Abstract
A thin film transistor array substrate including a gate line and a data line formed on a substrate, the gate and data lines crossing each other; a gate insulation film formed between the gate and data lines; a gate electrode formed at an intersection of the gate and data lines; an active layer formed on the gate insulation film to overlap the gate electrode; an etch stop layer formed on the active layer to define a channel region of the active layer; and a source electrode and a drain electrode formed on the active layer to partially overlap the active layer. The etch stop layer is between the source and drain electrodes, and the source and drain electrodes are spaced apart from the etch stop layer.
