COMPOSITION CONTAINING POLYIMIDE DERIVATIVE FOR PREPARING ORGANIC GATE INSULATOR AND ORGANIC GATE INSULATOR AND ORGANIC THIN FILM TRANSISTOR USING THE SAME

摘要

PURPOSE: A composition for forming an organic insulator is provided to enable application to organic thin film transistors as driving switching devices in a next generation flexible display and photocuring by a low-temperature process and photopolymerization process. CONSTITUTION: A composition for forming an organic insulator comprises a polyimide derivative having a hydroxy group of chemical formula 1 and an epoxy compound of chemical formula 2 or an epoxy compound of chemical formula 3, and further at least one of photoinitiators or organic solvents. An organic thin film transistor successively includes glass or plastic substrate, gate electrode, organic insulating film, oragnic semiconductor layer, source electrode and drain electrode.
