Title: Inner shield for a cathode ray tube and method for manufacturing the same

Abstract: An inner shield for a cathode ray tube comprising a plurality of rectangular segments parallel to the tube axis; a flange joined to each of the rectangular segments and bent in a right angle for mounting on a mask frame; a trapezoid portion joined to each of the rectangular segments, being arranged slantwise along an inner circumference of a funnel; and a pair of holes formed in the two adjacent trapezoid portions to decrease a deflection in a East-West direction of an electron beams. Since an undesirable affection on the electron beams caused by the earth magnetic field is decreased, a pin-cushion distortion and barrel distortion of the electron beams are highly decreased.
