摘要：
A display device includes an anode electrode, an organic light emitting layer, and a first cathode electrode. Provided are a plurality of light emitting elements in which the anode electrode, the organic light emitting layer, and the first cathode are separated for each sub-pixel, a protective layer covering the plurality of light emitting elements, and a second cathode electrode provided on the protective layer. The second cathode electrode is connected to each separated first cathode electrode.
