Abstract:
1. A method of manufacturing a thin film transistor substrate, comprising: forming on a surface of a substrate a first conductive pattern group including a gate line, a gate electrode, and a gate pad electrode; forming a gate insulating layer on the surface of the substrate on which the first conductive pattern group is formed; forming on the gate insulating layer an oxide semiconductor pattern overlapping the gate electrode; sequentially forming a first conductive layer and a second conductive layer on the surface of the substrate on which the oxide semiconductor pattern is formed, the first conductive layer formed of a transparent conductive material, and the second conductive layer formed of a metal material; and patterning the first and second conductive layers to form a second conductive pattern group including a data line, a source electrode, a drain electrode, and a data pad and to form a pixel electrode, the pixel electrode integrally formed with the first conductive layer of the drain electrode.
