PROBLEM TO BE SOLVED: To provide a display sheet whose visibility of the display and decoration is hardly deteriorated by wearing of the printing surface even if it is used without a protection layer for the outdoor floor whereon people walk frequently. SOLUTION: The display sheet is configured in such a way that: the surface of a base material 10 is formed into a rugged face composed of projecting parts 10a and recessed parts 10b; an arithmetic mean height (Ra) of a roughness curve under a specific cutoff value λs 0.25 mm and λc 8 mm is within the range of 10-50 μm on the surface of the base material 10; an ink layer 13 is formed of fine ink covering the projecting parts 10a and penetrating into recessed parts 10b; and an adhesive layer 15 which sticks to a floor face or a wall face is formed on the rear face of the base material 10.
