Abstract: An electron barrier consisting of two identical shields of semirigid formed aluminum foil having forwardly bowed edges resiliently contacting the inner wall of a color picture tube panel well below frit seal line. The shadow-mask frame includes a lip cooperating with raised portions on the shields to insure flexure of the bowed edges during installation.
