1. An electronic device comprising:
a display comprising a plurality of pixels;
a first polarizer disposed on a first area of the display and configured to rotate a first light output through one or more first pixels pertaining to the first area in a first rotational direction;
a second polarizer disposed on a second area of the display and configured to rotate a second light output through one or more second pixels pertaining to the second area in a second rotational direction;
a first mirror disposed on the first area at a first inclination and configured to reflect the first light that rotates in the first rotational direction;
a second mirror disposed on the second area at a second inclination and configured to reflect at least a portion of the second light that rotates in the second rotational direction; and
a flat lens configured to transmit a first reflected light obtained by reflecting the first light that rotates in the first rotational direction, on the first mirror, and a second reflected light obtained by reflecting the second light that rotates in the second rotational direction, on the second mirror,
wherein the flat lens forms a first focus corresponding to the first reflected light at a location before the first reflected light passes through the flat lens, and forms a second focus corresponding to the second reflected light at a location after the second reflected light passes through the flat lens.
