要約
(EN) Provided is a backlight device 12 equipped with: an LED 17; a light guide plate 19, a portion of an outer peripheral end surface of which constitutes a light incident end surface 19a to which light from the LED 17 enters, and one of a pair of plate surfaces of which constitutes a light output plate surface 19b from which light is emitted and the other thereof constitutes an opposite plate surface19c; an LED substrate 18 having a mounting surface 18a on which the LED 17 is mounted, the LED substrate 18 being arranged such that a portion thereof overlaps a portion of the light guide plate 19 onthe opposite plate surface 19c side; and an anchoring member 25 anchored to the mounting surface 18a in a portion of the LED substrate 18 and to the opposite plate surface 19c in a portion of the light guide plate 19, the anchoring member 25 having a light-absorbent anchoring layer 27 formed by having a light-absorbing material contained in an anchoring material.
(ZH) 背光源装置(12)具备：LED(17)；导光板(19)，其外周端面的一部分为来自LED(17)的光入射的入光端面(19a)，一对板面中的一方为使光出射的出光板面(19b)，一对板面中的另一方为相反板面(19c)；LED基板(18)，其具有安装LED(17)的安装面(18a)，以一部分在相反板面(19c)侧与导光板(19)的一部分重叠的形式配置；以及固定构件(25)，其被LED基板(18)的一部分中的安装面(18a)和导光板(19)的一部分中的相反板面(19c)固定，具有在固定材料中含有光吸收材料而成的光吸收性固定层(27)。
