LIGHTING DEVICE, DISPLAY DEVICE AND TELEVISION RECEIVER

摘要

It is an object of the present invention to provide a lighting device including a plurality of light guide bodies in which brightness difference between light guide bodies is reduced. A backlight unit 12 according to the present invention includes a plurality of LEDs 17 as light sources and a plurality of light guide bodies 31 each having a light entrance surface 31a and a light exit surface 31b. The light entrance surface faces the light source and through which light emitted from the light source enters the light guide body. The light in the light guide body exits through the light exit surface. The light guide bodies 31 are collectively covered with a fixing member 32, so that a positional relationship between the light guide bodies 31 is constant. Further, the fixing member 32 has a relative refractive index of one or less with respect to the light guide body 31.
