[Prior art]

 2. Description of the Related Art In recent years, planar light emitting devices using electroluminescence elements have come to be used in various displays. This electroluminescent device has a sheet-like transparent electrode on the front side and a sheet-like back electrode, and a fluorescent sheet that has undergone a special treatment is sandwiched between the electrodes to apply an AC voltage to generate electrical energy. It is a planar light-emitting body that is converted into energy and emits light. In addition, it can emit various colors such as white, green, orange, and pink, and is thin and flexible, so it can be used for flat displays such as thin advertising boards, guide boards, and menus that are mounted on the wall. There is an advantage that you can create a curved three-dimensional display.

Conventional planar light emitters are few in standard products, and most of them are ordered from the manufacturer by determining the size and the color of light emitted according to the display to be created. In this way, the factory produces according to orders, so it takes time to deliver and the price is high.
