Abstract:
1. An electronic arrangement comprising a thin film transistor with a source electrode and a drain electrode, which are separated from each other by a channel, and a gate electrode, which is separated from the channel by means of dielectric material, said arrangement having: a substrate, on one side of which there is: an active layer, which comprises an organic semiconductor material, and within which the channel is located; a first electrode layer, within which the source electrode and the drain electrode are defined; an intermediate layer of dielectric material; and a second electrode layer, within which the gate electrode is defined, said gate electrode, when perpendicularly projected onto the first electrode layer, substantially overlapping the channel; characterized in that a side of the active layer facing away from the substrate is in contact with a protective layer, the protective layer being a substantially electrically non-conductive material, and which active and protective layers are structured in a same two-dimensional pattern, the protective layer and same two-dimensional pattern structure providing a thin film transistor arrangement with a lowered leakage current and lower threshold voltage; the thin film transistor is a component of a first display element; and further display elements with thin film transistors are present, which first and further display elements are arranged in a matrix.
