Electron emission display spacer and manufacturing method thereof

A method of manufacturing a spacer, the method comprising:

• forming a spacer body having a surface with a surface roughness by patterning a spacer body material;
• forming a resistance layer covering at least one lateral side of the spacer body by coating a resistant material onto the lateral side of the spacer body;
• and
• forming a flattening layer over the resistance layer, the flattening layer having a thickness larger than a thickness of the resistance layer and having a surface roughness smaller than a surface roughness of the spacer body.

An electron emission display comprising:

• a first substrate and a second substrate facing each other and together with a sealing member forming 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;
• wherein each spacer includes a spacer body having 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 having a thickness larger than a thickness of the resistance layer and having a surface roughness smaller than a surface roughness of the spacer body.
