Title:
FLUORESCENT SCREEN WITH METAL BACK AND IMAGE DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3944396
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve a withstand voltage characteristic by preventing the occurence of discharge in a fluorescent screen with a metal back of an image display device such as an FED.
SOLUTION: A covering layer including low melting point glass is arranged in an end part of a metal back layer. A projecting part of a metal back layer end part becoming a factor in generating the discharge is wrapped and covered with this covering layer. This fluorescent screen with the metal back has the metal back layer divided into blocks. The covering layer including a heat resistant inorganic particulate and the low melting point glass is straddlingly arranged in both side metal back layer end parts on a divided part of the metal back layer. The occurence of discharge is restrained. The withstand voltage characteristic can be further improved by controlling a sheet resistance value of this covering layer.
