Abstract | A lighting device for a display device includes a plurality of linear light sources 17 arranged parallel to one another, and a light reflecting plate 14 arranged on the side of the linear light sources 17 that corresponds to the opposite side of the light emitting side. Angled reflective portions 40 each having two inclined surfaces 41, 42 are provided on the light reflecting plate 14, so as to be each positioned between adjacent linear light sources 17. The inclination angle 1 of the first inclined surface 41a of a first angled reflective portion 40a is set to be larger than the inclination angle 2 of the first inclined surface 41b of a second angled reflective portion 40b that is positioned closer to the center of the array of the linear light sources 17 than the first angled reflective portion 40a. |
