Abstract: A display device can include a substrate including a plurality of sub-pixels, an overcoating layer on the substrate and including a base portion and protrusion portions, a first electrode corresponding to each of the plurality of sub-pixels and covering the base portion and the protrusion portions, a bank on a portion of the first electrode, an organic layer on the first electrode and the bank, a second electrode on the organic layer, an encapsulation unit on the second electrode, and a color filter on the encapsulation unit. The color filter can overlap another portion of the first electrode that is exposed by the bank. Therefore, it is possible to improve a luminance viewing angle and lateral visibility by disposing the color filter to overlap the emission area alone.
