PROBLEM TO BE SOLVED: To prevent generation of a bright line by excluding unnecessary thickness due to a reflector and eliminating light leakage. SOLUTION: A first reflection plate 1, provided with a back surface part 1c placed at the back surface side of a linear light source 9, an upper surface part 1b placed at its upper surface side and a bent part 1a corresponding to an edge part of the upper surface part 1b, is attached inside a light source cover 8. A second reflection plate 2, arranged at the lower side of a light transmission plate 3, is provided with an extended part 2b extending from an edge surface to the light source side. A reflection part (a reflector) for the light source is constructed with the first reflection plate 1 and the extended part 2b of the second reflection plate 2 by providing the light source cover 8 to the linear light source 9 as a top covering. |
