Abstract
A flat-type fluorescent lamp for LCD devices is provided, which makes it possible to narrow the picture-frame area and to widen the emission area and which facilitates their wiring, connection and assembly operations. The lamp comprises: (a) a container having a first plate, a second plate, and a frame member; the first and second plates being opposed to each other and fixed together with the frame member in such a way as to have a specific distance between the first and second plates; the first plate forming a flat emission surface; (b) a gaseous substance confined in the container; (c) a fluorescent material layer formed on an inner surface of the container; (d) electrodes formed on an inner surface of the second plate; and (e) a conductor member attached to the second plate in such a way as to extend along the inner surface of the second plate and an outer edge face thereof; a first end of the conductor member being contacted with a terminal part of the electrodes; a second end of the conductor member being located outside the second plate.
