ABSTRACT:
In a method for a phosphor screen of a cathode ray tube including the steps of forming a photo-tacky layer on a panel of a cathode ray tube, exposing the photo-tacky layer to form an adhesive pattern on the layer, and adhering phosphor powder on the adhesive pattern, in which these exposing and adhering steps are repeated. Before next exposing step, the photo-tacky layer is heated and then exposed after cooled. The heating step prevents the sensitivity of the layer from deterioration occurred by the preceding adhering step.
