Abstract
A backlight device having a light source, a waveguide provided close to the light source, this waveguide being a wedge-shaped waveguide so constructed that the incident light from the light source can be greatly changed in its direction and made to exit therefrom, a polarizing beam splitter provided on the light-exiting side of the wedge-shaped waveguide, and a light converter disposed on the light-exiting side of the polarizing beam splitter. This backlight device is used for liquid crystal displays.
