Problems solved by technology

In addition, as disclosed in Patent Document 1, when optical components such as a diffusion sheet are clamped and attached by certain components, if the frictional resistance between the components is simply reduced, shaking will occur between the clamping components. Position shift occurs, in addition, there will be adverse situations such as impact sound

Abstract

Disclosed is an illuminating device (12) comprising a light-emitting portion (15z) for emitting light, a light source (17) and an optical member (15b) arranged closer to the light-emitting portion (15z) than the light source (17). The optical member (15b) is held between a pair of holding members, and the holding member is composed of a first holding member (15a) which supports the optical member (15b) from the light source (17) side and a second holding member (16) which supports the optical member (15b) from the side opposite to the light source (17) side. A buffer member (70) is interposed at least between the optical member (15b) and the first holding member (15a) or between the optical member (15b) and the second holding member (16). A surface of the buffer member (70) which is in contact with the optical member (15b) has projections and recesses.

Description

technical field [0001] The present invention relates to an illuminating device, a display device and a television receiving device. Background technique [0002] A liquid crystal panel used in a liquid crystal display device such as a liquid crystal television does not emit light itself, so a backlight device needs to be additionally provided as an illumination device. Such a backlight device is arranged on the back side of the liquid crystal panel (the side opposite to the display surface), and has a structure of a plurality of linear light sources and a diffusion sheet (optical component) disposed on the light emitting side of the linear light sources. A backlight device is known (see Patent Document 1). [0003] [Patent Document 1] JP-A-2007-279437 [0004] In the technique disclosed in Patent Document 1, an illuminating device is disclosed, which includes a base, a reflective sheet disposed inside the base, and a diffusion sheet disposed on the light-emitting side of t...
