a lens comprising a first surface and a plurality of side surfaces;
a display device on a first side surface from among the plurality of side surfaces, the display device being configured to provide light to the first side surface;
a first reflector in the lens and configured to reflect the light provided by the display device after the light is reflected from a second side surface from among the plurality of side surfaces to the first surface; and
an optical path changing member between the first side surface and the display device, the optical path changing member being configured to change a path of the light provided by the display device such that the light provided by the display device travels toward a third side surface of the lens,
wherein the light provided by the display device is reflected by the third side surface from among the plurality of side surfaces to travel toward a fourth side surface from among the plurality of side surfaces, and is reflected by the fourth side surface to travel toward the second side surface,
wherein the third side surface extends from a first side of the first side surface, and
wherein the fourth side surface is between the second side surface and the third side surface.
