IMAGE DISPLAY

摘要

An image display comprising a face plate (6) whose inner surface is provided with a phosphor screen and a rear plate having many electron-emitting devices is disclosed. The phosphor screen comprises a light-absorbing layer (8), a phosphor layer (9), a metal back layer (10) which has a separating portion (10a) and is formed on the phosphor layer, a high-resistance covering layer (11) which is so formed across the separating portion of the metal back layer as to extend over the metal back layer on both sides of the separating portion, a heat-resistant fine particle layer (12) formed on the high-resistance covering layer, and a getter layer (13) which is formed as a film lying over the metal back layer and divided by the heat-resistant fine particle layer. Consequently, by improving heat resistance characteristics, breakage and deterioration of the electron-emitting devices or the phosphor screen due to abnormal discharge can be prevented in an image display such as an FED, and thus a high-luminance, high-quality display can be realized.
