Abstract
An electronic device according to various embodiments comprises: a display including a plurality of pixels; a first polarizing plate arranged on a first area of the display and capable of rotating, in a first rotational direction, a first light outputted through one or more first pixels included in the first area; a second polarizing plate arranged on a second area of the display and capable of rotating, in a second rotational direction, a second light outputted through one or more second pixels included in the second area; a first mirror arranged to have a first designated incline on the first area and capable of reflecting the first light rotating in the first rotational direction; a second mirror arranged to have a second designated incline on the second area and capable of reflecting at least a part of the second light rotating in the second rotational direction; and a flat lens capable of transmitting a first reflective light obtained by allowing the first light rotating in the first rotational direction to be reflected through the first mirror, and a second reflective light obtained by allowing the second light rotating in the second rotational direction to be reflected throu…
