Abstract

A low-resistance wiring structure and a liquid crystal display are disclosed. The liquid crystal display includes a first substrate; a thin film transistor (TFT) formed on the first substrate and formed of a gate wiring, a data wiring and a semiconductor layer; and a second substrate attached to the first substrate in a facing manner, wherein at least one of the gate wiring and the data wiring is formed as a first wiring made of copper, a second wiring made of a barrier metal preventing spreading of copper, and a metal oxide film pattern formed between the first and second wirings. A MO/Cu wiring structure is implemented by using pure molybdenum, so that the low-resistance wiring structure with high reliability can be formed at a low cost.
