1. A display apparatus comprising:
a display module defining a display surface in a surface thereof,
wherein the display module comprises:
a display panel comprising a plurality of display devices which displays an image on the display surface;
a light concentration layer arranged on the display panel, the light concentration layer including a bottom layer and a plurality of light concentration lenses disposed on an upper surface of the bottom layer, each of the plurality of light concentration lenses is spaced apart from each other exposing the upper surface of the bottom layer;
a buffer layer disposed on the plurality of light concentration lenses; and
a plurality of diffraction patterns arranged at regular intervals on the buffer layer,
wherein the plurality of diffraction patterns diffract lights incident thereto, and
wherein the plurality of diffraction patterns comprises a plurality of first diffraction patterns and a plurality of second diffraction patterns,
wherein the plurality of first diffraction patterns spaced apart from each other defining a first plurality of holes therebetween overlap each of the plurality of light concentration lenses and the plurality of second diffraction patterns spaced apart from each other defining a second plurality of holes overlap the upper surface of the bottom layer defined between adjacent condensing lenses of the plurality of condensing lenses.
