초록

In this work, the electrical characteristics of organic thin film transistors with the surface-treated organic gate insulator have been studied. For the surface treatment, the photoalignment technique was used. The field effect mobilities of the devices with PVP gate insulator was improved about ten times as high as those of TFTs without the insulator surface treatment.
