Patent ID: 8223295

Claim:
A liquid-crystal display comprising: a liquid-crystal panel; a backlight unit disposed at the back side of the liquid-crystal panel, wherein the backlight unit includes a light source having a NTSC ratio of 90% or more; and an optical element comprising a dielectric multilayer including a first refractive-index material layer and a second-refractive-index material layer having a refractive index different from the refractive index of the first-refractive-index material layer, which are alternately stacked on a transparent support made of a transparent plastic film, and having different transmittances between a light component that travels in an oblique direction and a light component that emerges from the liquid-crystal panel toward the front, both of the light components being emitted from the backlight unit and having a predetermined wavelength range, wherein each of the light components having the predetermined wavelength range is a visible light component having a wavelength of 600 nm or more, and the liquid-crystal display has a transmittance for the visible light component that travels in an oblique direction lower than the transmittance for the visible light component that emerges from the outgoing-light-side face toward the front wherein the optical element has an average transmittance for a visible light component incident on the optical element at an angle of incidence ranging from 10° to 30° and having a wavelength between 400 nm to 450 nm higher than the average transmittance for a visible light component incident on the optical element at an angle of incidence of incidence of 0° and having a wavelength between 400 nm to 450 nm.
