Abstract:
1. An electron emission display comprising: first and second substrates facing each other; a plurality of driving electrodes formed on the first substrate; a plurality of electron emission regions controlled by the driving electrodes; a focusing electrode disposed on and insulated from the driving electrodes and provided with openings through which electron beams pass; a plurality of phosphor layers formed on a surface of the second substrate; an anode electrode formed on surfaces of the phosphor layers; and a plurality of spacers maintaining a gap between the first and second substrates, wherein, among the electron emission regions disposed in the opening adjacent to the spacer, a first minimum distance between one electron emission region, which is closest to the adjacent spacer, and an inner wall of the opening is different from a second minimum distance between another electron emission region, which is farthest from the adjacent spacer, and the inner wall of the opening.
