Abstract
An electron emission display includes an electron emission unit on a first substrate adapted to emit electron beams, a light emission unit on a second substrate, the light emission unit including a plurality of photoluminescent layers facing the electron and emission unit, a plurality of spacers between the first and second substrates along a first direction, wherein each photoluminescent layer of the plurality of photoluminescent layers satisfies a proviso that (a−b)/2>c, where 'a' is a length of the photoluminescent layer in a second direction, 'b' is a magnitude of an electron beam spot on the photoluminescent layer in the second direction, and “c” is a shifting distance of the electron beam spot in the second direction.
