摘要

It is an object of the present invention to provide a lighting device realizing reduction in cost and suppression of power consumption and suppressing generation of a lamp image. A lighting device 12 of the present invention includes a plurality of point light sources 80; a chassis 14 housing the point light sources 80 and having an opening 14b through which light from the point light sources 80 exits; and an optical member 15 (15a) facing the point light sources 80 and provided to cover the opening 14b. The point light sources 80 are arranged such that a light source high-density area LH where an arrangement interval thereof is relatively small and a light source low-density area LL where an arrangement interval thereof is relatively large are provided. Light reflection portions 50 reflecting lights from the point light sources 80 are formed in at least a region overlapping with the light source low-density area LL in the optical member 15 (15a).
