METAL MEMBER FOR IMAGE DISPLAY DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a member for an image display device having a phosphor for obtaining a high luminance and high definition image display device, and to provide a method for forming the member for an image display device with high precision and high speed, at a low cost. SOLUTION: The member for an image display device has the phosphor formed on a metal substrate. The phosphor contains Y2O3as a main component, and has a fluorescence intensity of 500au or higher in at least part of the visible light region, measured by a fluorescence analyzer. A method for manufacturing the member for an image display device comprises forming the phosphor on the substrate using a vapor deposition method in an open-to-atmosphere condition.
