  • Patent number: 7646021
    Abstract: A TFT array substrate includes a substrate, a patterned first metallic layer, a patterned stack layer, a patterned dielectric layer, a patterned transparent conductive layer, and a patterned third metallic layer. Elements of each TFT in the TFT array substrate are arranged vertically, so that the TFT array substrate has relatively small fabrication area and is operable with a high conducting current. Further, the storage capacitance can be enhanced by enclosing or sandwiching the second metallic layer with the common lines and the transparent electrodes. In such a way, pixel flashing caused by those coupled signals can be reduced, thus promoting displaying quality thereof.

  • Patent number: 7576015
    Abstract: A method for manufacturing an alignment layer is provided, which includes the following steps. First, a substrate is provided. Next, an auxiliary layer is formed on the substrate. Then, an alignment solution is sprayed on the auxiliary layer through an inkjet printing process. The alignment solution includes an alignment material and a first solvent, and the auxiliary layer has the same polarity as the first solvent. Then, by performing a curing process, the alignment solution is cured to form an alignment layer. As mentioned above, the method for manufacturing an alignment layer may be applied to manufacture an alignment layer with preferred smoothness.

  • Publication number: 20070291218
    Abstract: A method for manufacturing a liquid crystal display (LCD) panel, which uses an inkjet process to locate the spacers adjacent the protrusions to uniform the thickness of the liquid crystal layer. The spacers are located in the regions which are under/above the black matrix or the metal lines. Accordingly, the light leakage caused by the spacers is not present in the pixel region. Thus, an inventive LCD device can avoid the problem of light leakage generated by the pixel region of an LCD device with the conventional scattered spacers, and provide a high-contrast display quality. Further, the cost for manufacturing LCD devices can be effectively reduced, and the requirement of large-sized panel development can be met.

    Abstract: A method of forming an alignment layer is described. A substrate comprising a display area and a non-display area is provided. A hydrophilic layer is formed on the substrate of the display area. A solution of an alignment material is dropped on the hydrophilic layer. The solution of the alignment material is solidified to form an alignment layer. Before dropping the solution of the alignment material on the hydrophilic layer, a hydrophobic layer may be formed on the substrate of the non-display area.
