ABSTRACT:
A liquid crystal display device and method for manufacturing thereof include a gate electrode and a gate bus line over a substrate. An insulating layer, including at least one of PbOx, Bi2O3, BaO, SrO, TiO2, Nb2O5, ZnO, Zr2O3, and MgO, is formed over the gate electrode, the gate bus line, and the substrate. A semiconductor layer is formed on the insulating layer over the gate electrode, and an ohmic contact layer having first and second portions is formed on the semiconductor layer. Source and drain electrodes are formed on the first and second portions of the ohmic contact layer, respectively, and a pixel electrode is formed contacting the drain electrode and over the insulating layer. The gate bus line, the insulating layer, and the pixel electrode form a capacitor.
