  • Publication number: 20150129885
    Abstract: A method for forming a thin film according to an exemplary embodiment of the present invention includes forming the thin film at a power density in the range of approximately 1.5 to approximately 3 W/cm2 and at a pressure of an inert gas that is in the range of approximately 0.2 to approximately 0.3 Pa. This process results in an amorphous metal thin film barrier layer that prevents undesired diffusion from adjacent layers, even when this barrier layer is thinner than many conventional barrier layers.

The gate line includes a gate covering line formed in a first direction on the base substrate and a gate main line protruded from the gate covering line. The gate insulation layer is formed on the base substrate to cover the gate line. The data line is formed on the gate insulation layer in a second direction crossing the first direction. The TFT is electrically connected to the gate line and the data line. The pixel electrode is electrically connected to the TFT. Therefore, a gate line is thicker than a gate covering line and a gate main line having a low resistance is further formed, so that a gate signal may be quickly transferred along the gate line without a signal delay.

  • Patent number: 8218110
    Abstract: After increasing the thickness of a gate line and forming a barrier rib that is made of an organic material, a gate insulating layer is formed and then a color filter is formed with an Inkjet method using the barrier rib. By increasing a thickness of the gate line, even if the size of a substrate increases, problems due to signal delay are reduced, and by forming a barrier rib with an organic material, the height of the barrier rib increases, and a taper angle increases and thus a color filter is stably formed.
