    摘要： A backlighting device for use with display panels has a plurality of light diffusing elements formed in dots or stripes on one of the two major faces of a light conducting plate that is made of a light-transmissive material. The device also has a linear light source provided in proximity to the end portion of at least one side of the light conducting plate. In the device, at least one sheet that is made of a light-transmissive material and which has a multiple of prisms or raised structures having straight ridgelines defined by the apices and minima of the raised structures at small intervals on the same side of the sheet. The sheet is arranged in such a manner that the ridgelines are substantially parallel to one another and is located on an exit face of the light conducting plate in such a way that the straight ridgelines intersect that sides of the major face of the light conducting plate or intersect imaginary lines or stripes that would be drawn when the light diffusing elements are formed on the light conducting plate.

    摘要： A back lighting device which comprises a light conducting plate made of a light-transmissive material, a linear light source provided in proximity to the end portion of at least one side of the light conducting plate, a reflecting plate or film that covers the linear light source and which consists, in order from the light source side, of a specular reflecting plate or film, an air layer and a light diffusing/reflecting plate or film in superposition. One surface of the light conducting plate is provided with a light diffusing capability and covered with a specular or light diffusing/reflecting plate. Thereby, it is possible to provide a back lighting device that has a high efficiency of power to luminance conversion and which hence is capable of achieving high luminance.

    摘要： In a liquid-crystal display (10), unpolarized light from a light source (12) passes through a linear polarization separation layer (14) and strikes a liquid-crystal cell (16). The liquid-crystal cell (16), in response to an applied electrical field, changes the direction of a director, so as to change the direction of the electrical field oscillation vector of the incident linearly polarized light by substantially 0 to 90°, this light then striking a dichroic linear polarization layer (18) on the surface, whereby only a component coincident with the polarization transmission axis thereof is allowed to exit to the outside. The dichroic linear polarization layer (18) transmits 50% of this incident light, and absorbs the remaining 50%.

    摘要： Provided herein is a retardation optical element 10 that produces no bright and dark fringes on a displayed image even when placed between a liquid crystal cell 104 and a polarizer 102B and thus can effectively prevent lowering of display quality. The retardation optical element 10 includes a retardation layer 12 having a cholesteric-regular molecular structure with liquid crystalline molecules in planar orientation. The helical pitch in the molecular structure of the retardation layer 12 is so adjusted that the retardation layer 12 can, owing to its molecular structure, selectively reflect light whose wavelength falls in a range different from the wave range of light incident on the retardation layer 12 (the selective reflection wave range of the retardation layer is either shorter or longer than the wave range of the incident light). Further, the retardation layer 12 has two opposite main surfaces (larger surfaces) 12A and 12B that are perpendicular to each other in the direction of thickness, where the directions of the directors Da of the liquid crystalline molecules on the entire area of the one surface 12A are substantially the same, and those of the directors Db of the liquid crystalline molecules on the entire area of the other surface 12B are also substantially the same.
