Abstract:
1. An electron emission device comprising: first and second substrates facing each other, unit pixels being defined on the first and the second substrates; an electron emission unit on the first substrate; phosphor layers on a surface of the second substrate facing the first substrate, each phosphor layer corresponding to at least one unit pixel, the unit pixels being arranged such that phosphor layers corresponding to like colors are aligned along a first direction of the second substrate; non-light emission regions between the phosphor layers; and spacers interposed between the first and the second substrates and arranged in the non-light emission regions, wherein the non-light emission regions include spacer loading regions loaded with the spacers and the spacers are disposed between the phosphor layers located along the first direction of the second substrate, wherein a width of the spacer loading region and a pitch of the unit pixels satisfy the following condition: A/B is less than 0.5 and greater than or equal to about 0.2 where A indicates the width of the spacer loading region and B indicates the pitch of the unit pixels located along the width of the spacer loading region, with the width of the spacer loading region and the pitch of the unit pixels being determined along the first direction of the second substrate.
