  • Patent number: 11428969
    Abstract: An optical display includes an optical display element including a second substrate, a first substrate facing the second substrate, a dummy region and a metal interconnection layer thereon. A first polarizing plate on an upper surface of the optical display element has a light shielding layer therein including printed patterns separated from each other. A first printed layer includes a first point at an interface between the display and non-display regions and a second point at a vertex closest to the first point. A second printed layer includes a third point at the interface and a fourth point at a vertex closes to the third point. The light shielding layer satisfies H?P/2, where H is a minimum value among a distance from the interface to the second point and a distance from the interface to the fourth point, and P is a width of the dummy region.

  • Patent number: 10991646
    Abstract: A flexible circuit board for a display, having a chip-on-film structure, is disclosed. A connection pattern which is selected as a first connection pattern among connection patterns connected to panel contact pads does not reach a cutting line and is confined within a product region. As a consequence, the connection pattern selected as the first connection pattern may be prevented from being exposed on a cutting section along the cutting line, and thus, may be prevented from being changed in its electrical property due to penetration of moisture.
