Abstract
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.
