Light is prevented by a light shielding structure from falling in around the luminous screen. The concave mirror and the luminous screen are arranged such that light from the luminous screen will be reflected by the concave mirror to form the real image of the picture on the luminous screen in front of the concave mirror. The display device can produce visual effects of much interest and is highly effective in many applications such as display and adverti- sement of products for sale.
