Claim 25:
26. A display apparatus comprising:
a display module defining a display surface comprising a right-eye display area and a left-eye display area, wherein the display module emits light; and
an optical system comprising a lens disposed in a path of the light emitted from the display module to enlarge an image display by the light,
wherein the display module comprises:
a display panel comprising a plurality of pixels which displays an image on the right-eye display area and the left-eye display area;
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 a portion of 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.
