A mask assembly for a cathode ray tube includes a tension mask having an effective portion formed with strips spaced apart from each other forming slots there between and a non-effective portion surrounding the effective portion. A mask frame includes a pair of supporting members along long sides of the tension mask and a pair of elastic members spacing the supporting members from each other by a predetermined distance. Vibration damping members damp vibration of the tension mask, where the vibration damping members are tensioned in a longitudinal direction to pressurize the non-effective portion.
