A spacer (300), disposed between first and second substrates (20,10) of an electron emission display, includes a main body (310), a resistive layer arranged on a side surface of the main body (321), a secondary electron emission preventing layer arranged on the resistive layer (323), and a diffusion preventing layer arranged between the resistive layer and the secondary electron emission layer (322). The diffusion preventing layer prevents interdiffusion between the resistive layer and the secondary electron emission preventing layer.
