摘要

A lighting device 12 of the present invention includes a plurality of tubular light sources 17 arranged parallel to one another, and a light reflecting member 40 arranged on the side of the tubular light sources that corresponds to the opposite side of the light emitting side. The tubular light sources are arranged so that a narrow-interval area 17A where the arrangement interval thereof is relatively narrow and a wide-interval area 17B where the arrangement interval is relatively wide are provided. An opening section 50 is formed in the light reflecting member. The opening section 50 is provided so that the opening ratio as a ratio of the area of the opening section 50 in the entire light reflecting member 40 is higher at an area corresponding to the narrow-interval area 17A, than at an area corresponding to the wide-interval area 17B.
