A 4.8‐in. VGA (167 dpi) organic thin‐film transistor (OTFT) ‐ driven flexible electrophoretic display was demonstrated by developing inkjet printing of a small‐molecule organic semiconductor (OSC) peri‐xanthenoxanthene derivative. A passivation layer of OSC was also printed by the screen‐printing method. Pixel OTFTs exhibited high mobility of 0.4 cm 2 /Vs and high thermal stability after full integration of the field shielded pixel structure.
