A display device includes: a first base substrate which comprises a plurality of pixels; a pixel electrode on the first base substrate in each of the pixels and comprises a reflective film; an organic layer on the pixel electrode; and a common electrode on the organic layer, wherein the pixel electrode has a reflectance of 80% or more for light in a first wavelength range of 420 nm to 470 nm.

Display device

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.
