摘要
A color picture tube grid apparatus includes a mask, a frame, and a belt-like metal plate. The mask is constituted by an array of a large number of stretched grid elements defining a large number of slit holes. The frame has a pair of side frame portions for supporting the mask at two end portions of each of the grid elements in a stretching direction. The belt-like metal plate is in contact with end portions of the grid elements and arranged on at least one of two end portions of the mask to cross the array of grid elements.
