Since the radiation emitted from the outside is diffused by the concave lens function of the concave lens-shaped outer periphery, it can be suitably used for traffic information boards, etc., where the display must be clearly visible even in bright daylight. . Naturally, it can also be suitably used when it is desired to enhance visibility with strong light at night. Furthermore, since no expensive light source is used, the cost is low, and there is no need for complicated wiring.
