Abstract

PURPOSE: To obtain a display of variable information usable as a display for interior use by forming the display which is made visible from the entire circumference, is inexpensive and is capable of dealing with a trend toward a higher density and coloration by plural light emitting element arrays arranged on a rotary cylinder. CONSTITUTION: The light emitting element arrays 3 are arranged parallel with the axis of rotation of the cylinder 2 connected to a driving means and evenly on the circumference around this cylinder. A synchronous light emission control means 4 is installed in the inside part of the cylinder and a cover 5 is formed transparent in the necessary parts to make the light emission visible from outside. As a result, the information of the luminance visible from the entire circumference and sufficiently usable in the daytime as well is made displayable. The expression of the display having the increased information quantity with the device of the same size is made possible and the sufficient dealing with coloration is possible as well. Such display is formable with the extremely small number of elements.
