GATE INSULATOR FILM FOR ORGANIC TFT AND ORGANIC TFT ELEMENT HAVING THE INSULATOR FILM

摘要

PROBLEM TO BE SOLVED: To provide a gate insulator film for an organic TFT, which comprises a curable composition giving a thin film being excellent surface water repellency and insulation properties; and an organic thin film transistor element using the same.;SOLUTION: The present invention is a gate insulator film for an organic TFT, which comprises a curable composition with an epoxy group-containing compound as a main component and is characterized by having a water contact angle of 95 degrees or more on a thin film surface after curing. The gate insulator film can be applied as an insulator film for an organic TFT due to its excellent insulation properties and high surface water repellency, and can give an organic TFT element expressing excellent transistor characteristics.;COPYRIGHT: (C)2013,JPO&INPIT
