Abstract:
A flat type fluorescent lamp comprising:a first substrate having a first fluorescent layer; a second substrate disposed parallel with the first substrate; a discharge space formed between the first and second substrates, and containing a discharge material; an electrode part having first and second electrodes parallel to each other for applying a voltage to the discharge space, the first and second electrodes being disposed on the second substrate; a plurality of barrier ribs disposed in the discharge space, the plurality of barrier ribs being perpendicular to the first and second electrodes and lower and upper surfaces of the plurality of barrier ribs respectively contacting an upper surface of the second substrate and a lower surface of the first substrate, the barrier ribs dividing the discharge space into a plurality of discharge areas; a first projection portion extended from the first electrode toward the second electrode by a first length; and a second projection portion extended from the second electrode toward the first electrode by a second length, wherein the first and second projection portions are disposed in corresponding one of the discharge areas.
