A flat fluorescent lamp has a vessel or housing including first and second substrates opposed to each other at a small distance, and having discharge gas enclosed therein. A first planar electrode layer being transparent is disposed on an inner surface of the first substrate. A second planar electrode layer is disposed on an inner surface of the second substrate, for electrical discharge in cooperation with the first planar electrode layer. First and second dielectric layers are disposed on respectively the inner surfaces of the first and second substrates to cover the first and second planar electrode layers. First and second fluorescent layers are overlaid on respectively inner surfaces of the first and second dielectric layers, for emitting electromagnetic rays upon the electrical discharge between the first and second planar electrode layers. A pattern of plural projections is formed with the inner surface of the second dielectric layer.
