ILLUMINATING DEVICE, DISPLAY DEVICE AND METHOD FOR MANUFACTURING ILLUMINATING DEVICE

摘要

Provided is an illuminating device wherein chromaticity fluctuation due to view angle and incidence angle is suppressed. The illuminating device for a display device is provided with a blue light emitting diode (10) as a light source, and a fluorescent sheet (21) containing a fluorescent material for obtaining white light by converting color of blue light emitted from the blue light emitting diode (10). Diffuser plates (22, 23) are arranged to face the surface on the light outgoing side and the surface on the light incoming side of the fluorescent sheet (21), respectively. The diffuser plate (22) arranged to face the surface on the light outgoing side of the fluorescent sheet (21) reduces fluctuation of white chromaticity due to view angle, and the diffuser plate (23) arranged to face the surface on the light incoming side of the fluorescent sheet (21) reduces fluctuation of white chromaticity due to incidence angle.
