Abstract
(EN) Provided are a light source device capable of maintaining the display quality to a satisfactory level, and a display device equipped with the light source device. The present invention is the light source device comprising a strip-shaped base plate whereon a plurality of light sources are mounted, a light-guide plate disposed in such a manner that one edge surface thereof faces the light-emitting diode mounted surface of the base plate, and a plurality of spacers provided in the spaces between the plurality of light sources on the base plate while being intercalated between the light-guide plate and the mounting surface of the base plate, wherein the plurality of spacers comprise a material having the same coefficient of thermal expansion as that of the light-guide plate, and the one edge surface of the light-guide plate being provided with a plurality of recessed portions whereinto the plurality of spacers engage respectively.
(FR) L'invention concerne un dispositif de source de lumière capable de maintenir la qualité d'affichage à un niveau satisfaisant, et un dispositif d'affichage équipé du dispositif de source de lumière. La présente invention concerne un dispositif de source de lumière comprenant une plaque de base en forme de bande sur laquelle est montée une pluralité de sources de lumière, une plaque de guidage de lumière disposée de telle manière qu'une surface de bord de celle-ci fait face à la surface de montage de diode électroluminescente de la plaque de base, et une pluralité d'entretoises disposée dans les espaces entre la pluralité de sources de lumière sur la plaque de base tout en étant intercalée entre la plaque de guidage de lumière et la surface de montage de la plaque de base, laquelle pluralité d'entretoises comprend un matériau ayant le même coefficient de dilatation thermique que celui de la plaque de guidage de lumière, et ladite surface de bord de la plaque de guidage de lumière étant pourvue d'une pluralité de parties en retrait dans laquelle la pluralité d'entretoises vient respectivement en prise.
(JA)  表示品位を良好に保つことができる光源装置及び該光源装置を備える表示装置を提供する。 複数の光源が実装されている短冊状の基板と、該基板の前記発光ダイオードの実装面に一側面を対向させて配された導光板と、前記基板上の前記複数の光源間に設けられ、前記導光板と前記基板の実装面との間に介在する複数のスペーサとを備える光源装置において、前記複数のスペーサは、前記導光板と同じ熱膨張係数を有する材料からなり、前記導光板の前記一側面には、前記複数のスペーサが夫々嵌入する複数の凹部が設けられている。
