Abstract:
1. A light emission device comprising: a first substrate and a second substrate facing each other to form a vacuum chamber; a first electrode arranged on the first substrate in a first direction; a second electrode arranged above the first electrode in a second direction crossing the first direction; an insulation layer interposed between the first electrode and the second electrode; an electron emission region electrically connected to one of the first electrode or the second electrode; a phosphor layer arranged on the second substrate; an anode electrode arranged on the phosphor layer; and a ground electrode in the vacuum chamber, wherein at least one of the first electrode or the second electrode is divided into a plurality of sub-electrodes, wherein a driving error sub-electrode of the plurality of sub-electrodes is electrically separated from normally driving sub-electrodes of the plurality of sub-electrodes, and wherein the driving error sub-electrode of the plurality of sub-electrodes is electrically connected to the ground electrode.
