Abstract
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.

A lighting device comprising:
- a light source unit having a light source disposed on a substrate;
- a lighted member arranged on the front side of the light source unit and lighted by an illuminating light beam from the light source;
- and
- a case member arranged between the substrate and the lighted member and includes a cavity portion provided so as to correspond to the light source,
- wherein
- the substrate is disposed so as to close an opening on a lower end side of the cavity portion and the lighted member is disposed so as to close an opening on an upper end side of the cavity portion on the side opposite from the lower end side opening, and
- the case member is formed with a heat releasing portion for releasing heat generated by the light source to the outside of the case body.
