A circular display includes a columnar waveguide plate and an image projection device. The upper width of the cross-section of the columnar waveguide plate is less than the bottom width of the cross-section of the columnar waveguide plate. The outer surface of the columnar waveguide plate is utilized for displaying an image, and the image projection device is used for projecting the image to the bottom of the columnar waveguide plate.
