  • 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.
