ABSTRACT:
A display device having a pattern of conductors recessed on an electrode, thus reducing the risk of the pattern of conductors being damaged such as from a surface scratch. When the pattern of conductors and the plate are separated from each other by an insulating layer, the pattern of conductors screens the insulating layer from the electron beam. The method is characterized in that grooves are formed between the apertures, and an insulating layer and conducting layer are provided on the walls of the apertures and the grooves.
