a micro deflector covering the emission area and at least a part of the non-emission area of a corresponding pixel area, the micro deflector configured to deflect light scattered into the non-emission area from the emission area to a normal direction with respect to a surface of the substrate, and to provide the deflected lights to the imaging lens,

wherein the imaging lens is spaced apart from the display panel by a focal length of the imaging lens.

2. The display according to the claim 1 , wherein the emission area is provided to the imaging lens as a magnified image by the micro deflector, and
wherein the non-emission area is provided to the imaging lens as a scaled-down image by the micro deflector.

3. The display according to the claim 1 ,
wherein the micro deflector includes:
a minimum rim that is spaced apart from an edge line of the emission area in a direction toward the emission area by a first distance; and
a maximum rim that is apart from the edge line of the emission area in a direction toward the non-emission area by a second distance.

4. The display according to the claim 3 , wherein the maximum rim of the micro deflector is positioned inside of a middle line that is between the edge line of the emission area and a neighboring edge line of a neighboring emission area, the maximum rim being spaced apart from the middle line by a predetermined distance.

5. The display according to the claim 3 , wherein the micro deflector includes a transparent material having a profile in which a thickness of the micro deflector gradually decreases from the minimum rim to the maximum rim.

6. The display according to the claim 3 , wherein the micro deflector includes a convex lens disposed at an inner area surrounded by the maximum rim.

7. The display according to the claim 3 , wherein the micro deflector includes an outer convex lens disposed between the minimum rim and the maximum rim.

8. The display according to the claim 7 , wherein the micro deflector further includes an inner convex lens disposed at an inner area surrounded by the minimum rim.

9. The display according to the claim 7 , wherein the micro deflector further includes a planar portion disposed at an inner area surrounded by the minimum rim.
