Abstract:
(EN) A backlight device (12) which configures a liquid crystal display device (10) is provided with: an LED (16), i.e., a light source; a light guide plate (18) having a light incoming surface (18b), which faces the LED (16) and permits light to enter the surface, and a light outgoing surface (18c), which is disposed parallel to the light incoming surface (18b) and outputs light therefrom; a first light scattering structure (23) which is disposed on the light incoming surface (18b) and scatters light; and a light reflecting section (24) which is disposed on the light outgoing surface (18c) and reflects light.
(FR) L'invention porte sur un dispositif de rétroéclairage (12) qui configure un dispositif d'affichage à cristaux liquides (10) qui comporte : une DEL (16), à savoir une source de lumière ; une plaque de guide de lumière (18) ayant une surface d'incidence de lumière (18b), qui fait face à la DEL (16) et permet à la lumière de pénétrer la surface, et une surface de sortie de lumière (18c), qui est disposée parallèle à la surface d'incidence de lumière (18b) et émet de la lumière à partir de celle-ci ; une première structure de diffusion de lumière (23) qui est disposée sur la surface d'incidence de lumière (18b) et diffuse la lumière ; et une section réfléchissant la lumière (24) qui est disposée sur la surface de sortie de lumière (18c) et réfléchit la lumière.
(JA) 液晶表示装置10を構成するバックライト装置12は、光源であるLED16と、LED16に対向し光が入射される光入射面18b、及び光入射面18bに沿って並行するとともに光を出射させる光出射面18cを有する導光板18と、上記した光入射面18bに配され、光を散乱させる第1光散乱構造23と、上記した光出射面18cに配され、光を反射させる光反射部24とを備える。
