Provided are an organic thin film transistor providing smoother movement of holes between a source electrode or a drain electrode and a p-type organic semiconductor layer, and a flat panel display device including the organic thin film transistor. A feedback signal regarding the parameter of the process is received via a sensor of the process and a first feedback loop. The first knitted conductive textile plane has conductive yarn knitted to form a repeating pattern of stitches each comprising a stitch looping portion SLP having a looping portion footprint LPF.
