A frame for a cathode ray tube including a panel formed with a blend region outside an effective screen of the panel, the blend region having an outer surface curvature having a radius satisfying a condition "20<=Rb<=60 (mm)" where "Rb" represents the outer surface curvature radius, so that it is possible to reduce the weight of the panel without causing a degradation in picture quality, and thus, to reduce manufacturing costs. It is also possible to reduce damage of the panel when the panel is processed in a furnace, and thus, to achieve an enhancement in productivity.
