Abstract
A device includes a first substrate having a phosphor screen and a second substrate opposed to the first substrate across a gap and having a plurality of electron emission sources for exciting the phosphor screen. A spacer assembly for supporting an atmospheric load that acts on the first and second substrates is provided between the substrates. The spacer assembly has a plate-shaped grid and spacers set up on the grid. The volume resistance of the spacers is gradually reduced from the grid side toward the substrate side.
