ABSTRACT:
An electron emission device includes a first substrate and a second substrate facing each other and forming a vacuum vessel. An electron emission region is provided on the first substrate, and a light-emitting region having a light-emitting area and a non-light-emitting area is provided on the second substrate. The light-emitting region includes at least one phosphor layer formed on the second substrate. At least one anode covers the phosphor layer. The anode is also positioned such that there is no gap between the anode and the non-light-emitting area. The shape of the anode in light-emitting areas follows the shape of the phosphor layer with a gap between the anode and the phosphor layer.
