摘要
A mercury light source tube such that a detrimental effect on its lifetime caused by gathering of mercury at peripheral portions of electrodes can be prevented or controlled, a light source device, and a display device. The mercury light source tube has a tube body in which mercury is sealed, electrodes provided to the tube body, and projections provided on an outer surface of the tube body to be integral with the tube body. The projections are placed between the electrodes or in positions at a distance from the electrodes toward the tube body center. The projections locally increase the surface area of the tube body so as to easily radiate heat to the outside, and locally decrease temperatures of the positions where the projections are placed and their peripheral portions so that mercury gathers at the low temperature portions.
