  • Publication number: 20100181572
    Abstract: A data line and an amorphous silicon pattern are formed on a substrate. The first electrode pattern is extended from the data line and overlaps an edge of the amorphous silicon pattern. The second electrode pattern is made of the same metal as the first electrode pattern and overlaps the edge of the amorphous silicon pattern at an opposite side of the first electrode pattern. Edges of the first and the second electrode patterns are sharply formed so that a tunneling effect easily occurs through the amorphous silicon pattern. An indium-tin-oxide pattern for a capacitor is formed at the end of the second electrode pattern. The capacitor is formed between the ITO pattern and a common electrode.

  • Patent number: RE41426
    Abstract: An ITO (indium tin oxide) layer and a negative photoresist are deposited sequentially on the substrate 100 having a gate wire, a storage wire, a data wire and a storage electrode. The negative photoresist is developed through front exposure and the ITO layer is etched to form a pixel electrode. Because the portions of negative photoresist exposed to light remain after development, pixel defects due to particles placed between pixel regions are reduced. Both the rear exposure and the front exposure may be used. In the rear exposure, it is difficult to remain the portions of the ITO layer at the positions corresponding to the contact portion of the drain electrode and the pixel electrode, the storage line, the gate pads and the data pads. Accordingly, the front exposure is then executed by using the first mask having openings thereon. The negative photoresist is developed, and the ITO layer is patterned.
