A fast‐response flexible ferroelectric liquid crystal (FLC) display panel driven by organic TFT (OTFT) was successfully developed. The fabricated OTFT with Ta 2 O 5 gate insulator showed a mobility of 0.3 cm 2 /Vs and a current on/off ratio of 10 7 with a low operating drain voltage of −5 V. We obtained fast responses of less than 1 msec and contrast ratio of 14:1 with gray‐scale display capability from a 16×16 pixel FLC panel.
