摘要 It is an object of the present invention to provide a lighting device realizing improvement in brightness of an intended area such as a center area of an irradiation surface. A lighting device 12 of the present invention includes a light source 17, a chassis 14 housing the light source 17, and an optical member 15a facing the light source 17. The optical member 15a has a light source overlapping portion DA overlapping with a light source arrangement area LA where the light source 17 is arranged, on the chassis 14, and a light source non-overlapping portion DN overlapping with a light source non-arrangement area LN where the light source 17 is not arranged. The light source overlapping portion DA has a surface facing the light source 17, the surface having a light reflectance greater than that of the light source non-overlapping portion DN. The light source overlapping portion DA includes a low light reflectance area LR having a surface facing the light source 17, the surface having a light reflectance smaller than that of a surrounding area in the light source overlapping portion DA.
