  • Patent number: 8841669
    Abstract: A method of manufacturing a flat panel display device includes: forming a semiconductor layer of a thin film transistor (TFT) on a substrate; forming a gate electrode on the semiconductor layer with a gate insulating layer between the gate electrode and the semiconductor layer, and doping source and drain regions of the semiconductor layer with ion impurities; sequentially forming a first conductive layer, a first insulating layer, and a second conductive layer, and forming a capacitor at a distance away from the TFT by patterning the first conductive layer, the first insulating layer, and the second conductive layer; forming a second insulating layer, and forming contact holes passing through the second insulating layer, the contact holes exposing portions of the source and drain regions and the second conductive layer; and forming source and drain electrodes that respectively contact the source and drain regions and the second conductive layer through the contact holes.

  • Patent number: 8754996
    Abstract: Embodiments relate to a liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel includes a first substrate; a second substrate facing the first substrate; a liquid crystal layer between the first substrate and the second substrate; a gate line extended in a first direction on the first substrate; a data line on the first substrate and extended in a second direction, crossing the first direction; and a common voltage line on the same layer as the gate line. The common voltage line includes: a plurality of first lines and a plurality of second lines extended in the first direction and separately disposed with a cutting unit therebetween; a first connector for connecting the first lines; and a second connector for connecting the second lines.
