Abstract:
1. An active matrix substrate, comprising: a substrate; a matrix array of thin film transistors (TFTs) disposed within a display area on said substrate; a double-layered film including an under-layer of aluminum-neodymium (Al—Nd) alloy and an over-layer of high melting point metal, said double-layered film forming first anisotropically dry-etched interconnection lines for connection to said TFTs; and a triple-layered film including an under-layer of said high melting point metal, a middle-layer of said Al—Nd alloy and an over-layer of said high melting point metal, said triple-layered film forming second anisotropically dry-etched interconnection lines for connection to said TFTs, wherein said Al—Nd alloy contains less than about 1.00 wt % neodymium (Nd).
