Being adhered by the long side

摘要

PROBLEM TO BE SOLVED: To provide a color cathode-ray tube preventing color unevenness by suppressing the dislocation of a shadow mask in a separating direction from a phosphor screen surface in the tube axis direction.;SOLUTION: This color cathode-ray tube is provided with a pair of long side frames 7; a pair of short side frames 14 fixed to a pair of long side frames 7 to support them in the opposed state; and the shadow mask 6 fixed in the tensile force applied state to a pair of long side frames 7. The short side frame 14 has an approximately triangular bent part formed to project on the shadow mask 6 side.;COPYRIGHT: (C)2002,JPO
