A vacuum vessel includes a first substrate, a second substrate facing the first substrate and spaced apart therefrom, and support frames mounted along the edges of the first and the second substrates. At least two support frames are separately formed on at least one side of the first and the second substrates. Adhesive layers are placed on a surface of the support frame facing the first substrate as well as on the opposite-surface of the support frame facing the second substrate to attach the two substrates and the support frames to each other. A filler is disposed between the neighboring support frames to prevent the vacuum leakage.

An electron emission display is provided to prevent electron beams around the spacers from being distorted and to prevent arc discharging due to the spacers. The electron emission display includes first and second substrates facing each other to form a vacuum vessel, an electron emission unit provided on the first substrate, a light emission unit provided on the second substrate, and a plurality of spacers disposed between the first and the second substrates. Each spacer has a spacer body with a surface roughness, a resistance layer placed on a lateral side of the spacer body, and a flattening layer covering the resistance layer. The flattening layer has a thickness larger than the thickness of the resistance layer and a surface roughness smaller than the surface roughness of the spacer body.

An electron emission display comprises: a first plate and a second plate disposed in opposition to each other; a first electrode and a second electrode formed on the first plate and insulated from each other; an electron emission region connected to the first electrode or the second electrode for emitting electrons; a third electrode formed with at least one opening through which the electrons emitted from the electron emission region pass; a spacer supporting the first plate and the second plate so that they are spaced apart from each other; a metal coating layer formed on at least one region of the third electrode facing the spacer; a fourth electrode formed on the second plate; and a fluorescent layer connected to the fourth electrode. With this configuration, abnormal light-emission due to the spacer is prevented.
