PROBLEM TO BE SOLVED: To provide a valve opening/closing state display allowing sure and visual recognition of valve opening/closing states, even if a movement distance (a difference between the quantity of appearance and disappearance) of a spindle at the center of an operation handle is small. SOLUTION: This valve opening/closing state display includes the cylindrical support body, an opening/closing state display portion, and an operation portion for operating the opening/closing condition display portion. In first and second operating members 41 and 42, one end thereof is suitable for the spindle 102, and the other end is protruded outside from a guide portion 13 of the cylindrical support body 2, bent into a dogleg-shape, and chips of first and second working line portions 41 and 42 bent into a dogleg shape are suitable for first and second display panels 31 and 32. With movement of the spindle 102 caused by rotation of the operation handle 101, the first and second operating members 41 and 42 are moved to rotate the first and second display panels 31 and 32 between an opening state and a closing state to display opening/closing state of a valve 100.
