Backlight unit and liquid crystal display |
| abstract |
Disclosed are a backlight unit and a liquid crystal display capable of improving viewing angle dependency of tint of a liquid crystal display image, thereby obtaining a high-quality liquid crystal display image with no tint when viewed from a slanting direction. A backlight unit 200 of a just-beneath type with a plurality of light sources arranged below a light emission surface 38 includes a light emission spectrum controlling unit 53 for controlling separately light emission spectra in a front direction which becomes a normal direction to the light emission surface 38 and a slanting direction inclined at a predetermined angle from the front direction. The plurality of light sources are a plurality of LED light sources which are different in a light emission color, and each LED light source includes a first LED element with the front direction as an optical axis of emission light and a second LED element with the slanting direction as an optical axis of emission light for each light emission color. The light emission spectrum controlling unit 53 changes light emission intensity of the second LED element for each light emission color. |
