Patent ID: 8013326

Claim:
An organic thin film transistor substrate, comprising: a gate line formed on a substrate; a gate electrode connected to the gate line; a data line comprising a first data line and a second data line disconnected from each other, formed on the substrate, and insulated from the gate line; a gate insulation layer formed on the gate electrode, the gate line, and the data line, the gate insulation layer having a source-connecting portion and a drain-seating groove, which are recessed from a surface of the gate insulating layer, and having a third contact hole to expose a portion of the data line; a source electrode formed in the source-connecting portion; a drain electrode formed in the drain-seating groove; an organic semiconductor layer contacting the gate insulation layer, the source electrode and the drain electrode, and wherein the gate insulation layer has a bridge groove recessed from the surface of the gate insulation layer, and a data bridge electrode formed in the bridge groove to connect the first data line and the second data line.
