Abstract

A display device is provided. The display device includes a changeable reflective structure having a first changeable electrode, a changeable reflecting layer and a second changeable electrode, which are sequentially stacked on an upper substrate opposite a lower substrate. In the display device, the reflectance of the changeable reflecting layer may be adjusted by controlling a voltage applied to the first changeable electrode and the second changeable electrode according to a state of a light-emitting structure which is disposed on an emitting area of the lower substrate. Thus, in the display device, a decrease of the color sense by the reflection of external light in a display state may be prevented, and the reflective area may have sufficient reflectance for serving as a mirror in a non-display state.
