A grid structure for a color cathode ray tube comprises a substantially rectangular, one-piece frame consisting of a pair of first opposed frame portions and a pair of second opposed frame portions orthogonally related to the first frame portions and being integral with the latter at ends thereof, and grid elements secured to the first frame portions and extending therebetween generally parallel to the second frame portions in a longitudinally stressed condition, the second frame portions having at least recesses therein for enhancing the resilient bending thereof under loads applied to the first frame portions in directions urging the latter toward each other. |
