Abstract:
A method for producing a thin film transistor, comprising the steps of:forming a gate electrode, a gate insulating film, a semiconductor layer, a source electrode and a drain electrode on a transparent insulating substrate;applying a transparent insulating synthetic resin having an upper flat surface onto said thin film transistor, thereby forming an interlayer insulating film and eliminating a level difference of said thin film transistor;providing a contact hole, thereby exposing a part of the surface of said drain electrode; andforming a pixel electrode comprising a transparent conductive film on said interlayer insulating film so that said pixel electrode is electrically connected with said drain electrode through said contact hole on a contact surface;applying a surface treatment to an entire surface of said interlayer insulating film, thereby removing a photoresist residue from said contact hole.
