<p>A spacer and an electron emission display device having the same are provided to suppress the variations of electric field around the spacer even if electrons emitted from electron emission portions collide against a surface of the spacer. A spacer is interposed between a first substrate(10) and a second substrate(12) which form a vacuum envelope. A preform(22) is made of dielectric and has a certain height along a thickness direction of the first and second substrates. A thermal conducting layer(26) is formed on a portion of a surface of the preform, and is spaced apart from electrodes formed on the first and second substrates. A secondary electron emission layer(24) is formed on the entire surface of the preform to cover the thermal conducting layer.</p> |
