Abstract
A display device includes a substrate with a first subpixel and a second subpixel; a first electrode on the substrate, including a first sub electrode provided on the first subpixel and a second sub electrode on the second subpixel; an organic light emitting layer on the first electrode; a second electrode on the organic light emitting layer; a first bank between the first sub electrode and the second sub electrode to partition the first subpixel and the second subpixel from each other; and a light absorption portion inside each of the first sub electrode and the second sub electrode to absorb external light. The first sub electrode includes a reflective metal to cover the light absorption portion. The reflective metal and the second electrode emit light emitted from the organic light emitting layer to the substrate by reflecting the light emitted from the organic light emitting layer.
