Abstract
In a liquid crystal display device which uses a white LED as the light source, in order to avoid/suppress the reduction in the speed of response of the liquid crystal while increasing the color reproducibility and red chromaticity without the use of a special purpose color filter, a band cut filter which absorbs the wavelength component neighboring orange in light that is transmitted is provided between the liquid crystal display and the backlight unit.
