1. A display device comprising:
a substrate;
a plurality of display elements disposed on the substrate;
a pixel definition film including a plurality of openings which overlap the plurality of display elements;
an encapsulation layer disposed on the plurality of display elements and the pixel definition film; and
a diffraction pattern layer comprising a plurality of diffraction patterns disposed on the encapsulation layer with a predetermined pitch,
wherein the plurality of diffraction patterns diffracts light emitted from the plurality of display elements in a pattern different from an arrangement pattern of the plurality of display elements,
wherein a number of light emission patterns of the light diffracted by the plurality of diffraction patterns is greater than a number of light emission patterns of the light emitted from the plurality of display elements, and
wherein the plurality of diffraction patterns does not overlap at least one opening of the plurality of openings.
