<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device including a backlight device which is capable of illuminating the liquid crystal panel in an excellent manner even when the liquid crystal display device has a thin structure. <P>SOLUTION: The liquid crystal display device is equipped with a liquid crystal panel and a light source unit. The light source unit includes a case having an opening surface, a long tubular fluorescent tube, an electrode holder, and a cover member. The fluorescent tube and the electrode holder are provided in the case. The electrode holder is adapted to hold an electrode section formed in an edge portion of the fluorescent tube. The cover member includes a shield plate, a fixed groove and an overhanging portion. The shield plate shields the electrode holder from a diffusion area in which light emitted by a light emitting section of the fluorescent tube is scattered. The fluorescent tube extends through the fixed groove. The overhanging portion is provided at an edge of the fixed groove and on the side of the liquid crystal panel with respect to the fluorescent tube, and protrudes toward the diffusion area. A cross sectional shape of the cover member, on the side nearer to the liquid crystal panel than the overhanging portion, including the overhanging portion is different from a cross sectional shape of the cover member, on the side nearer to the liquid crystal panel than the plane including a midpoint between mutually adjacent fluorescent tubes and the overhanging portion, and parallel to the liquid crystal panel. <P>COPYRIGHT: (C)2009,JPO&INPIT |
