INSULATING LAYER, ELECTRONIC DEVICE, FIELD EFFECT TRANSISTOR, AND POLYVINYLTHIOPHENOL

摘要

For the purpose of providing an insulting layer which enables to improve device characteristics when used in an electronic device, a polymer insulator containing a repeating unit represented by the formula below is contained in the insulating layer. In the formula, R^a represents a direct bond or an arbitrary linking group; Ar represents an optionally substituted divalent aromatic group; and R^b represents a hydrogen atom, a fluorine atom or a monovalent organic group.
