Provided is a technique for appropriately securing a light source substrate without using screws. A backlight device (12) is provided with an LED substrate (18) having an LED (17) which is the light source; a chassis (14) which houses the LED substrate (18) and has an aperture (14b) for emitting light from the LED (17); an optical member (15) which is arranged in a shape that covers the aperture (14b) so as to lie opposite the LED substrate (18); and a support member (20) which supports the optical member (15) from the LED substrate (18) side. The support member (20) is secured to the chassis (14) with the LED substrate (18) sandwiched in between said support member (20) and the chassis (14).
