Abstract

PURPOSE:To ensure the thermal correction of mask without requiring bimetal, by taking displaceable for the shadow mask fastening part and the arm linking the stud coupling part, through the axis provided with the stright line passing through the center of coupling hole. CONSTITUTION:The shadow mask support material 20 having elasticity cnsists of the shadow mask fastening part 21, astud coupling part 22 providing the stud coupling hole 24 coupled with the stude 6 implanted to the pannel surface, and the same 23 linking those. The arm 23 is tilted by a given angle beta with the coupling part 22 and it is formed so that it causes displacement by taking the straight line 25 passing through the center of the coupling hole 24. Further, by setting the angle beta as 45 deg., when the mask thermally expands due to temperature rise, displacement is taken place by taking the straight line 25 as the center for the mask, and mis- landing can be prevented, for the fluorescent video element by electron rays through pushing up of it toward the panel surface for the specified position.
