Abstract: front page image
(EN)A light guide plate (11) has a light incidence surface (11c), a back surface (11b) for changing the direction of travel of the light incident from the light incidence surface (11c), and a light emission surface (11a). A plurality of dot hole parts (12) is formed on the back surface (11b), the dot hole parts (12) having inclined surfaces for changing the direction of travel of the light incident from the light incidence surface (11a). The angle (θ) formed by the back surface and the inclined surfaces of the dot hole parts (12) is 53° ≤ θ ≤ 56°.
(FR)La présente invention concerne une plaque guide de lumière (11) présentant une surface d'incidence de la lumière (11c), une surface arrière (11b) destinée à modifier la direction de déplacement de la lumière ayant frappé la surface d'incidence de la lumière (11c), et une surface d'émission de lumière (11a). Une pluralité de parties trous pointillés (12) est formée sur la surface arrière (11b), les parties trous pointillés (12) présentant des surfaces inclinées permettant de modifier la direction de déplacement de la lumière ayant frappé la surface d'incidence de la lumière (11a). L'angle (θ) formé par la surface arrière et les surfaces inclinées des parties trous pointillés (12) est tel que 53° ≤ θ ≤ 56°.
(JA) 導光板(11)は、光入射面(11c)と、光入射面(11c)から入射した光の進行方向を変更する背面(11b)と、光出射面(11a)とを有している。背面(11b)には、光入射面(11a)から入射した光の進行方向を変更する傾斜面を有する複数のドット孔部(12)が形成され、ドット孔部(12)の傾斜面と上記背面とのなす角(θ)が、53°≦θ≦56°となっている。
