with improved manufacturing reliability having at least one unit pixel composed of pixels by using at least one light emitting device integrated with the common electrode layer and at least two individual light emitting devices.
