Abstract
An object of the present invention is to suppress the brightness distribution in the lighting device. The backlight unitaccording to the present invention includes an LEDas a light source with a light intensity distribution in which light having a peak light intensity travels in a direction inclined with respect to a front direction, a chassishaving an opening on a light exit side and housing the LED, and a light leading memberprovided to extend from a mounting surface of the LEDtoward the light exit side. The light leading memberis configured to lead light from the LEDtoward the light exit side. The employment of the LEDwith the above light intensity distribution enables an irradiation area A irradiated with the light having the peak light intensity to be larger. This reduces the uneven that may occur in the brightness distribution of the outgoing light.
