Active matrix substrate and method for manufacturing same

The invention relates to an active matrix substrate and method for manufacturing the same. An active matrix substrate of a liquid crystal panel of an FFS mode includes gate lines, data lines, pixel circuits each including a switching element and a pixel electrode, a protective insulating film formed in a layer over these elements, and a common electrode formed in a layer over the protective insulating film. The data line includes a lower layer conductor part formed using indium tin oxide together with the pixel electrode, and an upper layer conductor part formed using molybdenum niobium and analuminum alloy. The lower layer conductor part is formed in a disconnected shape at a position of the switching element, and the upper layer conductor part is formed in a continuous shape so as to overlap with the lower layer conductor part. With this, an active matrix substrate capable of preventing a disconnection failure of the data line and an alignment failure is provided. 本发明涉及一种有源矩阵基板及其制造方法。FFS模式的液晶面板的有源矩阵基板具备：多个栅
