We have demonstrated high‐performance and highly rollable flexible oxide TFTs on fully transparent/colorless polyimide substrates by adopting lithographic and etching processes and composite electrodes. The TFTs exhibited a field‐effect mobility of up to 15.9 cm 2 /Vs, a sub‐threshold swing of 0.43 V/decade, and an on/off ratio of > 10 8 . The devices could be bent down to a radius of 3 mm and yet remained normally functional.
