Abstract

A thin film transistor array panel includes an insulating substrate, a gate line formed on the insulating substrate, a gate insulating layer formed on the gate line, a drain electrode and a data line having a source electrode formed on the gate insulating layer wherein the drain electrode faces the source electrode with a gap therebetween, and a pixel electrode connected to the drain electrode. At least one of the gate line, the data line, and the drain electrode includes a first conductive layer made of a conductive oxide and a second conductive layer of Ag that is deposited adjacent to the first conductive layer.
