  • Patent number: 7593077
    Abstract: An LCD array substrate for a transflective-type LCD includes an E-field reflecting section formed under a transmitting window that reflects light when an electric field is applied. A gate line, a gate electrode and a transparent electrode are formed on a substrate. A channel layer between source and drain electrodes and an E-field reflecting layer are formed on the gate electrode and the transparent electrode, respectively. Portions of a protecting layer are removed to form a contact hole disposed over the drain electrode, and a light-transmitting hole over the E-field reflecting layer. A pixel electrode that is electrically connected to the drain electrode through the contact hole, makes contact with the E-field reflecting layer through the light-transmitting hole.

  • Publication number: 20090075308
    Abstract: The present invention relates to a method for in vitro phosphorylation of TRAP derived from Staphylococcus aureus. In the present invention, the TRAP is first identified as a kinase that self-phosphorylates and is phosphorylated specifically in the presence of an oxidative metal ion such as iron, copper and zinc. Based upon this finding, a novel method for in vitro phosphorylation of purified TRAP is provided and also, a method for screening various chemicals and natural materials by using the above method is provided in order to select inhibitors against the TRAP phosphorylation. The inhibitors are expected to be applied for novel antibiotics of Staphylococcus aureus, because this TRAP phosphorylation is essential to infect Staphylococcus aureus. Therefore, the present invention can be widely used to develop novel drugs against Staphylococcus aureus and their resistant strains, in near future.
