ABSTRACT:
An electron emission display, including an electron emission unit on a first substrate, a light emission unit on a second substrate, the second substrate affixed to the first substrate and having the electron emission unit and the light emission unit positioned therebetween, and a plurality of spacers disposed between the first and second substrates, wherein each spacer of the plurality of spacers includes a spacer body and at least one coating layer disposed on the spacer body, and wherein each spacer of the plurality of spacers satisfies the proviso that 0.02<ρ2/ρ1<100, where ρ1 is a specific resistivity of an outer-most coating layer disposed on the spacer body and ρ2 is a specific resistivity of an element in direct contact with the outer-most coating layer.
