ABSTRACT:
A storage target capable of storing an electric charge corresponding to an input signal and also converting the stored charge image into a visible form is provided on the inner wall of a faceplate closing the opening of a funnel constituting an evelope of a direct-viewing storage tube. The storage target includes a collector electrode formed on the inner wall of the faceplate; a plurality of fluorescent dot islands provided in contact with the collector electrode; and a dielectric material formed between those of the fluorescent dot islands which are arranged on the outermost peripheral edge of the storage target and a sealed portion joining the opening of the funnel and the faceplate so as to face the collector electrode and surround the effective area of the storage target, thereby preventing the luminescence of that portion of the target which is positioned around the peripheral edge of the effective area of the storage target.
