摘要： 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.

摘要： A liquid crystal display comprising an absorption polarizer disposed on the viewed side of a liquid crystal cell and a reflection polarizer disposed on the opposite side. The liquid crystal cell holds a liquid crystal between two transparent substrates each provided with an electrode on the opposite inner surface thereof. The absorption polarizer is a polarizing sheet absorbing a linearly polarized light having a plane of vibration perpendicular to the axis of easy transmission, whereas the reflection polarizer is a polarizing sheet reflecting the linearly polarized light. A reflector or a color filter is preferably disposed under the reflection polarizer, and a light diffusion layer or a light diffusion plate is preferably disposed on the viewed side of the absorption polarizer.

摘要： A display system having a non-absorbing and reflective color filtering array and a reflector to improve light utilization efficiency. One implementation of the color filtering array uses a surface plasmon filter having two symmetric metaldielectric interfaces coupled with each other to produce a transmission optical wave at a surface plasmon resonance wavelength at one interface from a p-polarized input beam on the other interface. Another implementation of the color filtering array uses a metal-film interference filter having two dielectric layers (320) and three metallic films (310a, b).

摘要： The invention is an improvement in a liquid crystal display device of the type having spaced front (10) and rear (12) glass panels, a transparent electrode layer (18), and an array of individually addressable pel electrodes (20) separated from the transparent electrode layer by a cavity filled with liquid crystal material (30). The improvement comprises a color filter layer in the form of a decal pattern (22). The decal pattern (22) is formed using interference film techniques which form an inorganic color filter. The decal is placed on one of the glass panels using known decal transfer methods. The inorganic nature of the color filter layer and the decal transfer methods allow for enhanced optical density of the color liquid crystal display.

摘要： A display apparatus includes a light source which generates a first light, a display module which displays an image, a light guide plate disposed under the display module, and an optical filter disposed under the light guide plate to face the display module. The optical filter includes a filter layer which transmits a portion of the first light from the light guide plate and reflects a remaining portion of the first light except for the portion and an absorbing layer disposed under the filter layer to absorb the first light transmitted thereto through the filter layer. As an incident angle of the first light incident to the filter layer with respect to a normal line of an upper surface of the filter layer increases, an overlapping bandwidth between a reflection wavelength bandwidth of the filter layer and a wavelength bandwidth of the first light increases.
