A display device, comprising:

• a backlight, configured to provide an illumination light;
• a display panel, disposed on a transmission path of the illumination light to convert the illumination light into a display light;
• a viewing angle control panel, configured to control a light emission angle of the display device;
• a first polarizing unit, disposed between the backlight and the display panel and having a first absorption axis;
• a second polarizing unit, disposed between the display panel and the viewing angle control panel and having a second absorption axis;
• and
• a third polarizing unit, disposed on the viewing angle control panel and having a third absorption axis,
• wherein the third absorption axis is perpendicular to the first absorption axis and the second absorption axis, and the first absorption axis and the second absorption axis are perpendicular to each other on a same plane;
• wherein the first absorption axis and the second absorption axis are not parallel to each other, the first absorption axis and the third absorption axis are not parallel to each other, and the second absorption axis and the third absorption axis are not parallel to each other.
