    • A liquid crystal display device includes a backlight device, a liquid crystal panel and a light source unit. The light source unit includes a case having an opening surface, a fluorescent tube, an electric holder, and a cover member. The cover member includes a shield plate, a fixed groove and an overhanging portion, wherein the overhanging portion is provided at an edge of the fixed groove and on a side of the liquid crystal panel with respect to the fluorescent tube which includes a portion which extends through the fixed groove. A portion of the cover member includes a protrusion which is a separate member from the overhanging portion and which extends more toward the liquid crystal panel than a surface portion of the overhanging portion.
    • 液晶显示装置包括背光装置,液晶面板和光源单元。 光源单元包括具有开口表面的壳体,荧光管,电保持器和盖构件。 盖构件包括屏蔽板,固定槽和悬垂部分,其中突出部分设置在固定槽的边缘处,并且相对于荧光管设置在液晶面板的一侧,该荧光管包括延伸的部分 通过固定槽。 覆盖部件的一部分包括与突出部分分离的部件,并且比突出部分的表面部分更向液晶板延伸的突起部。

    • A liquid crystal display device includes a backlight device, a liquid crystal panel and a light source unit. The backlight device is capable of illuminating the liquid crystal panel in an excellent manner even when the liquid crystal display device has a thin structure. The light source unit includes a case having an opening surface, a 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. When a plane S1 includes the overhanging portion and is perpendicular to the surface of the liquid crystal panel, and a plane S2 includes a portion of the shield plate present between the fluorescent tubes adjacent to each other and perpendicular to the surface of the liquid crystal panel, a cross sectional shape of a portion of the cover member, which is taken along the plane S1, is different from a cross sectional shape of a portion of the cover member, which is taken along the plane S2. In this case, the portions of the cover member are located on the side of the liquid crystal panel with respect to a plane, which includes the overhanging portion and is parallel to the surface of the liquid crystal panel.
    • 液晶显示装置包括背光装置,液晶面板和光源单元。 即使液晶显示装置具有薄型结构,背光装置能够以极好的方式照亮液晶面板。 光源单元包括具有开口表面的壳体,荧光管,电极保持器和盖构件。 荧光管和电极座设置在壳体中。 电极保持器适于保持形成在荧光管的边缘部分中的电极部分。 盖构件包括屏蔽板,固定槽和悬伸部分。 屏蔽板将电极保持器屏蔽在由荧光管的发光部分发射的光散射的扩散区域中。 荧光管延伸穿过固定槽。 突出部设置在固定槽的边缘处,并且相对于荧光管设置在液晶面板的一侧,并且朝向扩散区域突出。 当平面S1包括悬垂部分并且垂直于液晶面板的表面时,平面S2包括存在于彼此相邻并且垂直于液晶面板的表面的荧光管之间的屏蔽板的一部分 沿着平面S1截取的盖构件的一部分的横截面形状与沿着平面S2截取的盖构件的一部分的横截面形状不同。 在这种情况下,盖构件的部分相对于包括突出部分并且平行于液晶面板的平面的平面位于液晶面板的侧面。
