Abstract
PURPOSE:To obtain a shadow mask at a low cost by fixing the shadow mask on a mask frame in a condition that compression forces are applied in one axial direction of the mask frame to fix it, before removing the compression force to tensely lay the shadow mask on the frame by a restoring force in the axial direction. CONSTITUTION:In a condition that compression force 26, 27 are applied to a mask frame 25 in one axial direction to fix it, a shadow mask 24 is fixed to a pair of edges of the mask frame 25, after that, the compression forces 26, 27 are canceled, then the shadow mask 24 is tensely laid by a restoring force of the mask frame 25. Accordingly, jigs, devices further operation processes needed to carry out this process are simple and easy so that a tension mask with a low manufacturing cost can be obtained.
