To provide a reflective display device which is less damaged even when a car runs over the display device or comes into contact with the same, and is capable of reducing the cost of replacement.

The reflective display device includes an elastic thin plate 1 to which a reflective sheet is attached, and a chevron-shaped base 2 having an opening capable of fixing the thin plate 1 in a tangential direction of a curved face of a tightly-contacting end part of the base 2 by holding the thin plate 1 in the opening having a wide-mouth-like shape and bringing upper and lower parts into tight contact with the thin plate 1.
