Abstract

A surface light source includes a body, an electrode, a transparent electrode, an electron-emitting member, a conductive grid member, a fluorescent layer and a supporting part. The body includes first and second body parts spaced apart from each other. The electrode and the transparent electrode are disposed on the first and second body parts, respectively. The electron-emitting member is disposed on the electrode to emit an electron toward the transparent electrode. The conductive grid member is disposed between the electrode and the transparent electrode to accelerate the electron. The fluorescent layer is disposed on the transparent electrode to convert the electron into visible light. The supporting part is integrally formed with the body to support the first and second body parts.
