In an image display device having in an airtight container an electron source and an image display member that receives electrons from the electron source, an evaporating getter and a non-evaporating getter are stacked in the airtight container. This makes it possible to maintain the vacuum level in the airtight container. The image display device thus obtains a prolonged life and a stable display operation.

Method of manufacturing image display device by stacking an evaporating getter and a non-evaporating getter on an image display member

A novel process for producing an electron source substrate is disclosed for formation of electron-emitting element at high efficiency with less shape irregularity. In the process, the region for electroconductive film formation is divided into plural subregions on which an electroconductive film is formed respectively. In forming the electroconductive film by application of plural liquids, the time interval between the application of the two drops is controlled to be larger than the time length necessary for suppressing the spreading of the succeedingly applied liquid within an allowable limit.
