  • Patent number: 9759946
    Abstract: A liquid crystal display device of a horizontal electric field type includes: a first electrode and a second electrode formed on a liquid-crystal-side surface of the first transparent substrate, and two polarization plates respectively adhered such that respective transmission axes thereof are orthogonal to each other, wherein the liquid crystal material is rotated by an electric field generated between the first electrode and the second electrode. With respect to the transmission axis located in an extending direction between the first electrode and the second electrode, an initial orientation direction of the liquid crystal material is within a range between a direction rotated by 0.5-degree in an opposite response direction of the liquid crystal material and a direction orthogonal to an electric field direction generated between the first electrode and the second electrode.

  • Patent number: 9729848
    Abstract: The display device includes a display panel on which sub-pixel pairs are arranged in a lateral direction, and a parallax barrier shutter panel on which sub-openings that can be changed between a light transmittance state and a light-shielding state are arranged in a lateral direction. Arbitrary allocated number of adjacent sub-openings among the plural sub-openings belonging to a reference parallax barrier pitch are put into a light transmittance state, and the remaining sub-openings are put into a light-shielding state, so that a general opening is formed on the parallax barrier shutter panel. A sub-opening pitch of the sub-opening on the boundary part between the adjacent common driving areas is different from the sub-opening pitch of the other sub-openings.

  • Patent number: 9412312
    Abstract: A one-pixel structure of a display panel included in an auto-stereoscopic image display device adopts an in-plane switching mode. Transparent counter electrodes that are not provided in a liquid crystal panel of a normal in-plane switching mode are formed correspondingly to pixel peripheral regions on a second transparent substrate side and, in 3-dimensional image display, a vertical electric field is forcibly generated between the transparent counter electrodes and the comb-shaped electrodes, which causes the liquid crystal molecules to rise to show black display in the pixel peripheral regions. In 2-dimensional image display, meanwhile, the transparent counter electrodes are set to be floating, and the display panel is caused to have a structure substantially equivalent to a structure in which the transparent counter electrodes are not provided, to thereby make the display in pixel peripheral regions identical to the display (brightness) in a pixel main region.
