Abstract: A light emitting display device includes a substrate having a first pixel, a second pixel, a third pixel, and an infrared emission portion. The first, second, and third pixels emit light of different colors. The light emitting device also includes a first electrode on the substrate, a second electrode overlapping the first electrode, an emission layer between the first electrode and the second electrode, and an auxiliary layer between the first electrode and the emission layer. The auxiliary layer includes a first auxiliary layer on the first pixel and a second auxiliary layer in the infrared emission portion. The first auxiliary layer and second auxiliary layer include a same material.
