Display device

A display device, comprising:

• a display panel, including a plurality of pixels emitting light from a light-exiting side;
• and
• a birefringent structure disposed at the light-exiting side of the display panel,
• wherein:
• a plane of the birefringent structure is parallel to a plane of the display panel;
• an optical axis of the birefringent structure forms an acute angle with respect to a first direction, the first direction being a direction perpendicular to the plane of the birefringent structure toward a light-exiting direction;
• a direction of the optical axis of the birefringent structure directly controls the light emitted from each of the plurality of pixels to be deflected by a deflection distance;
• and
• when the display device is in a display stage, the birefringent structure and the display panel are configured with a relative rotation at a plane parallel to the plane of the birefringent structure to enlarge each of the plurality of pixels by the deflection distance at all sides without moving a center point of the corresponding pixel to cover at least a portion of gaps between the plurality of pixels.
