An object of the present invention is to suppress occurrence of uneven brightness. A lighting device 12 includes a hot cathode tube 17 that is a light source, a chassis 14 housing the hot cathode tube 17 and having an opening 14b for light from the hot cathode tube 17 to pass through, a diffuser 30 that is an optical member 15 that is provided to face the hot cathode tube 17 and cover the opening 14b, and a support member 20 supporting the diffuser 30 on a hot cathode tube 17 side. A low light reflectance portion LR is provided in a portion of the diffuser 30 that overlaps the support member 20 (support member overlapping portion). At least a surface of the low light reflectance portion LR that faces the hot cathode tube 17 has light reflectance lower than an adjacent portion ALR adjacent to the low light reflectance portion LR.
