ABSTRACT:
A lighting device for a display device, according to the present invention, includes a plurality of tubular light sources17arranged parallel to one another, and a light reflecting plate14arranged on the side of the tubular light sources17that corresponds to the opposite side of the light emitting side. The tubular light sources17on an inner side of the array are arranged at narrower intervals, than those on an outer side of the array. A plurality of angled reflective portions40are provided on the light reflecting plate14, so that each of the angled reflective portions is positioned between adjacent tubular light sources17and extends along the longitudinal direction of the tubular light sources17. Each angled reflective portion40includes two inclined surfaces41, 42, which face the adjacent tubular light sources17, respectively. The two inclined surfaces41, 42can reflect a larger amount of light to the outer side of a center position O between the adjacent tubular light sources17that corresponds to the outer side of the array, than to the inner side of the array.
