Abstract:
A surface light source device includes a light source body having discharge spaces into which a discharge gas is injected. The light source body has a protruded portion corresponding to a remaining portion of a tip that is used for exhausting the discharge spaces and injecting a mercury gas into the discharge spaces. An electrode for applying a voltage to the discharge gas is formed on the light source body to cover the protruded portion.
