In this work, we fabricated inkjet printed OTFT with CNT source‐drain electrode for plastic displays. 6,13‐bis(pentylphenylethynyl)pentacene was used for printable organic semiconductor. The OTFT with CNT electrode exhibited the field‐effect mobility of 0.15 cm 2 /Vs, threshold voltage of −3.4 V with on‐off current ratio of ∼10 7 . The performance is suitable for driving e‐paper display on plastic. Especially normalized contact resistance was 10 times lower than that of bottom‐contact pentacene TFT using Au S/D electrode.
