On the other hand, display devices using light sources other than fluorescent lamps are gradually being used. For example, road regulation signs and the like in which an EL (electroluminescence) panel is incorporated on the back surface are actually used. For example, there is a solar stop sign. This sign blinks the letters "stop" and the surrounding light emitting diode (hereinafter referred to as "LED"). However, signs at night do not look the same as at daytime, and there are still many accidents at the meeting at night.
