ABSTRACT:
A field emission display device and a fabrication method thereof, by which a vacuum sealing can be simple, and electric and optical characteristics between pixels can be improved by achieving a device package by means of a junction between substrates in vacuum without a spacer, which includes a semiconductor substrate having a groove having a predetermined depth; an n-well formed on the semiconductor substrate under the bottom of the groove; an emitter formed on the n-well; an insulation film formed on a portion of the semiconductor substrate, in which the groove is not formed; a transparent electrode bonded to the upper portion of the insulation film; a light emitting layer arranged on the upper portion of the emitter and formed within the transparent electrode; and a glass substrate formed on the transparent electrode.
