Patent ID: 7709834

Claim:
An organic thin film transistor substrate comprising: a gate line formed on a substrate; a data line which crosses with the gate line to define a pixel area; an organic gate insulating layer interposed at least between a gate electrode defining portion of the gate line and a source electrode defining portion of the data line, where said gate electrode defining and source electrode defining portions are parts of a thin film transistor which further includes a drain electrode and an organic semiconductive layer; a pixel electrode connected with the drain electrode of the thin film transistor and extending over a substantial portion of said pixel area; an organic protective layer covering the organic semiconductive layer and peripheral other areas of the thin film transistor; a first border-defining insulating layer that has a step-like contour for defining first and second containment holes into which materials of the organic gate insulating layer and of the organic protective layer may be filled, and a second border-defining insulating layer formed on the source electrode portion and the drain electrode of the thin film transistor so as to further define the second containment hole into which the material of the organic semiconductive layer may be filled.
