The device of the invention comprises a thin film transistor of an organic semiconductor material. This semiconductor material is patterned by applying first a protective layer and thereafter a photoresist. As a result hereof, the transistor of the invention (A) shows a very low leakage current and a low threshold voltage in comparison with prior art transistors (B,C).

Electronic arrangement including a thin film transistor having active and protective layers structured in a same two-dimensional pattern

Display device in which switching elements (5) are realized in an organic semiconductor layer. Mutual insulation of the elements and pixels is obtained either electrically by applying depletion via voltages to a guard line (4) or physically by making parts of the organic semiconductor layer insulating.
