Abstract:
(EN) A backlight device (12) is provided with: an LED (17); a chassis (14) having a bottom plate part (14a) on the opposite side from the light-emitting surface (17a) side of the LED (17), the chassis housing the LED (17); an LED substrate (18) arranged along the bottom plate part (14a), the LED (17) being mounted on the LED substrate (18); and a reflective sheet (20) for reflecting the light from the LED (17). The reflective sheet (20) has at least a bottom-side reflective part (20a) overlapping the light-emitting surface (17a) side of the LED substrate (18), and a rising reflecting part (20b) that rises from the bottom-side reflective part (20a) toward the light-emitting side. The rising base-end side portion (23) of the rising reflecting part (20b) forms a larger angle in relation to the bottom-side reflective part (20a) than the rising tip-end side portion (24) of the rising reflecting part (20a).
(FR) Un dispositif de rétroéclairage (12) comprend : une DEL (17) ; un châssis (14) ayant une partie de plaque inférieure (14a) sur le côté opposé à la surface électroluminescente (17a) de la DEL (17), le châssis logeant la DEL (17) ; un substrat de DEL (18) disposé le long de la partie de plaque inférieure (14a), la DEL (17) étant montée sur le substrat de DEL (18) ; et une feuille réfléchissante (20) permettant de réfléchir la lumière provenant de la DEL (17). La feuille réfléchissante (20) présente au moins une partie réfléchissante côté inférieur (20a) chevauchant le côté surface électroluminescente (17a) du substrat de DEL (18), et une partie réfléchissante montante (20b) qui s'élève depuis la partie réfléchissante côté inférieur (20a) vers le côté électroluminescent. La partie côté extrémité de base montante (23) de la partie réfléchissant montante (20b) forme un plus grand angle par rapport à la partie réfléchissante côté inférieur (20a) que la partie côté extrémité de pointe montante (24) de la partie réfléchissant montante (20a).
(JA) バックライト装置(12)は、LED(17)と、LED(17)の発光面(17a)側とは反対側に底板部(14a)を有しLED(17)を収容するシャーシ(14)と、LED(17)が実装され底板部(14a)に沿って配されるLED基板(18)と、LED(17)からの光を反射する反射シート(20)と、を備え、反射シート(20)は、LED基板(18)の発光面(17a)側に重なる底側反射部(20a)と、底側反射部(20a)から出光側に向けて立ち上がる立ち上がり反射部(20b)と、を少なくとも有し、立ち上がり反射部(20b)は、立ち上がり基端側部分(23)が立ち上がり先端側部分(24)よりも底側反射部(20a)に対してなす角度が大きい。
