Abstract: A display device includes a display panel, a first polarizer, a liquid crystal lens, a first quarter-wave plate, and a second quarter-wave plate. The display panel displays an image. The first polarizer disposed on the display panel reflects a first light having a polarization direction parallel to a reflection axis of the first polarizer. The liquid crystal lens includes liquid crystal molecules and changes a phase of the first light or a second light according to a driving signal applied to the liquid crystal lens. The second and first lights travel in opposite directions with respect to each other. The first quarter-wave plate is disposed between the first polarizer and the liquid crystal lens. The second quarter-wave plate is disposed between the liquid crystal lens and a second polarizer. The display device operates in a mirror mode, a three-dimensional mode, and a two-dimensional mode according to the driving signal.
