  • Patent number: 9087972
    Abstract: A flat panel display device and method of manufacturing the display device. The display device comprises a first substrate and a connection pad located along a side of the first substrate. A second substrate overlaps with the first substrate, wherein the second substrate does not overlap with an exposed portion of the first substrate. A first contact pad electrically couples the second substrate and the first substrate. A first distance from the side of the first substrate to a boundary between the exposed portion of the first substrate and the second substrate is greater than a second distance from the side of the first substrate to the first contact pad. The display device may be, for example, a touch capable display device that uses the first contact pad to transfer touch sensing signals from the second substrate to the first substrate.
