  • Patent number: 7637799
    Abstract: A substrate production apparatus for producing a substrate for a display device is disclosed. The substrate production apparatus includes a first production apparatus including a first scriber to scribe a first mother substrate into at least one first model substrate and at least one second model substrate, a first grinder to grind the first model substrate, and a first cleaning unit to clean the ground first model substrate. The substrate production apparatus also includes a second production apparatus including a second scriber to scribe a second mother substrate into at least one first model substrate and at least one second model substrate, a second grinder to grind the second model substrate, and a second cleaning unit to clean the ground second model substrate. Additionally, the substrate production apparatus includes a common buffer unit to store the second model substrate from the first production apparatus and to store the first model substrate from the second production apparatus.

  • Patent number: 7436478
    Abstract: An array substrate for a liquid crystal display device includes a substrate, a gate line and a gate link line on the substrate. The gate link line is extended from the gate line. A data line and a data link line cross over the gate line and the gate link line. The crossing of the data line and the gate line defines a pixel region. The data link line is extended from the data line. A thin film transistor is connected to the gate line and the data line. A dummy pattern is disposed between adjacent data link lines, and a pixel electrode is disposed at the pixel region.
