Abstract: A liquid crystal display device of IPS mode includes an array of pixels arranged in a matrix pattern by crossing a plurality of video signal lines and a plurality of scanning signal lines each other. Each of the pixels is provided with at least a switching element. A transparent insulating film is provided on both signal lines, and a plurality of pixel electrodes, common electrodes and common lines are provided on the transparent insulating film. The common lines are formed in a grid-shaped pattern such that a first group of the common lines is made of a first conductor having lower reflectivity against optical light than that of metal while a second group of the common lines is made of a second conductor including a metal layer such that said first group and said second group are crossing each other along said video signal lines and said scanning signal lines.

Abstract: A liquid crystal display device comprises a plurality of pixels arrayed in a first direction and a second direction, each of the pixels having a reflective area in at least a portion thereof. The reflective area comprises a surface-irregularity film that is a film having a plurality of surface irregularities, a light reflecting film disposed as an upper layer over the surface-irregularity film, and an electrode group disposed as an upper layer over the light reflecting film. The electrode group in each of the pixels that are arrayed in at least the first direction comprises at least two types of electrode patterns having different layouts.

Abstract: 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.
