    • A liquid-crystal display that can inhibit the coloring of an image when a liquid-crystal panel is viewed from an oblique direction is provided. An optical filter is disposed at the forward end of a liquid-crystal panel and has different transmittances between a light component that travels in an oblique direction and a light component that travels in a direction normal to the multilayer, where both of the light components have a predetermined wavelength range. In the case where a wide-color-gamut light source, such as LEDs, is used as a light sources of a backlight unit, when the liquid-crystal panel is viewed from an oblique direction, the entire image area tends to be reddish, and the color temperature tends to decrease. In this case, the optical filter is configured such that the intensity of a visible red light component is selectively reduced such that the intensity of a visible blue light component is increased, thereby inhibiting the reddening of an image area when viewed from an oblique direction.
    • 提供了一种从倾斜方向观看液晶面板时可抑制图像着色的液晶显示器。 滤光器设置在液晶面板的前端,并且在倾斜方向上行进的光分量与沿着垂直于多层的方向行进的光分量之间具有不同的透光率,其中两个光成分具有 预定的波长范围。 在使用诸如LED的宽色域光源作为背光单元的光源的情况下,当从倾斜方向观察液晶面板时,整个图像区域趋于变红, 并且色温趋于降低。 在这种情况下,滤光器被配置为使得可见红光分量的强度被选择性地减小,使得可见蓝光分量的强度增加,从而当从倾斜方向观察时,抑制图像区域的变红。
