    摘要： A reflective liquid crystal display panel is a display panel for three-dimensional display in which pixel pairs as display elements composed of one left-eye pixel L and one right-eye pixel R each are provided in a matrix. The lenticular lens is an optical member for image separation that is provided to separate the light from the left and right pixels, and numerous lenticular lenses form a lens array that is arranged in one dimension. An anisotropic scattering sheet as an anisotropic scattering element is provided between the lenticular lens and the reflective liquid crystal display panel. According to this configuration, a reduction in the quality of the reflective display can be minimized, and improved image quality can be achieved without changing the concavo-convex structure of the reflecting panel and the lens shape of the lenticular lens in display device that is capable of displaying different images to a plurality of viewpoints.

    摘要： A plurality of pixels is arranged periodically in the x-axis direction and the y-axis direction in the display panel of a display device, and because light is blocked by the portion other than the open part in each pixel, the display panel has a two-dimensional lattice structure. The pixels are rectangular, and the length Px of the long edges in the x direction is larger than the length Py of the short edges in the y direction. A louver, in which transparent regions and non-transparent regions are arranged periodically in a one-dimensional direction, is provided on the display panel, and the angle formed by the x axis and the one-dimensional period direction of the louver is 45 degrees or less, and preferably 10 degrees or less. This configuration makes it possible to obtain an optical element having high directivity, reduced moiré, and high transmittance. It is also possible to obtain a display device having excellent display quality into which the optical element is incorporated.

    摘要： In a display device equipped with a light source device, a second light-guide member is provided to the back surface of a first light-guide member that has an emitted light control sheet provided to the front surface thereof. The emitted light control sheet is composed of a flat plate portion and protrusions. A first light source mounted to a side surface of the first light-guide member, and a second light source mounted to a side surface of a second light-guide member are switched and turned on. The emitted light control sheet has light-condensing effects when the first light source is on, and has diffusing effects when the second light source is turned on. The angle range of illuminating light can thereby be switched.

    摘要： In a liquid crystal display device, a liquid crystal layer is provided between a principal substrate and an opposing substrate that are disposed so as to face each other, and a shared electrode and a pixel electrode, which is a parallel electrode pair formed in the shape of a comb, are formed on the surface of the principal substrate that faces the opposing substrate. Orientation films are also formed on the opposing surfaces of the principal substrate and the opposing substrate. The electrodes of the parallel electrode pair are formed so that the width thereof is smaller than the thickness of the liquid crystal layer. The orientation of the liquid crystal molecules between the electrodes is thereby changed by an electric field generated by the parallel electrode pair, and the orientation of liquid crystal molecules disposed above the electrodes is changed in the same direction as in the liquid crystal molecules between the electrodes in accordance with the change in orientation of the liquid crystal molecules between the electrodes. A high degree of transmittance can thereby be achieved by a simple electrode structure in an in-plane switching liquid crystal display device.

    摘要： In a display device, white LEDs and bluish white LEDs are arranged in alternating fashion on the light-incident surface side of a light-guide plate. On the light-exit side of the light-guide plate is disposed a transparent/scattering switching element switchable between a state of scattering incident light, and a state of transmitting light unchanged without scattering. During a narrow-angle display, only the white LEDs are lit, and the transparent/scattering switching element is placed in the transparent state, while during a wide-angle display, both the white LEDs and the bluish white LEDs are lit, and the transparent/scattering switching element is placed in the scattering state.
