PROBLEM TO BE SOLVED: To provide a reversible thermally color changing display body which displays various different images by temp. changes and which contributes to color changes, unexpected display, magical appearance, and various designs. SOLUTION: This reversible thermally color changing display body 1 has a thermally color changing image (A), thermally color changing image (B) and non-thermally color changing image (C) on a supporting body 2. The image (A) contains reversible thermally color changing pigments which develop colors from an color erased state by heating and which erase their colors when temp. is decreased from the color developing state. The image (B) contains reversible thermally color changing pigments which erase the colors by heating from a color developing state and develop colors by cooling from the color erased state.
