Thin film transistor array substrate and manufacturing method thereof

Abstract

A substrate including a gate line and a gate electrode disposed on a substrate, an oxide semiconductor layer pattern overlapping the gate electrode, a gate insulating layer disposed between the gate electrode and the oxide semiconductor layer pattern, a data line intersecting the gate line, a source electrode electrically connected to the oxide semiconductor layer pattern, a drain electrode electrically connected to the oxide semiconductor layer, the drain electrode spaced apart from the source electrode, and an insulating pattern including a first portion, which is disposed between the gate line and the data line and at least partially overlaps with both of the gate line and the data line.
