    摘要: Horizontal line misconvergences produced at screen upper and lower portions, among rasters displayed by side electron beams are corrected without producing degradation in vertical deflection sensitivity so much and changing horizontal trapezoidal distortion. In a deflection yoke provided with a top-and-bottom pair of saddle-type horizontal deflection coils and a right-and-left pair of saddle-type deflection coils and mounted to and used in a color cathode ray tube having an in-line arranged electron gun, a pair of sub-cores is provided from side to side or above and below on the electron gun side of the deflection yoke. At least one pair of correction coils is wound around each of the pair of sub-cores. The one pair of correction coils is connected in series with vertical deflection coils in such a manner that respective magnetic poles produced from the one pair of correction coils become identical to the pole of a cathode ray tube axis, and a variable resistor is connected in parallel with the one pair of correction coils to change a current that flows through the one pair of correction coils.

    摘要: A liquid crystal display panel formed by using a TFT substrate and a color filter substrate is polished to decrease the thickness thereof so that it can be curved. The liquid crystal display panel and various optical sheets are sandwiched between a frame forming a curved surface and a light guide plate forming a curved surface, to thereby form a curved surface. An upper polarizer plate and a lower polarizer plate are, respectively, sandwiched between the surface cover and the liquid crystal display panel, and between the liquid crystal display panel and the optical sheet, and are not adhered or are partly adhered to the liquid crystal display panel.

    摘要: The present invention provides a liquid crystal display device which can largely enhance a property of focusing light from a backlight. The backlight arranged on a back surface of a liquid crystal panel includes a light guide plate, a light source, a first asymmetrical prism sheet, and a second asymmetrical prism sheet. A reflection surface having an inclination of 2° or less for guiding light from the light source toward the liquid crystal display panel is formed on a back surface of the light guide plate. The first asymmetrical prism sheet and the second asymmetrical prism sheet respectively include projecting portions which extend in the arrangement direction of the light source and are arranged in parallel to each other in the direction which intersects the arrangement direction of the light source.

    摘要: A panel unit is formed by sandwiching a liquid crystal display panel and a diffusion sheet between a front surface plate having a curved plane and a back surface plate having a curved plane. A light source unit is arranged on a back surface of the panel unit. The diffusion sheet is formed into an outward convex shape in the same manner as the liquid crystal display panel and hence, due to a lens action of the diffusion sheet, light from the light source unit is collected in the direction toward the center of a screen. Accordingly, it is possible to suppress a phenomenon that brightness in a periphery of the screen is reduced when the screen is viewed from a front side.

A light source unit is arranged on a back surface of the panel unit. The diffusion sheet is formed in to an outward convex shape in the same manner as the liquid crystal display panel and hence, due to a lens action of the diffusion sheet, light from the light source unit is collected in the direction toward the center of a screen. Accordingly, it is possible to suppress a phenomenon that brightness in a periphery of the screen is reduced when the screen is viewed from a front side.

    摘要: The present invention provides a liquid crystal display device of high quality having high brightness and uniform brightness distribution by focusing the light radiation direction from a light guide plate in the vertical direction with respect to a light radiation surface of the light guide plate. The liquid crystal display device includes a liquid crystal display panel and a flat lighting device which radiates an illumination light to a back surface of the liquid crystal display panel. The flat lighting device includes a light guide plate which has an upper surface facing a back surface of the liquid crystal display panel in an opposed manner and constituting a light radiation surface and a bottom surface which is arranged opposite to the upper surface. One LED is arranged at a first corner portion of the light guide plate and another LED is arranged at a second corner portion of the light guide plate arranged adjacent to the first corner portion. By forming reflection surfaces which are inclined toward the upper surface from the bottom surface of the light guide plate and inclined surfaces which abut on the reflection surfaces on the lower surface of the light guide plate, the light radiation direction from the light guide plate is focused in the vertical direction with respect to the upper surface of the light guide plate.
