A lighting device that comprises a light source unit, with light sources positioned upon a circuit substrate; an LCD panel illuminated by the light emitted from the light sources; a casing, and a diffusion member installed upon the casing. The circuit substrate is mounted so as to block the lower end aperture of the hollow portion. The diffusion member is mounted so as to block an upper end aperture of the hollow portion, which constitutes the opposite end of the hollow portion from the lower end aperture thereof. Radiation units are formed upon the casing to radiate heat caused by the light sources outside the casing.
