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 convergence measurement apparatus for a colour CRT (1) comprises a light sensor (4) which is placed on the screen (2) of the CRT (1) to be tested, a CPU (8), and a pattern generator (15) which causes a plurality of luminescent lines of a primary colour to be displayed on one area (S1) of the screen (2) and a plane area which is a composite of the two other primary colours to be displayed on another area (S2) of the screen. The lines are shifted at a given rate along the designated area (S1) of the screen (2), the colour of the displayed lines successively changing to each primary colour. The light sensor (4) receives light intensity information from the generated pattern and the CPU (8) calculates a mis-convergence value based on the light intensity data. The apparatus further includes a self-inspection feature by which the processing is executed for successive measurements of the same primary colour. If the values for each measurement are identical, the system is assumed to be operating normally, but if there is variation, abnormal operation can be diagnosed.

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.
