ABSTRACT:
An electron emission display includes a first substrate, an electron emission unit formed at the first substrate to emit electrons, a second substrate facing the first substrate, and a light emission unit formed at the second substrate to emit visible light using electrons emitted from the electron emission unit. The light emission unit includes a phosphor layer formed on the second substrate and an anode electrode formed on the phosphor layer. The anode electrode includes a first metal layer and a second metal layer formed on the first metal layer and having a single- or multi-layered structure.
