ABSTRACT:
To manufacture a cathode-ray projection tube, a glass face panel with a skirt portion is provided. The glass face panel is formed to satisfy the following formula 0.85.ltoreq.B/A, where A is a long edge length of the inner surface of the glass face panel and B is a short edge length of the inner surface of the glass face panel. Then, high and low refraction materials are alternately evaporated to form an optical multiple layered interference film having a substantially uniform thickness on the inner surface of the glass face panel.
