Among the above display devices, the reflective type has a drawback that the visibility is inferior to that of the self-luminous type. The built-in ones are not maintenance-friendly and economical because regular battery replacement is necessary to prevent operation stoppage due to running out of batteries, and those using commercial power supply require extensive power line construction depending on the installation location Therefore, there is a disadvantage that the cost is increased and the operation cannot be performed in an emergency such as a power failure. further,
Self-luminous continuous lighting for all nights consumes a large amount of power, and especially when a battery is used, is extremely uneconomical because the battery is drastically consumed.

The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a self-contained information transmitting apparatus which has good visibility, is economical, and is easy to maintain.
