PROBLEM TO BE SOLVED: To provide a laminated display body whose pattern layer can not be recognized in a light place, but can be recognized in a dark place. SOLUTION: The laminated body is constituted by forming the pattern layer 2 on a base sheet 3 and forming a luminous layer 1 on the base sheet and pattern layer. The luminous layer is less in film thickness on the light pattern layer than at the circumference of the pattern layer, so the pattern layer is visible in a dark place by generating a difference in intensity of light emission by the difference in film thickness of the luminous layer and is hidden behind the luminous flux when no light is emitted the pattern layer is made invisible in a light place.
