Title (EN) ILLUMINATION DEVICE AND LIQUID CRYSTAL DISPLAY APPARATUS
(FR) DISPOSITIF D'ÉCLAIRAGE ET APPAREIL D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 照明装置及び液晶表示装置
Abstract:
(EN) Obtained are an illumination device and a liquid crystal display apparatus that are capable of reducing unevenness of illumination light and/or generation of a hotspot. The illumination device is characterized by comprising: a light source unit (10) that emits illumination light in the optical axis direction; a primary reflective part that reflects the illumination light, which has been emitted by the light source unit (10), toward the surroundings of the light source unit (10) and in a direction away from the optical axis direction; a secondary reflective part that is composed of a group of sheets capable of being combined with each other in the surroundings of the light source unit (10) and that further reflects the illumination light, which has been reflected by the primary reflective part, in a direction away from the optical axis direction.
(FR) L'invention concerne un dispositif d'éclairage et un appareil d'affichage à cristaux liquides qui sont susceptibles de réduire les irrégularités d'une lumière d'éclairage et/ou la génération d'un point chaud. Le dispositif d'éclairage est caractérisé en ce qu'il comprend : une unité de source de lumière (10) qui émet une lumière d'éclairage dans la direction d'axe optique; une partie réfléchissante primaire qui réfléchit la lumière d'éclairage, qui a été émise par l'unité de source de lumière (10), en direction de l'environnement de l'unité de source de lumière (10) et dans une direction opposée à la direction d'axe optique; une partie réfléchissante secondaire qui est composée d'un groupe de feuilles pouvant être combinées les unes avec les autres dans l'environnement de l'unité de source de lumière (10) et qui réfléchit davantage la lumière d'éclairage, qui a été réfléchie par la partie réfléchissante primaire, dans une direction opposée à la direction d'axe optique.
(JA) 照明光のムラ、及び/又は、ホットスポットの発生を低減することができる照明装置及び液晶表示装置が得られる。 照明光を光軸方向に出射する光源部(10)と、光源部(10)が出射した照明光を、光源部(10)の周辺部に向けて且つ光軸方向から離間する方向に反射する一次反射部と、光源部(10)の周辺部で互いに組み合わせられるシート群から構成され、一次反射部が反射した照明光を、光軸方向から離間する方向にさらに反射する二次反射部と、を有することを特徴とする照明装置。
