  • Patent number: 9454050
    Abstract: LCD device includes two substrates, a first and second color filters, two liquid crystal layers. The first color filters are formed on portions of the second substrate corresponding to border area The second color filters are formed on portions of the second substrate corresponding to the display area except the border area. A first liquid crystal layer between the first and the second substrate is comprised in border area, and a zero electric field is formed on the first liquid crystal layer so as to completely transmit light incident into the first liquid crystal layer therethrough. A borderline having various colors can be displayed by forming various patterns of color filters having various colors on portions of the second substrate corresponding to the border area under normally white mode, thereby producing picture frame effect while images are displayed on the screen.

  • Patent number: 9095017
    Abstract: An organic light-emitting display device is provided. The organic light-emitting display device includes a substrate; a display unit on the substrate; and a sealing substrate on the display unit. The sealing substrate includes a first surface facing the display unit and a second surface opposite to the first surface. A first barrier layer is on the first surface or the second surface of the sealing substrate. Thus, the organic light-emitting display device may easily reduce or prevent penetration of external air and moisture.
