Claim 24:
25. A display apparatus comprising:
a display module defining a display surface comprising a plurality of light-emitting areas and a plurality of replication areas in a surface thereof,
wherein the display module comprises:
a display panel which displays an image on each of the light-emitting areas;
a light concentration layer arranged between the display panel and the display surface, 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, wherein the plurality of light concentration lenses change a direction of light incident thereto into a direction closer to a direction towards the display surface;
a buffer layer disposed between the light concentration lenses and the display surface; and
a plurality of diffraction patterns are arranged between the buffer layer and the display surface at regular intervals on the buffer layer, wherein the plurality of diffraction patterns diffract light incident thereto to display an image on each of the plurality of replication areas,
wherein the plurality of replication areas are arranged around one of the plurality of light-emitting areas on the display surface, 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.
