  • Patent number: 9188789
    Abstract: A display device for displaying a first image in a first direction and a second image in a second direction, including a display panel having pixels arrayed in a matrix, a backlight configured to emit a light to a back surface of the display panel, and a parallax barrier configured so that a light from the first pixel passes through an opening of the parallax barrier and is emitted to the first direction, and a light from the second pixel passes through the opening of the parallax barrier and is emitted to the second direction. The formula (B?A)/A?1 is satisfied wherein A represents the luminance of the first image when the first image and the second image are black images, and B represents a luminance of the first image when the first image is a black image and the second image is a white image.

  • Patent number: 8873142
    Abstract: A display panel includes a panel section having a display area in which a plurality of display pixels are two-dimensionally disposed and a ring-like frame area provided at the periphery of the display area, and a barrier section that is disposed at a position opposed to the panel section and has a barrier pattern composed of a light blocking area and a light transmissive area. Both the light blocking area and the light transmissive area are disposed in a first area opposed to the display area and a ring-like second area opposed to the frame area.
