Abstract: A light emitting display device according to an embodiment of the present disclosure includes a display panel including a unit pixel, a first LED disposed in the unit pixel, and a second LED disposed in the unit pixel and emitting light of the same color as the first LED. When the first LED and the second LED are able to emit light normally, the first LED and the second LED alternately emit light.
