Abstract

A thin film transistor substrate for a liquid crystal display device includes a substrate, a metal layer on the substrate, and an aluminum complex oxide layer on the metal layer. The aluminum complex oxide layer comprises at least one selected from the group consisting of zirconium, tungsten, chromium and molybdenum. A passivation layer is formed on the aluminum complex oxide layer through a dipping process.
