Abstract A tensioned shadow mask for a cathode ray tube(CRT)comprises a series of parallel strips separated by slits at an interval, tie bars interconnecting adjacent strips and defining slits at intervals, and dummy bridges disposed between adjacent tie bars, the dummy bridges respectively extending from adjacent strips toward each other in respective slits but not interconnecting the adjacent strips. In the vertical orientation of the strips, the length of the dummy bridges is larger than the length of the tie bars.
