A light emission having: a first substrate; a second substrate opposite the first substrate; a sealing member between the first and second substrates and forming a vacuum envelope with the first and second substrates. The device also includes an electron emission unit on the first substrate, the electron emission unit having a plurality of pixel regions, each of the plurality of pixel regions having an independently controlled electron emission; a light emission unit on the second substrate, the light emission unit having a phosphor layer and an anode electrode on the phosphor layer; at least one anode button penetrating the second substrate at a region enclosed by the sealing member and spaced apart from the light emission unit; and a conductive layer on the second substrate and electrically coupling the anode button to the anode electrode.
