PROBLEM TO BE SOLVED: To provide a light display which can display in an eye-catching manner with excellent visibility, and which is configured compactly as a whole, and can be easily disassembled and assembled. SOLUTION: A device (A) configured by stacking display units UR, UY and UW that can perform an optical display of a predetermined color using light emitting diodes L1-L8 as a light source, on a base substrate 10 includes a power source circuit part PWC shared by the display units, and a display signal output circuit part DSC for outputting a display signal corresponding to each display unit. Each display unit includes a light emitting diode substrate 1, a drive circuit substrate 2 of the light emitting diode, a light reflecting and casting body 3 facing the light emitting diode, and translucent cover 4R (4Y, 4G and 4W) covering these. The drive circuit substrate 2 of at least one of the display units is a substrate that lights the light emitting diode as in a revolving light. COPYRIGHT: (C)2010,JPO&INPIT
