Abstract: A display device may include: a light-emitting-element layer disposed on a substrate, and including an anode electrode, a cathode electrode, a first sub-pixel including a first emission structure, a second sub-pixel including a second emission structure, and a third sub-pixel including a third emission structure; and a lens-array layer on the light-emitting-element layer, and including lenses including first, second, and third lenses provided to respectively overlap the first, second, and third emission structures. In the first sub-pixel, first base light provided from the first emission structure may pass through the first lens and be provided as first light. In the second sub-pixel, second base light provided from the second emission structure may pass through the second lens and be provided as second light. In the third sub-pixel, third base light provided from the third emission structure may pass through the third lens and be provided as third light.
