A light emission device and a display device provided with the light emission device. The light emission device includes first and second substrates opposing each other; a side member located between periphery regions of the first and second substrates to define a vacuum chamber with the first and second substrates; an electron emission unit disposed on the first substrate; and a light emission unit disposed on the second substrate and adapted to emit light using electrons emitted from the electron emission unit. The light emission unit includes a phosphor layer and an anode electrode disposed on a surface of the phosphor layer, and the anode electrode is applied with a voltage through an anode terminal penetrating through the side member.
