Abstract

PURPOSE: To have an intensive electric field which functions to accelerate an electronic beam toward a fluorescent substance layer by addding a substrate layer between the fluorescen substance layer and the substrate and making both the fluorescent layer and metallic layer extend in the electronic beam arrival direction. Thus, a good contrast picture can be obtained.
