要約
(EN) [Solution] This backlight unit 20 comprises: LEDs 21; an optical sheet 24 having a light exit surface 20a for allowing light from the LEDs 21 to exit; a housing member 30 housing the LEDs 21 and the optical sheet 24; and a fixing tape 40. The housing member 30 comprises: a cyclic panel mounting surface 31 enclosing the light exit surface 20a whereon a liquid crystal panel 12 is mounted; and recessed portions 35 provided on the panel mounting surface 31 so as to be recessed. The fixing tape 40 is constituted to be ring shaped by joining together a plurality of unit fixing tapes 41A-41D, each having an elongated shape and having fixing surfaces 41a, 41b on both the front and back surfaces, the plurality of unit fixing tapes 41A-41D being joined together at positions overlapping with those of the recessed portions 35A-35D while one fixing surface 41a is fixed against the panel mounting surface 31.
(FR) L'unité de rétroéclairage selon l'invention (20) comprend: des DEL (21); une feuille optique (24) comprenant une surface d'émission de lumière (20a) permettant l'émission de la lumière provenant des DEL (21); un élément de logement (30) accueillant les DEL (21) et la feuille optique (24); et une bande de fixation (40). L'élément de logement (30) comprend: une surface de montage de panneau cyclique (31) entourant la surface d'émission de lumière (20a) sur laquelle un panneau à cristaux liquides (12) est monté; et des parties en retrait (35) disposées sur la surface de montage de panneau (31) de manière à être en retrait. La bande de fixation (40) est constituée de manière à présenter une forme annulaire par le raccordement les unes aux autres d'une pluralité de bandes de fixation d'unité (41A-41D), présentant chacune une forme allongée et comprenant des surfaces de fixation (41a, 41b) sur les deux surfaces avant et arrière, les bandes de fixation d'unité de la pluralité de bandes de fixation d'unité (41A-41D) étant assemblées les unes aux autres au niveau de positions chevauchant celles des parties en retrait (35A-35D) tandis qu'une surface de fixation (41a) est fixée contre la surface de montage de panneau (31).
