An illuminated display for displaying logos, messages, pricing information and the like, utilizes the large glass surfaces of modern office buildings, banks, hotels and shade material adapted to be backlit from the building interior. The shade material may contain translucent and opaque portions configured to provide, when combined with adjacent shade portions, a representation of the information to be conveyed to an observer of the structure. In the most preferred embodiment the shades are coupled to a timer mechanism so they may be operated simultaneously, e.g. to close them at sunset or to open them at sunrise. Various degrees of transparency may be provided, as may color, to give the designer a large selection of options for carrying out the informational and artistic aspects of the invention.
