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

摘要

Provided is an insulating layer that can improve device characteristics of an electronic device including the insulating layer. The insulating layer contains a polymer insulating substance having repeating units represented by the following formula: wherein Ra represents a direct bond or any linking group, Ar represents a divalent aromatic group optionally having a substituent, and Rb represents a hydrogen atom, a fluorine atom, or a univalent organic group.
