A display panel for use on a golf cart is composed of layered transparent panels and frame members adhered together. Two transparent panels are separated by a set of spacer members to form a cavity between the transparent panels. The cavity is accessible via an opening at one end of the display panel and is sealed with a removable spacer member inserted between the transparent panels. Two frame members are adhered respectively to each of the two transparent panels. The display panel is mounted to the canopy supports of a golf cart with clamps attached to each end of the display panel.
