  • Publication number: 20090033826
    Abstract: A display device which enables size reduction, particularly in the frame thereof, and allows a thinner liquid crystal panel and a larger screen is provided. Positioning of a liquid crystal panel is performed by contacting the outer periphery of a back side polarizing plate, which is affixed to a second transparent substrate configuring the main part of the liquid crystal panel, with the inside of a protruded fitting portion formed on the frame of a backlight assembly. Thereby, the display panel can be positioned securely without enlarging the outside dimension of the front chassis and the frame. This enables to realize a small-size display device, particularly, size reduction in the frame of the front chassis and reduction of the outside dimension.

  • Patent number: 6888611
    Abstract: In a liquid-crystal display element each individual liquid-crystal injection area is surrounded by a seal, and the overall liquid-crystal injection area is surrounded by an array substrate and an opposing substrate surrounded by an outer peripheral seal having an aperture and are adhered together, the aperture of the outer peripheral seal being sealed by a hole sealant, and the surface of at least one of the array substrate and the opposing substrate being polished with a polishing material, which is then removed, after which cutting along the aperture is done to separate the individual liquid-crystal injection areas, thereby facilitating the achievement of a thin liquid-crystal display element, while improving the quality and yield thereof.
