Abstract

PURPOSE:To suppress the temperature rise of a phosphor material screen, by forming black colored layers on the back face of a light reflective metal film formed on said screen and on the inner face of a funnel section. CONSTITUTION:A glass bulb 8 is constructed of a neck section 81, funnel section 82 and a face panel section 83. After forming a phosphor screen 10 on the face panel 83, a light reflectice aluminum film 13 is formed from the back face of the phosphor screen 10 to the inner face of the funnel section 82 such that its edge is lapped over a portion of a conductive film 11. A black material layer 14 having high thermal radiation factor is provided uniformly on the back face of the aluminum film 13. Consequently the thermal radiation from the phosphor material screen during the operation of the tube is improved to suppress the temperature rise of the phosphor screen and the face panel section.
