Electron emission display

Abstract

An electron emission display includes a first substrate and a second substrate facing the first substrate. An electron emission unit is arranged on the first substrate. A light emission unit is arranged on the second substrate, the light emission unit having an anode electrode for accelerating an electron beam emitted from the electron emission unit. A sealing member is adapted to seal an exhaust hole of the first substrate. A voltage supply unit is adapted to apply an anode voltage to the anode electrode via the sealing member.
