A backlight device 12 includes cold cathode tubes 17, a chassis that houses the cold cathode tubes 17 therein and having an opening 14b through which light emitted from the cold cathode tubes exits, and a diffuser plate 15 provided so as to face the cold cathode tubes 17 and cover the opening 14b. A light reflecting portion 30 is formed on a side of the diffuser plate 15 close to the cold cathode tubes 17 so as to have different light reflectance in every surface area of a surface of the diffuser plate 15. A scattering structure 31 is formed on a side of the diffuser plate 15 opposite from the cold cathode tubes 17 and scatters the light. |
