Abstract
A light emission device, which can enhance degree of vacuum in a vacuum vessel by increasing an adsorption efficiency of a getter, and a display device using the light emission device for a light source are provided. The light emission device includes a vacuum vessel having first and second substrates facing each other with a predetermined distance therebetween, and a sealing member disposed between the first and second substrates and enclosing an inner space formed between the first and the second substrates. An electron emission unit is located on one side of the first substrate and having a plurality of electron emission regions. A light emission unit is located on one side of the second substrate and having an anode electrode and a phosphor layer. A getter layer is disposed on an inner surface of the sealing member that faces an inner space of the vacuum vessel.
