OPAQUE CONDUCTIVE OXIDE THIN FILM AND LIQUIDE CRYSTAL DISPLAY DEVICE USING SAME

摘要

An opaque conductive oxide thin film doped with a transition metal and a liquid crystal display device using the same are provided to improve a contrast ratio by including a pixel electrode and a common electrode formed by an opaque conductive oxide thin film. A gate line and a data line are formed on a substrate by turns, and define a pixel. A TFT(Thin Film Transistor) is formed on pixels, and is connected to the gate line and the data line. A pixel electrode(105) is formed by doping an opaque transition metal in a transparent conductive oxide, and is connected to the TFT. A common electrode(106) is formed on pixels, forms a horizontal electric field together with the pixel electrode, and is formed by doping an opaque transition metal in a transparent conductive oxide. The transparent conductive oxide includes one among ITO(Indium Tin Oxide) and ZnO(Zinc Oxide).
