More Information
Summary:A backlight unit that converts ultraviolet light emitted from light-emitting lamps into visible light is disclosed. The backlight unit also reflects the visible light, thus achieving improved luminance. The backlight unit includes a plurality of light-emitting lamps arranged substantially in parallel, an outer case that fixes and supports the light-emitting lamps, and a reflection sheet disposed within the outer case and containing a fluorescent material that converts ultraviolet light into visible light and reflects the visible light.
