  • Patent number: 6943853
    Abstract: A liquid crystal display (LCD) including a first substrate and a second substrate. A plurality of gate lines and data lines are formed on the first substrate perpendicular to each other to define a plurality of pixel regions. A thin film transistor is formed for every one pixel. A common electrode is formed on the second substrate. A gate pad, a data pad, and a common electrode pad electrically are connected to each of the gate lines, data lines, and common electrodes respectively. A data on/off pad is formed between adjacent data pads in substantially the same pattern as the data pad for testing a data signal applied to the pixel region. A gate on/off pad is formed between adjacent gate pads in substantially the same pattern as the gate pad for testing a gate signal applied to the pixel region. A common electrode on/off pad is provided for testing a common electrode signal applied to the pixel region.

  • Patent number: 6774973
    Abstract: This invention relates to a line-on-glass LOG type liquid crystal display panel that is capable of preventing the lack of hardening of a sealant and staining of the liquid crystal display panel. A liquid crystal display panel of a line-on glass type includes a picture display part having a plurality of liquid crystal cells formed between an upper substrate and a lower substrate, signal pads formed at the outer area of the picture display part for supplying driving signals inputted from an outer driver integrated circuit to the picture display part. Line-on-glass type signal lines are formed at the outer area by a line-on-glass method and supply voltage signals needed for driving the driver integrated circuit. A sealant formed on the outer area for joining the upper and lower substrate. A least one or more holes formed on line-glass-type signal lines at the area where the line-on-glass type signal lines overlap with the sealant allowing UV rays irradiated for hardening the sealant to pass through.
