  • Publication number: 20160202587
    Abstract: A display panel includes an array substrate, an opposite substrate facing the array substrate, and a liquid crystal layer disposed between the array substrate and the opposite substrate. The array substrate includes a display area and a non-display area surrounding the display area, and the non-display area includes a first non-display area disposed adjacent to a side portion of the display area and a second non-display area other than the first non-display area. The first non-display area overlaps the opposite substrate. The array substrate and the opposite substrate have the same or substantially the same area and a wire member is disposed under the array substrate to be connected to an external circuit module. Accordingly, the display panel does not need an extra space for the wire member, and thus the non-display area is reduced.

  • Patent number: 9236237
    Abstract: Instead of sealing together the upper and lower panels of a display device with only a solid-filled sealing material, a vacuum region is provided in suction-force-applying communication with at least one of the panels and anchored to the other so as to pull the panels together due to pressure difference with and ambient atmosphere. The display device includes: a vacuum region defined by a pair of spaced apart, resilient and gas impermeable support barriers formed to integrally extend from at least one of the upper and lower panels of the display device and having the other end in vacuum region closing contact with the other display panel where the vacuum region is positioned in a peripheral area of the display device.
