Abstract
An electron emission display device is constructed with first and second substrates facing each other, cathode electrodes formed on the first substrate, electron emission regions electrically connected to the cathode electrodes, and red, green and blue phosphor layers formed on a surface of the second substrate facing the first substrate. Each cathode electrode is constructed with a first electrode having opened portions arranged at the corresponding unit pixels defined on the first substrate with the same size, a second electrode spaced apart from the first electrode within the opened portion, and a resistance layer disposed between the first and the second electrodes to electrically interconnect the first and the second electrodes. The distance between the first and the second electrodes corresponding to the red, green and blue phosphor layers is established to be proportional to the light emission efficiency of the corresponding red, green and blue phosphor layers.
