A word of caution in manufacturing of organic-TFT with flexible substrate
■Case of using flexible substrate with film shape
■Organic-TFT and device are manufactured on original substrate, and then transferred to plastic film
■Resin is coated on support substrate and cured, and then, organic-TFT and device are manufactured on resin film, finally, support substrate is released (the resin film is used as substrate)
