A display device includes: a first substrate; a second substrate on the first substrate and facing the first substrate, the second substrate having a first electrode on a surface thereof; a third substrate on the second substrate and facing the second substrate, the third substrate having a second electrode on a surface thereof, the second electrode facing the first electrode and configured to form an electric field between the first electrode and the second electrode; a barrier layer interposed between the second substrate and the third substrate, the barrier layer configured to selectively control transmission and blockage of light in regions thereof corresponding to each of a plurality of pixels; and a first polarizing plate on the third substrate and configured to transmit a portion of light passing through the barrier layer, the portion of light having a first phase, the barrier layer including electrochromic elements.
