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： A planar light source, Fresnel lens sheet, and louver are disposed in the stated order in a light source apparatus. The Fresnel lens sheet deflects and focuses in one dimension light that has entered from the planar light source. The louver is disposed in the optical path of the light emitted from the Fresnel lens sheet, and the directivity of the light can be increased by restricting the traveling direction of the light to the focal direction of the Fresnel lens sheet. The light utilization ratio can thereby be increased, the directivity of planarly emitted light can be increased, and the brightness can be made uniform at the point of observation.

摘要： A display device comprising a light source and having an optical waveguide, a louver, an anisotropic scattering sheet, and a transmissive liquid crystal panel disposed along the path of light emitted from the light source. The light-restricting direction of the louver is tilted at an angle α from the Y-axis direction. The value of the angle α is set so that the arrangement direction of moiré created between the louver and the liquid crystal panel approaches the X-axis direction. A plurality of belt-shaped convex portions extending in the Y-axis direction are formed on the surface of the anisotropic scattering sheet, and are configured so that the scattering direction of the light has anisotropy. Specifically, scattering in the X-axis direction is increased, and scattering in the Y-axis direction is reduced. Moiré can thereby be reduced in a display device having increased directivity of the display.

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.
