Abstract: There is provided a liquid crystal display device capable of suppressing coloring of an image when a liquid crystal panel is viewed in an oblique direction. An optical filter (4) is arranged on the front-most surface of the liquid crystal panel (11). The optical filter (4) changes transmittance when visible light of a predetermined wavelength range is emitted in an oblique direction than when emitted in the front direction. When a wide color range light source such as an LED is employed as a light source (8) of a backlight unit (12), the entire screen appears reddish and the color temperature tends to be lowered if the liquid crystal panel (11) is viewed in an oblique direction. In this case, by configuring the optical filter (4) so as to selectively attenuate the intensity of the red-based visible light range and increase the intensity of the blue-based visible light range, it is possible to suppress reddish-ness of the screen when viewed in an oblique direction.

Abstract: 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 4 is disposed at the forward end of a liquid-crystal panel 11, the optical filter 4 having 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, both of the light components having a predetermined wavelength range. In the case where a wide-color-gamut light source, such as LEDs, is used as a light sources 8 of a backlight unit 12, when the liquid-crystal panel 11 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 4 is configured such that the intensity of a visible red light component is selectively reduced and 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.

Abstract: An optical element includes an optical layer having an incident surface on which light is incident and a wavelength-selective reflective film formed in the optical layer. The optical element selectively directionally reflects light in a specific wavelength range while transmitting light in a wavelength body other than the specific wavelength body. Of light incident on the incident surface at an incident angle (¸, Æ) (where ¸: the angle between a normal to the incident surface and incident light incident on the incident surface or reflected light exiting from the incident surface; and Æ: the angle between a specific line in the incident surface and a component of the incident light or the reflected light projected on the incident surface), the optical element selectively directionally reflects the light in the specific wavelength range in a direction other than specular reflection (-¸, Æ + 180°) while transmitting the light in the wavelength range other than the specific wavelength range, and has transparency to the light in the wavelength range other than the specific wavelength range.
