Title (EN) BACKLIGHT DEVICE
(FR) DISPOSITIF RETROECLAIRE
(JA) バックライト装置
Abstract:
(EN) In a side light-type backlight device where a light source section is provided at a side end face of a light guide plate, an optical reflection coating film having light resistance and heat radiation ability is provided on the inner surface of the reflector. In a directly under-type backlight device that has a lamp house and light emission sources arranged inside the lamp house, the optical reflection coating film is provided on the inner surface of the lamp house. The structures above provide backlight devices and liquid crystal display devices capable of maintaining display quality over a long period.
(FR) Selon la présente invention, dans un dispositif rétroéclairé de type à éclairage latéral, dans lequel une section de source de lumière se trouve au niveau d'une extrémité latérale d'une plaque de guidage de lumière, un film de revêtement de réflexion optique doté d'une résistance à la lumière et d'une capacité de rayonnement thermique se situe sur la surface interne du réflecteur. Dans un dispositif rétroéclairé directement par en-dessous qui possède une boîte à lumière et des sources d'émission de lumière placées à l'intérieur de ladite boîte, le film de revêtement de réflexion optique se situe sur la surface interne de la boîte à lumière. Les structures susmentionnées permettent d'engendrer des dispositifs rétroéclairés et des dispositifs d'affichage à cristaux liquides capables de maintenir une certaine qualité d'affichage au cours d'une longue période.
(JA)  導光板の側端面に光源部が配置されたサイドライト型のバックライト装置では、そのリフレクタの内面に、また、ランプハウスとその内部に設置された複数の発光源とを備えた直下型のバックライト装置では、そのランプハウスの内面に、耐光性および熱放射性を有する光学反射塗膜が形成されている。これによって、長期にわたって表示品質が維持されるバックライト装置および液晶表示装置が提供される。
