ABSTRACT:
Fluorescent tubes are arranged such that their arrangement spaces gradually become wider in central area than in edge areas, fluorescent tubes located in the vicinity of the central area of an arrangement direction are bent into chevron-shapes such that the central parts of the longitudinal directions of the fluorescent tubes become crests which provide access to a diffusion plate, respective two adjacent fluorescent tubes which are straight tubes are connected to one another, thereby constituting pseudo U-shaped tubes, and an AC power is supplied through terminals lined up along one side of a direct-type backlight device. A reflector plate is bent so as to match with the curvature of the bent fluorescent tubes, and is formed with a protrusion which allows the fluorescent tubes located in the vicinity of the central area of the arrangement direction to be raised so as to protrude toward a diffusion plate.
