  • Patent number: 9709863
    Abstract: In a liquid crystal display device, a first substrate adjacent to a liquid crystal display panel is subjected to rubbing in a first direction that is the same as a polarization axis direction of light emitted from the liquid crystal display panel, and a second substrate that interposes a liquid crystal layer with the first substrate is subjected to rubbing in a second direction at a right angle with the first direction. The second direction is made the same as the polarization axis direction of polarized sunglasses to allow visual recognition of the image using the polarized sunglasses. Electrode patterns formed by alternately providing narrow and wide electrodes are arranged on the upper and lower substrates in a direction at a right angle with each other so that the rubbing directions on the upper and lower substrates form a right angle to ensure stable 3D display.
