Display device

A display device, comprising:

• a beam splitting element, configured to receive an illumination beam and allow an image beam to pass through, wherein the illumination beam is reflected in the beam splitting element and transmitted in a first direction;
• a polarization modulating element, disposed on one side of the beam splitting element along the first direction, and configured to modulate or maintain polarization states of the illumination beam and polarization states of the image beam;
• a light shifting element, disposed on one side of the polarization modulating element along the first direction, and configured to modulate the image beam having the polarization state to be shifted by a distance, wherein the polarization modulating element is disposed between the beam splitting element and the light shifting element;
• and
• a reflective liquid crystal panel, disposed on one side of the light shifting element along the first direction, and configured to receive the illumination beam and emit the image beam in a second direction, wherein the first direction is opposite to the second direction, wherein the light shifting element is disposed between the polarization modulating element and the reflective liquid crystal panel.
