Lighting device, display device and television receiver

A lighting device, comprising:

• a light source;
• a chassis housing the light source and having an opening through which light exits;
• and
• an optical member facing the light source and provided to cover the opening, wherein:
• the chassis includes a light source arrangement area where the light source is arranged and a light source non-arrangement area where no light source is arranged;
• the optical member has a light source overlapping portion overlapping with the light source arrangement area and a light source non-overlapping portion overlapping with the light source non-arrangement area;
• the light source overlapping portion has a surface facing the light source, the surface having a light reflectance greater than that of the light source non-overlapping portion;
• the light source overlapping portion includes a low light reflectance area on a surface facing the light source, the low light reflectance area having a light reflectance smaller than that of a surrounding area in the light source overlapping portion;
• the optical member has a light reflection portion reflecting light from the light source on at least a surface of the light source overlapping portion facing the light source;
• the light reflection portion includes a dot pattern having light reflectivity;
• and
• the light reflection portion is formed such that the light reflectance of the surface of the optical member facing the light source is continuously and gradually decreased toward a direction away from the light source.
