Abstract

The invention provides an illumination device, a display device and a television receiving device. The illumination device (12) comprises a plurality of light sources (17) and a chassis (14) for housing the light sources (17). The chassis (14) is formed of a plate member and includes a bottom portion (14a) having a flat plate shape and an outer edge portion (21) formed at an edge portion of the bottom portion (14a) and having a folded structure (31). The outer edge portion (21) includes a core member (40) disposed inside the fold of the folded structure (31) and extending along the longitudinal direction of the outer edge portion (21). By forming the outer edge portion (21) to which such core member (40) is attached, the strength of the outer edge portion (21) itself is improved, so that deformation of the chassis (14) is prevented and a uniform illumination brightness can be provided.

Description

technical field [0001] The present invention relates to an illuminating device, a display device and a television receiving device. Background technique [0002] For example, since a liquid crystal panel used in a liquid crystal display device such as a liquid crystal television cannot emit light by itself, it is necessary to separately install a backlight device as an illuminating device. This backlight device is generally arranged on the back side of the liquid crystal panel (the side opposite to the display surface), and has: a base with an opening on the liquid crystal panel side made of metal; and a plurality of lamps (such as cold cathode tubes) accommodated in the base ). [0003] In recent years, in order to meet the demand for thinner liquid crystal display devices, the thickness reduction of each component of the backlight device has been carried out. Thinning of such components leads to a decrease in the strength of the components themselves, which may lead to a...
