    摘要: A method of manufacturing a display substrate includes forming a first metallic pattern including gate and storage conductors and a gate electrode of a switching device on a base substrate, forming a gate insulation layer, forming a second metallic pattern and a channel portion including a source line, source and drain electrodes of the switching device, forming a passivation layer and a photoresist film on the second metallic pattern, patterning the photoresist film to form a first pattern portion corresponding to the gate and source conductors and the switching device, and a second pattern portion formed on the storage line, etching the passivation layer and the gate insulation layer, and forming a pixel electrode using the first pattern portion. Therefore, excessive etching of the stepped portion may be prevented, so that a short-circuit defect between a metallic pattern and a pixel electrode may be prevented

    摘要: 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.

    摘要: A metal wiring layer and a method of fabricating the metal wiring layer are provided. The method includes forming a dielectric layer on a substrate, forming a plurality of dielectric layer patterns and holes therein on the substrate by etching part of the dielectric layer, with a cross sectional area of the holes in the dielectric layer patterns decreasing with increasing distance away from the substrate and the holes exposing the substrate, forming a trench by etching a portion of the substrate exposed through the holes in the dielectric layer patterns, and forming a metal layer which fills the trench and the holes in the dielectric layer patterns. Thus, it is possible to prevent the occurrence of an edge build-up phenomenon by forming a metal layer in a plurality of holes in the dielectric layer patterns having a cross sectional area decreasing with increasing distance away from the substrate. Therefore, it is possible to prevent the transmittance of a liquid crystal layer from decreasing due to a failure to properly fill liquid crystal molecules in the liquid crystal layer, and thus to increase the quality of display.
