Abstract:
1. An electron emission display, comprising: 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, a first coating layer, and a second coating layer, the first coating layer including amorphous silicon doped with p-type impurities or amorphous silicon doped with n-type impurities disposed on the spacer body and the second coating layer being an outer-most coating layer; wherein: each spacer of the plurality of spacers satisfies the proviso that 0.02<ρ2/ρ1<100, where ρ1 is a specific resistivity of the outer-most coating layer disposed on each spacer body and ρ2 is a specific resistivity of an element in direct contact with the outer-most coating layer, and the outer-most coating layer extends on the spacer body between the first and second substrates along an entire length of the spacer body.
