Abstract
A fluorescent screen display panel includes selectively deposited fluorescent material on a plurality of color-coated transparent electrodes that are formed on a base member. A spacer support layer is formed on the base member between groups of the color-coated transparent electrodes and a further electrode is formed on the spacer support layer. The further electrode is not coated with fluorescent material. Spacer members that support a display panel are also formed on the spacer support layer.
