Abstract
A liquid crystal display device includes a light source that emits light having a predetermined color; a lens that concentrates the light emitted from the light source and causes the light to exit; a band-pass filter that transmits specific-band light having a specific-band wavelength in the light exiting from the lens; and a light guide plate disposed on a rear surface side of a display panel. The specific-band light transmitted through the band-pass filter is incident on a lateral surface of the light guide plate.

A liquid crystal display device comprising:
- a light source that emits light having a predetermined color;
- a lens that concentrates the light emitted from the light source and causes the light to exit;
- a band-pass filter that transmits specific-band light having a specific-band wavelength in the light exiting from the lens;
- and
- a light guide plate disposed on a rear surface side of a display panel,
- wherein the specific-band light transmitted through the band-pass filter is incident on a lateral surface of the light guide plate.
A liquid crystal display device comprising:
- a light source that emits light having a predetermined color;
- a band-pass filter that transmits specific-band light having a specific-band wavelength in the light emitted from the light source;
- a light guide plate disposed on a rear surface side of a display panel, and
- a wavelength converter that receives the light reflected by the band-pass filter in the light emitted from the light source and converts a wavelength of the received reflected light into the specific-band wavelength.
