PROBLEM TO BE SOLVED: To obtain a reversible heat-sensitive storage sheet in which a pattern being formed on the lower side of a reversible heat-sensitive storage layer and an OVD are made visible, and a display storage medium using the same. SOLUTION: In a reversible heat-sensitive storage sheet where at least a reflection layer 2, and a transparent/cloudy reversible heat-sensitive storage layer 4 where an organic low molecule is dispersed in a resin base material are provided, at least one part of the reflection layer 2 is discontinuously provided, thus obtaining the reversible heat-sensitive storage sheet where a scene and a pattern can be seen and recognized via the reversible heat-sensitive storage sheet when the reversible heat-sensitive storage layer 4 is made transparent, and a display storage medium where the reversible heat-sensitive storage sheet is formed in one piece at the upper side of at least one part of a card medium. |
