PURPOSE:To reduce the color mixture of a phosphor screen forming a phosphor pattern by applying a phophor with an average grain size varying from a small one to a large one in sequence and/or with the wettability to an adhesive compound generated by exposure varying from a small one to a large one in sequence. CONSTITUTION:A phosphor with phosphor particles smaller in proportion to those of the phosphor coated in the subsequent process is coated beforehand so that the phosphor particles applied in the subsequent process do not enter the gap of a phosphor film formed in the previous process. In addition, the first color and the second color phosphor patterns are made not to be covered by an adhesive compound until the third color is coated, and if nothing is to be coated after the third color, the third color phosphor most wettable to the adhesive compound is applied. Thereby, the color mixture is prevented and the film can be made thick as much as possible. |
