To provide a displacement display for visually displaying a change in pressure, water levels, voltage, or the like or the degree of a change in an opening at a displacement section or a valve travel display section in equipment, such as pressure equipment, electric equipment, a water level gauge, a thermometer, and a valve.

The displacement display comprises a coupler 11 that is displaced in a straight line direction or a rotary direction by a change in a body to be measured or an opening, a casing 3, where a plurality of slits 6 at an equal width are arranged at an equal pitch, and a display member 7 that is fittingly mounted into the casing 3 so that it can be moved up and down or can be rotated and is connected to the coupler 11. A colored section 8 that is colored at least in two colors is provided at the display member 7. The amount of displacement of the coupler 11 can be decided by visually recognizing the colored section 8 exposed from the slits 6 of the casing 3.
