Abstract

An illuminating device (12) comprises a light source (17) including conductive sections (19) on its ends, an optical sheet (15) disposed on a light emitting side of the light source (17), and light-shield cover members (20) covering the ends of the light source (17), wherein each of the cover members (20) has a cover section (20z) for covering the light source (17) and an optical sheet mounting section (20a) disposed on the light emitting side of the cover section (20z) for mounting the optical sheet (15), and the optical sheet mounting section (20a) comprises a protruding section (71) protruding toward the center of the light source (17).

Description

technical field [0001] The invention relates to an illuminating device, a display device and a television receiving device. Background technique [0002] Since a liquid crystal panel used in a liquid crystal display device such as a liquid crystal television does not emit light by itself, it is necessary to separately install a backlight device as an illuminating device. Such a backlight device is known to have a structure including a plurality of backlights arranged in parallel, a lamp holder covering the ends of the backlights, and a diffuser plate arranged on the lamp holder, as disclosed in Patent Document 1, for example. The lamp holder disclosed in this patent document 1 has a function of fixing the backlight to the rear chassis, and also has a function of supporting optical sheets such as a diffuser plate. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2006-235127 [0004] In recent years, there has been an increasing demand for thinner and narrower frame...
