(57) [Summary] [Object] To provide a reflective flat fluorescent lamp suitable as a light source for a liquid crystal panel. The electron beams emitted from the plurality of linear cathodes 7, 7 arranged on the cathode panel 2 hit the fluorescent film 4 on the anode panel 1 made of a metal plate and emit light. This light is reflected by the reflective film 15 on the anode panel 1 and the cathode panel 2 It is discharged from the side to the outside. At this time, the surface of the cathode panel 2 is roughened in order to make the uneven light emission inconspicuous. Further, the liquid cooling section 14 is in contact with the outer surface side of the anode panel 1 for effective cooling. |
