Abstract

PURPOSE: To prevent the change of the stripe width or falling-off of phosphor stripes, by eliminating decomposition capacity to polyvinyl alcohol by reducing a residual periodate after forming a matrix hole.
CONSTITUTION: Photoresist is applied to an inner surface of a glass panel, and the desired location of a photoresist film is exposed and hardened, and made insoluble to developing water. A non-exposed portion is dissolution-removed by developing water to form resist stripes. A non-luminous photo-absorbing film is made up on the stripes. The resist stripes are decomposition removed by a periodate to build up a matrix hole. A phosphor is filled to the matrix hole to form phosphor stripes. When making up a fluorescent screen of a cathode-ray tube by means of such a method, a residual periodate is reduction treated by a reducing agent after building up the matrix hole, decomposition capacity to polyvinyl alcohol is removed and the change of stripe width and falling-off are prevented.
