Electron emission display spacer with flattening layer and manufacturing method thereof
摘要:
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.
