Title (EN) DISPLAY DEVICE, ELECTRONIC APPARATUS, AND LIGHT GUIDE UNIT
(FR) DISPOSITIF D'AFFICHAGE, APPAREIL ÉLECTRONIQUE ET UNITÉ DE GUIDAGE DE LUMIÈRE
(JA) 表示装置及び電子機器並びに導光ユニット
Abstract:
(EN) A display device (1) is provided with a panel (91), a substrate (2), a light-emitting element (3), and a light guide medium (4). The substrate (2) is disposed so as to butt against the back face of the panel (91). The light-emitting element (3) is disposed on the substrate (2) so as to emit light toward the panel (9) in parallel to the substrate (2). The light guide medium (4) receives light from the light-emitting element (3) and, as an output, guides the light to the front side of the panel (91). The light guide medium (4) is further characterized by being held between the end surface of the substrate (2) and the back surface of the panel (91).
(FR) L'invention concerne un dispositif d'affichage (1) pourvu d'un panneau (91), d'un substrat (2), d'un élément électroluminescent (3) et d'un support de guidage de lumière (4). Le substrat (2) est disposé de façon à buter contre la face arrière du panneau (91). L'élément électroluminescent (3) est disposé sur le substrat (2) de façon à émettre de la lumière en direction du panneau (9) parallèlement au substrat (2). Le support de guidage de lumière (4) reçoit de la lumière provenant de l'élément électroluminescent (3) et, en tant que sortie, guide la lumière vers le côté avant du panneau (91). Le support de guidage de lumière (4) est en outre caractérisé en ce qu'il est maintenu entre la surface d'extrémité du substrat (2) et la surface arrière du panneau (91).
(JA) 表示装置(1)は、パネル(91)と、基板(2)と、発光素子(3)と、導光体(4)と、を備えている。基板(2)は、パネル(91)の背面に対して突き当たるように配置されている。発光素子(3)は、基板(2)上に、該基板(2)に平行にパネル(91)に向けて光を発するように配置されている。導光体(4)は、発光素子(3)からの光が入り、該光を前記パネル(91)の前面側に導いて出力する。さらに、導光体(4)は、基板(2)の端面とパネル(91)の背面との間に挟まれて配置されていることを特徴とする。
