Abstract: A light emitting display device includes a substrate that includes a first pixel, a second pixel, a third pixel, and an infrared ray emission portion, the first pixel, the second pixel, and the third pixel representing different colors, a first electrode on the substrate, a second electrode that overlaps 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 emission layer may include a first emission layer in the first pixel and an infrared ray emission layer in the infrared ray emission portion, the auxiliary layer may include a first auxiliary layer in the first pixel, and the infrared ray emission layer and the first auxiliary layer may include the same material.
