  • Publication number: 20090059109
    Abstract: An array substrate includes a transistor, a pixel electrode and an upper insulation layer. The transistor is formed on an upper insulation layer formed on a base substrate. The pixel electrode is electrically connected to the transistor. The upper insulation layer covers the transistor to directly make contact with the base substrate of an area having the pixel electrode formed thereon.

  • Publication number: 20090026463
    Abstract: An array substrate includes a thin-film transistor (TFT), a first insulation layer and a second insulation layer. The TFT is formed on the substrate. The TFT includes an active pattern, a gate metal pattern and a data metal pattern. The first insulation layer insulates the active pattern from the gate metal pattern. The second insulation layer is formed spaced apart by a predetermined width from at least one edge of the substrate. The second insulation layer insulates the gate metal pattern from the data metal pattern. Therefore, the second insulation layer is formed so that stress that is inflicted on a substrate may be decreased, thereby preventing deformation during a manufacturing process of the substrate.

  • Publication number: 20080113473
    Abstract: According to a method of manufacturing a thin-film transistor (TFT) substrate, a gate insulation layer, a semiconductor layer, an ohmic contact layer, and a data metal layer are sequentially formed on a substrate. A photoresist pattern is formed in a source electrode area and a drain electrode area. A data metal layer is etched using the photoresist pattern as an etch-stop layer to form a data wire including a source electrode and a drain electrode. A photoresist pattern is reflowed to cover a channel region between a source electrode and the drain electrode. An ohmic contact layer and the semiconductor layer are etched using the reflowed photoresist pattern as an etch-stop layer to form an active pattern including an ohmic contact pattern and a semiconductor pattern. The reflowed photoresist pattern is etched back to expose a portion of the ohmic contact pattern in the channel region. The ohmic contact pattern is etched using the etched-back photoresist pattern as an etch-stop layer.

  • Publication number: 20080087904
    Abstract: A thin film transistor array panel includes interconnection members interposed between the underlying gate pads made of an Al-containing metal and the overlying contact assistants made of a transparent conductor such as ITO thereon to prevent corrosion of Al due to ITO, or gate-layer signal transmission lines. Gate-layer signal transmission lines are directly connected to the data-layer signal transmission line to prevent corrosion of Al due to ITO in the thin film transistor array panel according to an embodiment of the present invention. The color filters are formed on the thin film transistor array panel to prevent misalignment between the two display panels so as to increase the aperture ratio.
