  • Publication number: 20090179203
    Abstract: A display substrate includes an insulating substrate, a thin-film transistor (TFT), a pixel electrode, a signal line and a pad part. The insulating substrate has a display region and a peripheral region surrounding the display region. The TFT is in the display region of the insulating substrate. The pixel electrode is in the display region of the insulating substrate and electrically connected to the TFT. The signal line is on the insulating substrate and extends from the peripheral region toward the display region. The pad part is in the peripheral region and electrically connects to the signal line. The pad part is formed in a trench of the insulating substrate and includes a region that extends into the insulating substrate. Therefore, the signal line may be securely attached to the insulating substrate.

  • Publication number: 20080268581
    Abstract: A method of manufacturing a TFT substrate includes: sequentially forming a transparent conductive layer and an opaque conductive layer on a substrate, patterning the transparent conductive layer and the opaque conductive layer by using a first mask to form a gate pattern including a pixel electrode, and forming a gate insulating layer and a semiconductor layer above the substrate. A contact hole is formed which exposes a portion of the pixel electrode and a semiconductor pattern using a second mask. A conductive layer is formed above the substrate and patterned to form a source/drain pattern including a drain electrode which overlaps a portion of the pixel electrode. Portions of the gate insulating layer and the opaque conductive layer above the pixel electrode are removed except a portion overlapping the drain electrode, by using a third mask.
