A tension mask for a color cathode-ray tube includes a plurality of strips separated by a predetermined distance and connected by real bridges. The strips define slots, through which an electron beam passes, together with the real bridges. The slots are formed such that the width of middle portions of the slots is narrower than the width of upper and lower portions of the slots in order to compensate for contraction of the strips arising when tension is applied to the strips.

The present invention describes the details of a flat mask before tension is applied, an assembling method of that flat mask, and a tension mask assembly manufactured by using that method in order to obtain satisfactory thermal expansion, uniform stress distribution and linearity. The flat mask includes an apertured portion and supporting ends surrounding the apertured portion. The apertured portion comprises a plurality of concave pin-cushion type or convex barrel type strips, a plurality of real bridges connecting strips and dividing slots, and dummy bridges formed in the slots. The short supporting ends have the same width along a longitudinal direction and are formed to have the same curvature as the strips facing the supporting ends. The short supporting ends are preferably half-etched in order to make the volume of material removed from the short supporting ends greater than the volume of material removed from the apertured portion. Therefore, the short supporting ends can have grooves on their front and rear sides. In addition, the corner portions of the supporting ends are made to have sloping sides at a predetermined angle. As a result of manufacturing the tension mask by using the method of the present invention, the apertured portions of the tension mask have satisfactory thermal expansion, uniform stress distribution and linearity. In addition, it is possible for the tension mask to be prevented from having deformation caused by heat treatment after being held under tension.
