发明名称 Lighting device, display device and television receiver
摘要 A lighting device includes a light source, a chassis housing the light source, and a reflection sheet provided in the chassis. The reflection sheet includes a bottom portion and a sloped portion. The bottom portion extends along a surface of the bottom plate and the sloped portion extends from a peripheral edge of the bottom portion. The sheet sloped portion is inclined with respect to the sheet bottom portion toward a light exit side of the lighting device. The reflection sheet includes a border portion and an adjacent portion. The border portion includes a borderline between the bottom portion and the sloped portion and an area along the borderline, and the adjacent portion is provided close to the border portion and on a side far away from the borderline. Light reflectance is higher in the border portion than in the adjacent portion on the surface of the reflection sheet.
