Abstract

The front panel of an image display device is provided with a plurality of phosphor layers (6) formed on a glass board (4); a plurality of light absorbing layers (5) provided between the phosphor layers, respectively; a metal back layer (1), which is formed on the phosphor layers and is electrically divided into a plurality of pieces; a plurality of getter dividing layers (2), which are formed on the light absorbing layers by depositing an insulator as a cliff-shaped deposit having a wall surface formed within a range of 90 to 80 degrees to a metal back layer surface; and a plurality of getter layers (3) wherein the getter layer on the metal back layer and the getter layer on the getter dividing layer (2) are electrically insulated by being stacked on the metal back layer and the getter dividing layer, respectively. The getter layer formed on the getter dividing layer and the getter layer formed on the metal back layer are sufficiently separated, discharge chaining is prevented and the image display device having excellent operation stability is provided.

Description

technical field [0001] The present invention relates to a flat panel image display device such as a field emission display (FED) and a method of manufacturing such a display. Background technique [0002] In recent years, flat-panel image forming devices have been developed. In this flat panel image forming apparatus, it is necessary to electrically separate the metal liner on the front substrate with a predetermined pattern in order to suppress discharge current when a discharge occurs between the front substrate and the rear substrate in the fluorescent surface structure. Also, it is a common process to form a degassing film on the metal liner of the front substrate to maintain a high vacuum between the front substrate and the rear substrate. Here, however, since the degassing layer is electrically conductive, it is necessary to separate it electrically as in the case of the metal liner described above.
